+> 一个简单&强大的Web思维导图
 
-Demo：[https://wanglin2.github.io/mind-map/](https://wanglin2.github.io/mind-map/)
+本项目包含两部分：
 
-文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+1.一个js思维导图库，不依赖任何框架，你可以使用它来快速完成Web思维导图产品的开发。
+
+开发文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+
+2.一个Web思维导图，基于思维导图库、Vue2.x、ElementUI开发，可以操作电脑本地文件，所以你可以直接把它当做一个在线版思维导图应用使用，如果觉得github的响应速度慢，你也可以部署到你的服务器上。

 # Changelog
 
+## 0.5.7
+
+Breaking change：In rich text mode, exporting png has been changed to using html2canvas to convert the entire svg, greatly improving the export speed. However, html2canvas has a bug where the text color inline with the dom node in the foreignObject element cannot be recognized. Therefore, the text color of the exported node is fixed. However, compared to the previously unavailable state of the export, it can at least be exported quickly and smoothly.
+
+optimization: Optimize the rich text node editing experience.
+
+New: In rich text mode, importing data, initializing data, and switching theme scene node styles support following theme changes.
+
+## 0.5.6
+
+Fix: 1.Fix the issue of node position disorder during fast and multiple renderings in a short period of time. 2.Fix the issue of dragging the canvas while the node is being edited, causing the edit box and node to separate.
+
+New: 1.Add a maximum history limit.
+
+## 0.5.5-fix.1
+
+Fix: 1.Fix the issue where the edit box is also outside the canvas when editing nodes outside the canvas. 2.After modifying the structure, reset the transformation to prevent the problem of sudden position changes during the first drag after switching the structure during scaling.
+
+optimization: 1.When multiple nodes are selected, as long as there is a cross between the node and the selection area, it is considered selected.
+
+## 0.5.5-fix.2
+
+Fix: 1.Fix mini map error.
+
+## 0.5.5
+
+New: 1.Supports configuring the padding when exporting to PNG, SVG, or PDF. 2.Support the configuration of z-index for node text editing boxes and node comment floating layer elements. 3.Support clicking on areas outside the canvas to end node editing status.
+
+## 0.5.4
+
+New: 1.Add new themes. 2.Added timeline and fishbone structure.
+
+Fix: 1.Fix the conflict issue between node right-click and canvas right-click. 2.Fix the bug that the line segment is not hidden when dragging nodes such as organizational chart and directory organization chart.
+
+optimization: 1.Optimize the layout of organizational chart. 2.Optimize the layout of the directory organization chart.
+
+## 0.5.4-fix.1
+
+optimization: 1.Optimize fishbone layout.
+
+## 0.5.3
+
+Fix: 1.Fixed the issue of setting the text style when multiple nodes were selected in rich text mode, which would change the text of all selected nodes to the text of the last selected node.
+
+New: 1.Support setting the position of the initial central node.
+
+### 0.5.3-fix.1
+
+Fix: 1.Fix the issue where setting the position of the initial central node does not take effect.
+
+### 0.5.3-fix.2
+
+Fix: 1.Fix the issue of not displaying images in nodes when exporting as images.
+
 ## 0.5.2
 
 Fix: 1.Remove `uid` from exported `JSON` data; 2.Clear the node cache pool when re rendering.

+Zhixi is a free mind mapping product that supports multi end synchronization. The UI design is beautiful and the features are complete, but it is not open source, so it can only be used as a user and cannot be used in your project.
+
+There are many other online mind mapping products similar to Zhixi, such as [GitMind](https://gitmind.cn/)、[MindLine](http://www.mindline.cn/)、[MinMeister](https://www.mindmeister.com/zh)、[Mubu](https://mubu.com/) and so on, There are many searches on search engines, but these products either require fees or are developed by small companies, and their stability and sustainability cannot be guaranteed. Of course, the most crucial thing is that they are not open-source.

+`kityminder-core` is an open source brain mapping tool developed by Baidu. It has powerful functions and good performance, but it is no longer maintained. Therefore, the code is relatively old, and the interface beauty is relatively ordinary. In addition, bugs can only be fixed by yourself, and the functions can only be developed by yourself.

+## Installation
+
+> Things to note before version 0.2.0:
+
+```bash
+npm i simple-mind-map
+```
+
+`0.2.0` Notes for previous versions:
+
+> Note: This project is directly published in source code form and has not been
+> packaged. If compilation fails, a Vue CLI-created project can add the
+> following configuration to the vue.config.js file to allow babel-loader to

+> ```js
+> module.exports = {
+>   transpileDependencies: ["simple-mind-map"],
+> };
+> ```
+>
+> Other projects should modify the packaging configuration as needed.
+
+## Usage
+
+> The `web` directory of this repository provides a complete project based on `Vue2`. If you encounter any doubts about using it, you can refer to the implementation of this project.
+
+> To learn about its use in other frameworks, you can refer to the following unofficial implementations:
+>
+> 1.[https://github.com/huangyuanyin/hyy-vue3-mindMap](https://github.com/huangyuanyin/hyy-vue3-mindMap): A mind map based on Vue3.2+ElementPlus.
+
+Firstly, provide a container element with a width and height not equal to 0:
+
+```html
+<div id="mindMapContainer"></div>
+```
+
+Also, set the `CSS` style again:
+
+```css
+#mindMapContainer * {
+  margin: 0;
+  padding: 0;
+}
+```
+
+Then introduce the `simple-mind-map` library and create an instance:
+
+```js
+import MindMap from "simple-mind-map";
+
+const mindMap = new MindMap({
+  el: document.getElementById('mindMapContainer'),
+  data: {
+    "data": {
+        "text": "Root Node"
+    },
+    "children": []
+  }
+});
+```
+
+This will result in a mind map.
+
+If you want to implement a complete mind map, you usually need to develop some UI interfaces to achieve more functions through the interfaces provided by the `simple-mind-map` library.
+
+`simple-mind-map` supports rich configurations, events, commands, and some additional plugin extensions. Read the subsequent documentation to learn more.
+
+The non-packaged 'ES' module is introduced by default, and only contains core functions, not unregistered plugin content, which can effectively reduce the size. However, you need to configure the `babel` compilation `simple mind-map` in your project to prevent some newer `js` syntax some browsers not supporting it.
+
+If you need a file in the format of `umd` module, such as `CDN` in the browser, Then you can find the `simpleMindMap.umd.min.js` file and `simpleMindMap.css` file in the `/simple-mind-map/dist/` directory, copy it to your project, and then import it into the page:
+
+```html
+<link rel="stylesheet" href="simpleMindMap.css">
+<script scr="simpleMindMap.umd.min.js"></script>
+```
+
+A global variable `window.simpleMindMap` will be created.
+
+The disadvantage of this method is that it will contain all the content, including the plugins you have not registered, so the overall volume will be relatively large.
+
+（v0.5.4+）If you want to use the `ES` module directly on the browser side, you can find the `simpleMindMap.esm.js` and `simpleMindMap.esm.css` files in the `/simple-mind-map/dist/` directory.

+> 2.本教程的代码示例基于Vue3.x，但是您不必担心，因为simple-mind-map本身是框架无关的，所以即使某些Vue3的语法您看不懂也不会影响对于逻辑的理解。
+
+`simple-mind-map`的使用非常简单，提供一个宽高不为0的元素，然后创建一个实例即可：

+
+注意，我们还给容器元素设置了样式：
+
+```css
+#mindMapContainer * {
+    margin: 0;
+    padding: 0;
+}
+```
+
+这是为了避免节点内的文字因为默认样式而出现偏移。
+
+一个节点的基本数据结构如下所示：
+
+```js
+{
+    data: {
+        // 节点文本
+        text: '根节点',
+        // 图片
+        image: 'xxx.jpg',
+        imageTitle: '图片名称',
+        imageSize: {
+            width: 1152,
+            height: 1152
+        },
+        // 图标
+        icon: ['priority_1'],
+        // 标签
+        tag: ['标签1', '标签2'],
+        // 链接
+        hyperlink: 'http://lxqnsys.com/',
+        hyperlinkTitle: '理想青年实验室',
+        // 备注内容
+        note: '理想青年实验室\n一个有意思的角落',
+        // 概要
+        generalization: {
+            text: '概要的内容'
+        },
+        // 节点是否展开
+        expand: true,
+    },
+    children: []// 子节点
+}
+```
+
+`icon`目前只能使用内置的图标，完整图标可以在[icons.js](https://github.com/wanglin2/mind-map/blob/main/simple-mind-map/src/svg/icons.js)文件中查看。
+
+创建实例时还支持传递其他很多选项参数，完整选项列表可以在[实例化选项](https://wanglin2.github.io/mind-map/#/doc/zh/constructor/%E5%AE%9E%E4%BE%8B%E5%8C%96%E9%80%89%E9%A1%B9)查看。
+
+这样得到的思维导图可以通过鼠标和快捷键进行操作，比如单击某个节点可以激活它，双击某个节点可以编辑节点文本，按下`Tab`键会给当前激活的节点添加一个子节点，按下`Enter`键会给当前激活的节点添加一个兄弟节点等等，完整的快捷键列表可以参考[快捷键列表](https://github.com/wanglin2/mind-map/blob/main/web/src/config/zh.js#L246)。
+
+当然有些功能还是需要UI界面的，比如图标列表、编辑超链接等等，需要注意的是`simple-mind-map`库并不包含UI界面，所以需要你自己开发，然后通过`simple-mind-map`提供的相关API来操作，本教程的其他章节会向你介绍如何使用。

+<p>创建实例时还支持传递其他很多选项参数，完整选项列表可以在<a href="https://wanglin2.github.io/mind-map/#/doc/zh/constructor/%E5%AE%9E%E4%BE%8B%E5%8C%96%E9%80%89%E9%A1%B9">实例化选项</a>查看。</p>
+<p>这样得到的思维导图可以通过鼠标和快捷键进行操作，比如单击某个节点可以激活它，双击某个节点可以编辑节点文本，按下<code>Tab</code>键会给当前激活的节点添加一个子节点，按下<code>Enter</code>键会给当前激活的节点添加一个兄弟节点等等，完整的快捷键列表可以参考<a href="https://github.com/wanglin2/mind-map/blob/main/web/src/config/zh.js#L246">快捷键列表</a>。</p>
+<p>当然有些功能还是需要UI界面的，比如图标列表、编辑超链接等等，需要注意的是<code>simple-mind-map</code>库并不包含UI界面，所以需要你自己开发，然后通过<code>simple-mind-map</code>提供的相关API来操作，本教程的其他章节会向你介绍如何使用。</p>

+# 主题
+
+## 使用和切换主题
+
+`simple-mind-map`内置了很多主题，可以通过如下方式获取到所有的内置主题列表：
+
+```js
+import { themeList } from 'simple-mind-map/src/utils/constant'
+```
+
+可以在实例化`simple-mind-map`时指定使用的主题：
+
+```js
+new MindMap({
+    theme: 'minions'
+})
+```
+
+如果想动态切换主题也很简单：
+
+```js
+mindMap.setTheme('classic')
+```
+
+如果要获取当前使用的主题名称可以使用：
+
+```js
+const theme = mindMap.getTheme()
+```
+
+## 定义新主题
+
+除了可以使用内置的主题外，你也可以自定义新主题：
+
+```js
+import MindMap from 'simple-mind-map'
+
+// 注册新主题
+MindMap.defineTheme('主题名称', {
+    // 主题配置
+})
+
+// 1.实例化时使用新注册的主题
+const mindMap = new MindMap({
+    theme: '主题名称'
+})
+
+// 2.动态切换新主题
+mindMap.setTheme('主题名称')
+```
+
+最好在实例化之前进行注册，这样在实例化时可以直接使用新注册的主题。
+
+一个主题其实就是一个普通的对象，完整配置可以参考[默认主题](https://github.com/wanglin2/mind-map/blob/main/simple-mind-map/src/themes/default.js)，`defineTheme`方法会把你传入的配置和默认配置做合并。大部分主题其实需要自定义的部分不是很多，一个典型的自定义主题配置可以参考[blueSky](https://github.com/wanglin2/mind-map/blob/main/simple-mind-map/src/themes/blueSky.js)。
+
+```js
+MindMap.defineTheme('redSpirit', {
+    // 背景颜色
+    backgroundColor: 'rgb(255, 238, 228)',
+    // 连线的颜色
+    lineColor: 'rgb(230, 138, 131)',
+    lineWidth: 3,
+    // 概要连线的粗细
+    generalizationLineWidth: 3,
+    // 概要连线的颜色
+    generalizationLineColor: 'rgb(222, 101, 85)',
+    // 根节点样式
+    root: {
+      fillColor: 'rgb(207, 44, 44)',
+      color: 'rgb(255, 233, 157)',
+      borderColor: '',
+      borderWidth: 0,
+      fontSize: 24,
+      active: {
+        borderColor: 'rgb(255, 233, 157)',
+        borderWidth: 3,
+      }
+    },
+    // 二级节点样式
+    second: {
+      fillColor: 'rgb(255, 255, 255)',
+      color: 'rgb(211, 58, 21)',
+      borderColor: 'rgb(222, 101, 85)',
+      borderWidth: 2,
+      fontSize: 18,
+      active: {
+        borderColor: 'rgb(255, 233, 157)',
+      }
+    },
+    // 三级及以下节点样式
+    node: {
+      fontSize: 14,
+      color: 'rgb(144, 71, 43)',
+      active: {
+        borderColor: 'rgb(255, 233, 157)'
+      }
+    },
+    // 概要节点样式
+    generalization: {
+      fontSize: 14,
+      fillColor: 'rgb(255, 247, 211)',
+      borderColor: 'rgb(255, 202, 162)',
+      borderWidth: 2,
+      color: 'rgb(187, 101, 69)',
+      active: {
+        borderColor: 'rgb(222, 101, 85)'
+      }

+`simple-mind-map`目前支持四种结构：logicalStructure（逻辑结构图）、mindMap（思维导图）、organizationStructure（组织结构图）、catalogOrganization（目录组织图）、timeline（时间轴）、timeline2（时间轴2）、fishbone（鱼骨图）。
+
+可以在实例化`simple-mind-map`时通过选项指定使用的结构：
+
+```js
+new MindMap({

+# 如何渲染一个大纲
+
+思维导图本质就是一颗树，所以你可以使用树组件来完成大纲的显示。

+可以监听`data_change`事件来获取当前最新的思维导图数据：
+
+```js
+mindMap.on('data_change', (data) => {
+    // data数据是不带节点对象的纯数据
+    // 如果你需要操作节点对象，可以使用mindMap.renderer.renderTree
+    console.log(data, mindMap.renderer.renderTree)
+})
+```
+
+通常点击了大纲的某个节点，会将画布定位到该节点并激活该节点，这可以这么做：
+
+```js
+const node = data._node
+mindMap.renderer.moveNodeToCenter(node)

+```
+
+当在大纲树上编辑了某个节点的内容，需要同步到思维导图树上：

+# 如何渲染一个小地图
+
+> 要使用小地图需要注册小地图插件
+
+小地图可以方便看到当前画布可视区域在思维导图树的哪个部分。
+
+虽然小地图需要你自行开发，不过`simple-mind-map`提供了一些方法来帮你快速的完成这一工作。
+
+小地图由两部分组成，一个是当前的画布内容，一个是视口框，当缩放、移动、元素过多时画布上可能只显示了思维导图的部分内容，可以通过视口框来查看当前视口所在位置，以及可以通过在小地图上拖动来快速定位。
+
+当注册了小地图插件后可以通过`mindMap.miniMap`获取到插件实例，然后通过`mindMap.miniMap.calculationMiniMap`方法即可获取小地图渲染需要的数据，返回的数据结构如下：
+
+```js
+{
+      svgHTML, // 小地图html
+      viewBoxStyle, // 视图框的位置信息
+      miniMapBoxScale, // 视图框的缩放值
+      miniMapBoxLeft, // 视图框的left值
+      miniMapBoxTop, // 视图框的top值
+}
+```
+
+完整实现思路如下：
+
+1.准备一个宽高不为0的容器元素container，定位不为static
+
+2.在container内创建一个小地图容器元素miniMapContainer，绝对定位，设置变换中心点为`left top`：
+
+```css
+transform-origin: left top;
+```
+
+3.在container内创建一个视口框元素viewBoxContainer，绝对定位，设置边框样式，过渡属性（可选）
+
+4.监听data_change和view_data_change事件，最好也监听一下node_tree_render_end事件，防止初次渲染完毕后小地图没有刷新，在该事件内调用calculationMiniMap方法获取计算数据，然后将返回数据中的svgHTML渲染到miniMapContainer元素内，并且给miniMapContainer元素设置或更新如下样式：
+
+```js
+{
+    transform: `scale(${miniMapBoxScale})`,
+    left: miniMapBoxLeft + 'px',
+    top: miniMapBoxTop + 'px',
+}
+```
+5.将viewBoxStyle对象设置为viewBoxContainer元素的样式
+
+到这一步，当画布上的思维导图变化了，小地图也会实时更新，并且视口框元素会实时反映视口在思维导图图形上的位置
+
+6.监听container元素的mousedown、mousemove、mouseup事件，分别调用小地图插件实例的三个方法即可实现鼠标拖动时画布上的思维导图也随之拖动的效果
+
+插件的完整信息可以参考[miniMap](https://wanglin2.github.io/mind-map/#/doc/zh/miniMap)。

+    <h1>如何渲染一个小地图</h1>
+<blockquote>
+<p>要使用小地图需要注册小地图插件</p>
+</blockquote>
+<p>小地图可以方便看到当前画布可视区域在思维导图树的哪个部分。</p>
+<p>虽然小地图需要你自行开发，不过<code>simple-mind-map</code>提供了一些方法来帮你快速的完成这一工作。</p>
+<p>小地图由两部分组成，一个是当前的画布内容，一个是视口框，当缩放、移动、元素过多时画布上可能只显示了思维导图的部分内容，可以通过视口框来查看当前视口所在位置，以及可以通过在小地图上拖动来快速定位。</p>
+<p>当注册了小地图插件后可以通过<code>mindMap.miniMap</code>获取到插件实例，然后通过<code>mindMap.miniMap.calculationMiniMap</code>方法即可获取小地图渲染需要的数据，返回的数据结构如下：</p>
+<pre class="hljs"><code>{
+      svgHTML, <span class="hljs-comment">// 小地图html</span>
+      viewBoxStyle, <span class="hljs-comment">// 视图框的位置信息</span>
+      miniMapBoxScale, <span class="hljs-comment">// 视图框的缩放值</span>
+      miniMapBoxLeft, <span class="hljs-comment">// 视图框的left值</span>
+      miniMapBoxTop, <span class="hljs-comment">// 视图框的top值</span>
+}
+</code></pre>
+<p>完整实现思路如下：</p>
+<p>1.准备一个宽高不为0的容器元素container，定位不为static</p>
+<p>2.在container内创建一个小地图容器元素miniMapContainer，绝对定位，设置变换中心点为<code>left top</code>：</p>
+<pre class="hljs"><code><span class="hljs-attribute">transform-origin</span>: left top;
+</code></pre>
+<p>3.在container内创建一个视口框元素viewBoxContainer，绝对定位，设置边框样式，过渡属性（可选）</p>
+<p>4.监听data_change和view_data_change事件，最好也监听一下node_tree_render_end事件，防止初次渲染完毕后小地图没有刷新，在该事件内调用calculationMiniMap方法获取计算数据，然后将返回数据中的svgHTML渲染到miniMapContainer元素内，并且给miniMapContainer元素设置或更新如下样式：</p>
+<pre class="hljs"><code>{
+    <span class="hljs-attr">transform</span>: <span class="hljs-string">`scale(<span class="hljs-subst">${miniMapBoxScale}</span>)`</span>,
+    <span class="hljs-attr">left</span>: miniMapBoxLeft + <span class="hljs-string">&#x27;px&#x27;</span>,
+    <span class="hljs-attr">top</span>: miniMapBoxTop + <span class="hljs-string">&#x27;px&#x27;</span>,
+}
+</code></pre>
+<p>5.将viewBoxStyle对象设置为viewBoxContainer元素的样式</p>
+<p>到这一步，当画布上的思维导图变化了，小地图也会实时更新，并且视口框元素会实时反映视口在思维导图图形上的位置</p>
+<p>6.监听container元素的mousedown、mousemove、mouseup事件，分别调用小地图插件实例的三个方法即可实现鼠标拖动时画布上的思维导图也随之拖动的效果</p>
+<p>插件的完整信息可以参考<a href="https://wanglin2.github.io/mind-map/#/doc/zh/miniMap">miniMap</a>。</p>

+# 如何渲染一个右键菜单
+
+右键菜单可以方便的完成一些功能，大体上分两种，一是在画布上点击右键，二是在节点上点击右键，两者的功能肯定是不一样的，甚至根节点和其他节点功能上也有些不同，比如根节点不能添加同级节点，也不能被删除等等。
+
+右键菜单的UI界面需要你自行开发，可以设置成绝对定位或固定定位，然后让它显示在鼠标右键点击的位置即可。
+
+## 右键菜单的显示和隐藏
+
+首先监听`node_contextmenu`事件在右键点击节点时显示菜单：
+
+```js
+// 当前右键点击的类型
+const type = ref('')
+// 如果点击的节点，那么代表被点击的节点
+const currentNode = shallowRef(null)
+// 菜单显示的位置
+const left = ref(0)
+const top = ref(0)
+// 是否显示菜单
+const show = ref(false)
+
+mindMap.on('node_contextmenu', (e, node) => {
+    type.value = 'node'
+    left.value = e.clientX + 10
+    top.value = e.clientY + 10
+    show.value = true
+    currentNode.value = node
+})
+```
+
+你可以根据当前点击的节点来判断一些操作是否可用。比如根节点不能删除，不能插入同级节点，又比如同级第一个节点不能再被往上移，同级最后一个节点不能被往下移。
+
+对于画布的处理会比较麻烦，不能直接监听`contextmenu`事件，因为会和右键多选节点冲突，所以需要结合`mousedown`事件和`mouseup`事件来处理。
+
+```js
+// 记录鼠标右键按下的位置
+const mousedownX = ref(0)
+const mousedownY = ref(0)
+const isMousedown = ref(false)
+
+mindMap.on('svg_mousedown', (e) => {
+    // 如果不是右键点击直接返回
+    if (e.which !== 3) {
+        return
+    }
+    mousedownX.value = e.clientX
+    mousedownY.value = e.clientY
+    isMousedown.value = true
+})
+
+mindMap.on('mouseup', (e) => {
+    if (!isMousedown.value) {
+        return
+    }
+    isMousedown.value = false
+    // 如果鼠标松开和按下的距离大于3，则不认为是点击事件
+    if (
+        Math.abs(mousedownX.value - e.clientX) > 3 ||
+        Math.abs(mousedownX.value - e.clientY) > 3
+    ) {
+        hide()
+        return
+    }
+    type.value = 'svg'
+    left.value = e.clientX + 10
+    top.value = e.clientY + 10
+    show.value = true
+})
+```
+
+很简单，其实就是判断鼠标按下和松开的距离是否很小，是的话就认为是点击事件，否则应该是鼠标拖动。
+
+右键菜单显示了，肯定就需要隐藏，当左键点击了画布、左键点击了节点、左键点击了展开收起按钮时都需要隐藏右键菜单。
+
+```js
+const hide = () => {
+    show.value = false
+    left.value = 0
+    top.value = 0
+    type.value = ''
+}
+mindMap.on('node_click', hide)
+mindMap.on('draw_click', hide)
+mindMap.on('expand_btn_click', hide)
+```
+
+## 复制、剪切、粘贴的实现
+
+接下来介绍一下复制、剪切、粘贴的实现。
+
+一般来说你的右键菜单中肯定也会添加这三个按钮，另外快捷键操作也是必不可少的，但是这三个快捷键是没有内置的，所以你需要自己注册一下：
+
+```js
+mindMap.keyCommand.addShortcut('Control+c', copy)
+mindMap.keyCommand.addShortcut('Control+v', paste)
+mindMap.keyCommand.addShortcut('Control+x', cut)
+```
+
+如需删除调用`removeShortcut`方法即可。
+
+接下来实现一下这三个方法：
+
+```js
+// 保存复制/剪切的节点的数据，后续可以原来粘贴
+let copyData = null
+
+const copy = () => {
+    copyData = mindMap.renderer.copyNode()
+}
+
+const cut = () => {
+    mindMap.execCommand('CUT_NODE', _copyData => {
+        copyData = _copyData
+    })
+}
+
+const paste = () => {
+    mindMap.execCommand('PASTE_NODE', copyData)
+}
+```

+# 如何渲染富文本的悬浮工具栏
+
+> 要支持节点富文本编辑需要使用富文本插件
+
+如果开启了节点富文本编辑，那么可以对节点内的部分文本应用样式，一般当选中文本时上方会出现一个工具栏，有加粗、斜体、改变颜色等等的按钮。
+
+首先要监听`rich_text_selection_change`事件，也就是选中文本的事件：
+
+```js
+mindMap.on('rich_text_selection_change', (hasRange, rect, formatInfo) => {
+    // hasRange（是否存在选区）
+    // rectInfo（选区的尺寸和位置信息）
+    // formatInfo（选区的文本格式化信息）
+    // 显示你的工具栏
+})
+```
+
+可以通过`hasRange`来判断是否显示工具栏，工具栏的位置可以通过`rectInfo`获取，通过`formatInfo`可以获取当前选中文本的样式信息，比如已经被加粗了，那么你的加粗按钮就可以渲染为激活状态。
+
+### 工具栏定位
+
+```js
+let left = rect.left + rect.width / 2 + 'px'
+let top = rect.top - 60 + 'px'
+```
+
+计算出来的是相对于浏览器窗口左上角的位置，所以你的工具栏元素最好是添加在body元素下面，并且使用固定定位或相对定位，另外`z-index`的属性最好也设置的高一点，否则在弹窗等场景下可能会被挡住。
+
+### 加粗/取消加粗
+
+```js
+mindMap.richText.formatText({
+    bold: true/false
+})
+```
+
+### 斜体/取消斜体
+
+```js
+mindMap.richText.formatText({
+    italic: true/false
+})
+```
+
+### 下划线/取消下划线
+
+```js
+mindMap.richText.formatText({
+    underline: true/false
+})
+```
+
+### 删除线/取消删除线
+
+```js
+mindMap.richText.formatText({
+    strike: true/false
+})
+```
+
+### 设置字体
+
+```js
+mindMap.richText.formatText({
+    font: '宋体, SimSun, Songti SC'
+})
+```
+
+### 设置字号
+
+```js
+mindMap.richText.formatText({
+    font: 16 + 'px'
+})
+```
+
+### 设置文字颜色
+
+```js
+mindMap.richText.formatText({
+    color: '#fff'
+})
+```
+
+### 设置文字背景颜色
+
+```js
+mindMap.richText.formatText({
+    background: '#fff'
+})
+```
+
+### 清除样式
+
+```js
+mindMap.richText.removeFormat()
+```

+# 导入和导出
+
+## 导出
+
+> 要使用导出功能需要使用导出插件。
+
+目前支持导出为`.smm`、`.json`、`.svg`、`.png`、`.pdf`、`.md`文件。
+
+`.smm`是`simple-mind-map`自己定义的一种文件，其实就是`json`文件，换了一个扩展名而已。
+
+导出直接调用`export`方法即可。
+
+### 导出为smm、json
+
+这两种文件的导出是一样的：
+
+```js
+mindMap.export(type, isDownload, fileName, withConfig)
+```
+
+`withConfig`指定导出的数据中是否要包含节点数据外的配置数据，比如使用的布局、主题等，传`true`，导出的结构如下：
+
+```js
+{
+    layout,
+    root,
+    theme: {
+        template,
+        config
+    },
+    view
+}
+```
+
+如果传`false`，导出的数据只有`root`部分，也就是纯节点树。
+
+示例：
+
+```js
+mindMap.export('smm', true, '文件名', true)
+mindMap.export('json', true, '文件名', false)
+```
+
+### 导出为png、pdf
+
+导出这两种文件很简单：
+
+```js
+mindMap.export('png', true, '文件名')
+mindMap.export('pdf', true, '文件名')
+```
+
+### 导出为svg
+
+导出为`svg`可以传递的参数如下：
+
+```js
+mindMap.export(type, isDownload, fileName, plusCssText = '')
+```
+
+如果开启了节点富文本编辑，也就是`svg`中会存在节点的`html`结构，这就又存在一个问题，因为浏览器对每个元素默认会设置一些样式，影响最大的就是`margin`和`padding`，这就有可能会导致节点中的文字错位，所以可以通过`plusCssText`参数传入`css`样式：
+
+```js
+mindMap.export(
+    'svg', 
+    true, 
+    '文件名', 
+    false, 
+    `* {
+        margin: 0;
+        padding: 0;
+        box-sizing: border-box;
+    }`
+)
+```
+
+### 导出为md
+
+导出为`markdown`文件只要传递默认的三个参数即可：
+
+```js
+mindMap.export('md', true, '文件名')
+```
+
+## 导入
+
+目前支持从`.smm`、`.json`、`.xmind`、`.xlsx`、`.md`格式的文件导入。
+
+### 导入smm、json
+
+这两个文件导入很简单，直接读取文件内容，转成对象，然后调用相关方法渲染到画布即可。
+
+因为导出这两种类型时可以选择是否包含配置数据，所以导入的时候调用的方法也是不一样的：
+
+```js
+let data = JSON.parse('json数据')
+// 如果数据中存在root属性，那么代表是包含配置的完整数据，则使用setFullData方法导入数据
+if (data.root) {
+    mindMap.setFullData(data)
+} else {
+// 否则使用setData方法导入
+    mindMap.setData(data)
+}
+// 导入数据后有可能新数据渲染在可视区域外了，所以为了更好的体验，可以复位一下视图的变换
+mindMap.view.reset()
+```
+
+### 导入xmind
+
+要导入`xmind`文件，需要引入`xmind`的解析方法：
+
+```js
+import xmind from 'simple-mind-map/src/parse/xmind.js'
+```
+
+如果使用的是`umd`文件，可以这样获取：
+
+```js
+MindMap.xmind
+```
+
+如果你是通过`input type=file`等方式获取到的`File`文件对象，那么可以直接传递给`parseXmindFile`方法解析，注意返回的是一个`Promise`实例，会返回解析后的节点树数据，使用`setData`方法渲染到画布即可。
+
+```js
+let data = await xmind.parseXmindFile(file)
+mindMap.setData(data)
+```
+
+`.xmind`文件本质上是一个压缩包，改成`zip`后缀可以解压缩，里面存在一个`content.json`文件，如果你自己解析出了这个文件，那么可以把这个文件内容传递给这个`transformXmind`方法进行转换：
+
+```js
+let data = await xmind.transformXmind(fileContent)
+mindMap.setData(data)
+```
+
+另外如果导入的是`xmind8`版本的数据，需要使用`transformOldXmind`方法。
+
+### 导入xlsx
+
+这个文件的导入没有内置方法，需要你自己开发，以下是一个使用`xlsx`库的方式：
+
+```js
+import { read, utils } from 'xlsx'
+
+// 文件转buffer
+export const fileToBuffer = file => {
+  return new Promise(r => {
+    const reader = new FileReader()
+    reader.onload = () => {
+      r(reader.result)
+    }
+    reader.readAsArrayBuffer(file)
+  })
+}
+
+// File文件对象
+const transformXLSXToJson = async (file) => {
+    const wb = read(await fileToBuffer(file))
+    const data = utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]], {
+        header: 1
+    })
+    if (data.length <= 0) {
+        return
+    }
+    let max = 0
+    data.forEach(arr => {
+        if (arr.length > max) {
+        max = arr.length
+        }
+    })
+    let layers = []
+    let walk = layer => {
+        if (!layers[layer]) {
+        layers[layer] = []
+        }
+        for (let i = 0; i < data.length; i++) {
+        if (data[i][layer]) {
+            let node = {
+            data: {
+                text: data[i][layer]
+            },
+            children: [],
+            _row: i
+            }
+            layers[layer].push(node)
+        }
+        }

+    }
+
+    return layers[0][0]
+}
+
+let data = transformXLSXToJson('xlsx文件对象')
+mindMap.setData(data)
+```
+
+### 导入md
+
+要导入`markdown`文件需要引入相应的解析方法：
+
+```js
+import markdown from 'simple-mind-map/src/parse/markdown.js'
+```
+
+如果使用的是umd格式的文件，那么可以通过如下方式获取：
+
+```js
+MindMap.markdown
+```
+
+获取到`md`文件的内容后调用`transformMarkdownTo`方法转换即可，返回一个`Promise`实例：
+
+```js
+let data = await markdown.transformMarkdownTo('md文件内容')
+mindMap.setData(data)
+```

+    <h1>导入和导出</h1>
+<h2>导出</h2>
+<blockquote>
+<p>要使用导出功能需要使用导出插件。</p>
+</blockquote>
+<p>目前支持导出为<code>.smm</code>、<code>.json</code>、<code>.svg</code>、<code>.png</code>、<code>.pdf</code>、<code>.md</code>文件。</p>
+<p><code>.smm</code>是<code>simple-mind-map</code>自己定义的一种文件，其实就是<code>json</code>文件，换了一个扩展名而已。</p>
+<p>导出直接调用<code>export</code>方法即可。</p>
+<h3>导出为smm、json</h3>
+<p>这两种文件的导出是一样的：</p>
+<pre class="hljs"><code>mindMap.export(type, isDownload, fileName, withConfig)
+</code></pre>
+<p><code>withConfig</code>指定导出的数据中是否要包含节点数据外的配置数据，比如使用的布局、主题等，传<code>true</code>，导出的结构如下：</p>
+<pre class="hljs"><code>{
+    layout,
+    root,
+    <span class="hljs-attr">theme</span>: {
+        template,
+        config
+    },
+    view
+}
+</code></pre>
+<p>如果传<code>false</code>，导出的数据只有<code>root</code>部分，也就是纯节点树。</p>
+<p>示例：</p>
+<pre class="hljs"><code>mindMap.export(<span class="hljs-string">&#x27;smm&#x27;</span>, <span class="hljs-literal">true</span>, <span class="hljs-string">&#x27;文件名&#x27;</span>, <span class="hljs-literal">true</span>)
+mindMap.export(<span class="hljs-string">&#x27;json&#x27;</span>, <span class="hljs-literal">true</span>, <span class="hljs-string">&#x27;文件名&#x27;</span>, <span class="hljs-literal">false</span>)
+</code></pre>
+<h3>导出为png、pdf</h3>
+<p>导出这两种文件很简单：</p>
+<pre class="hljs"><code>mindMap.export(<span class="hljs-string">&#x27;png&#x27;</span>, <span class="hljs-literal">true</span>, <span class="hljs-string">&#x27;文件名&#x27;</span>)
+mindMap.export(<span class="hljs-string">&#x27;pdf&#x27;</span>, <span class="hljs-literal">true</span>, <span class="hljs-string">&#x27;文件名&#x27;</span>)
+</code></pre>
+<h3>导出为svg</h3>
+<p>导出为<code>svg</code>可以传递的参数如下：</p>
+<pre class="hljs"><code>mindMap.export(type, isDownload, fileName, plusCssText = <span class="hljs-string">&#x27;&#x27;</span>)
+</code></pre>
+<p>如果开启了节点富文本编辑，也就是<code>svg</code>中会存在节点的<code>html</code>结构，这就又存在一个问题，因为浏览器对每个元素默认会设置一些样式，影响最大的就是<code>margin</code>和<code>padding</code>，这就有可能会导致节点中的文字错位，所以可以通过<code>plusCssText</code>参数传入<code>css</code>样式：</p>
+<pre class="hljs"><code>mindMap.export(
+    <span class="hljs-string">&#x27;svg&#x27;</span>, 
+    <span class="hljs-literal">true</span>, 
+    <span class="hljs-string">&#x27;文件名&#x27;</span>, 
+    <span class="hljs-literal">false</span>, 
+    <span class="hljs-string">`* {
+        margin: 0;
+        padding: 0;
+        box-sizing: border-box;
+    }`</span>
+)
+</code></pre>
+<h3>导出为md</h3>
+<p>导出为<code>markdown</code>文件只要传递默认的三个参数即可：</p>
+<pre class="hljs"><code>mindMap.export(<span class="hljs-string">&#x27;md&#x27;</span>, <span class="hljs-literal">true</span>, <span class="hljs-string">&#x27;文件名&#x27;</span>)
+</code></pre>
+<h2>导入</h2>
+<p>目前支持从<code>.smm</code>、<code>.json</code>、<code>.xmind</code>、<code>.xlsx</code>、<code>.md</code>格式的文件导入。</p>
+<h3>导入smm、json</h3>
+<p>这两个文件导入很简单，直接读取文件内容，转成对象，然后调用相关方法渲染到画布即可。</p>
+<p>因为导出这两种类型时可以选择是否包含配置数据，所以导入的时候调用的方法也是不一样的：</p>
+<pre class="hljs"><code><span class="hljs-keyword">let</span> data = <span class="hljs-built_in">JSON</span>.parse(<span class="hljs-string">&#x27;json数据&#x27;</span>)
+<span class="hljs-comment">// 如果数据中存在root属性，那么代表是包含配置的完整数据，则使用setFullData方法导入数据</span>
+<span class="hljs-keyword">if</span> (data.root) {
+    mindMap.setFullData(data)
+} <span class="hljs-keyword">else</span> {
+<span class="hljs-comment">// 否则使用setData方法导入</span>
+    mindMap.setData(data)
+}
+<span class="hljs-comment">// 导入数据后有可能新数据渲染在可视区域外了，所以为了更好的体验，可以复位一下视图的变换</span>
+mindMap.view.reset()
+</code></pre>
+<h3>导入xmind</h3>
+<p>要导入<code>xmind</code>文件，需要引入<code>xmind</code>的解析方法：</p>
+<pre class="hljs"><code><span class="hljs-keyword">import</span> xmind <span class="hljs-keyword">from</span> <span class="hljs-string">&#x27;simple-mind-map/src/parse/xmind.js&#x27;</span>
+</code></pre>
+<p>如果使用的是<code>umd</code>文件，可以这样获取：</p>
+<pre class="hljs"><code>MindMap.xmind
+</code></pre>
+<p>如果你是通过<code>input type=file</code>等方式获取到的<code>File</code>文件对象，那么可以直接传递给<code>parseXmindFile</code>方法解析，注意返回的是一个<code>Promise</code>实例，会返回解析后的节点树数据，使用<code>setData</code>方法渲染到画布即可。</p>
+<pre class="hljs"><code><span class="hljs-keyword">let</span> data = <span class="hljs-keyword">await</span> xmind.parseXmindFile(file)
+mindMap.setData(data)
+</code></pre>
+<p><code>.xmind</code>文件本质上是一个压缩包，改成<code>zip</code>后缀可以解压缩，里面存在一个<code>content.json</code>文件，如果你自己解析出了这个文件，那么可以把这个文件内容传递给这个<code>transformXmind</code>方法进行转换：</p>
+<pre class="hljs"><code><span class="hljs-keyword">let</span> data = <span class="hljs-keyword">await</span> xmind.transformXmind(fileContent)
+mindMap.setData(data)
+</code></pre>
+<p>另外如果导入的是<code>xmind8</code>版本的数据，需要使用<code>transformOldXmind</code>方法。</p>
+<h3>导入xlsx</h3>
+<p>这个文件的导入没有内置方法，需要你自己开发，以下是一个使用<code>xlsx</code>库的方式：</p>
+<pre class="hljs"><code><span class="hljs-keyword">import</span> { read, utils } <span class="hljs-keyword">from</span> <span class="hljs-string">&#x27;xlsx&#x27;</span>
+
+<span class="hljs-comment">// 文件转buffer</span>

+# 如何持久化数据
+
+在线`demo`的数据是存储在电脑本地的，也就是`localStorage`里，当然，你也可以存储到数据库中。
+
+## 保存数据
+
+保存数据，一般有两种做法，一是让用户手动保存，二是当画布上的数据改变后自动保存，显然，第二中体验更好一点。
+
+要获取画布的数据，可以使用`getData`方法，可以传递一个参数，`true`指定返回的数据中包含配置数据，`false`指定只返回节点树数据。
+
+```js
+const data = mindMap.getData(true)
+```
+
+包含配置的完整数据结构：
+
+```js
+{
+    layout,
+    root,
+    theme: {
+        template,
+        config
+    },
+    view
+}
+```
+
+你可以直接把获取到的数据保存起来即可。
+
+如果要自动保存，那么肯定需要监听相关事件：
+
+```js
+this.$bus.$on('data_change', data => {
+    // 节点树数据改变
+    // data即完整数据中的root部分
+})
+this.$bus.$on('view_data_change', data => {
+    // 视图数据改变
+    // data即完整数据中的view部分
+})
+```
+
+主题和结构的改变一般是开发者提供一个ui界面让用户选择，所以可以自行触发保存。
+
+## 回显数据
+
+当从数据库获取到了保存的数据，那么怎么渲染到画布上呢，首先可以直接在`new`一个`MindMap`实例时直接传入：
+
+```js
+// 从数据中取出各个部分
+let { root, layout, theme, view } = storeData
+let mindMap = new MindMap({
+    el: container,
+    data: root,
+    layout: layout,
+    theme: theme.template,
+    themeConfig: theme.config,
+    viewData: view,
+    // ...
+})
+```
+
+其次如果是包含配置的完整数据也可以调用`setFullData`方法：
+
+```js
+mindMap.setFullData(data)
+```
+
+如果是纯节点数据可以调用`setData`方法：
+
+```js
+mindMap.setData(data)
+```
+
+修改结构可以调用`setLayout`方法：
+
+```js
+mindMap.setLayout(layout)
+```
+
+设置主题可以调用`setTheme`方法：
+
+```js
+mindMap.setTheme(theme)
+```
+
+设置主题配置可以调用`setThemeConfig`方法：
+
+```js
+mindMap.setThemeConfig(themeConfig)
+```
+
+设置视图数据可以调用`view.setTransformData`方法：
+
+```js
+mindMap.view.setTransformData(view)
+```
+

+    <h1>如何持久化数据</h1>
+<p>在线<code>demo</code>的数据是存储在电脑本地的，也就是<code>localStorage</code>里，当然，你也可以存储到数据库中。</p>
+<h2>保存数据</h2>
+<p>保存数据，一般有两种做法，一是让用户手动保存，二是当画布上的数据改变后自动保存，显然，第二中体验更好一点。</p>
+<p>要获取画布的数据，可以使用<code>getData</code>方法，可以传递一个参数，<code>true</code>指定返回的数据中包含配置数据，<code>false</code>指定只返回节点树数据。</p>
+<pre class="hljs"><code><span class="hljs-keyword">const</span> data = mindMap.getData(<span class="hljs-literal">true</span>)
+</code></pre>
+<p>包含配置的完整数据结构：</p>
+<pre class="hljs"><code>{
+    layout,
+    root,
+    <span class="hljs-attr">theme</span>: {
+        template,
+        config
+    },
+    view
+}
+</code></pre>
+<p>你可以直接把获取到的数据保存起来即可。</p>
+<p>如果要自动保存，那么肯定需要监听相关事件：</p>
+<pre class="hljs"><code><span class="hljs-built_in">this</span>.$bus.$on(<span class="hljs-string">&#x27;data_change&#x27;</span>, <span class="hljs-function"><span class="hljs-params">data</span> =&gt;</span> {
+    <span class="hljs-comment">// 节点树数据改变</span>
+    <span class="hljs-comment">// data即完整数据中的root部分</span>
+})
+<span class="hljs-built_in">this</span>.$bus.$on(<span class="hljs-string">&#x27;view_data_change&#x27;</span>, <span class="hljs-function"><span class="hljs-params">data</span> =&gt;</span> {
+    <span class="hljs-comment">// 视图数据改变</span>
+    <span class="hljs-comment">// data即完整数据中的view部分</span>
+})
+</code></pre>
+<p>主题和结构的改变一般是开发者提供一个ui界面让用户选择，所以可以自行触发保存。</p>
+<h2>回显数据</h2>
+<p>当从数据库获取到了保存的数据，那么怎么渲染到画布上呢，首先可以直接在<code>new</code>一个<code>MindMap</code>实例时直接传入：</p>
+<pre class="hljs"><code><span class="hljs-comment">// 从数据中取出各个部分</span>
+<span class="hljs-keyword">let</span> { root, layout, theme, view } = storeData
+<span class="hljs-keyword">let</span> mindMap = <span class="hljs-keyword">new</span> MindMap({
+    <span class="hljs-attr">el</span>: container,
+    <span class="hljs-attr">data</span>: root,
+    <span class="hljs-attr">layout</span>: layout,
+    <span class="hljs-attr">theme</span>: theme.template,
+    <span class="hljs-attr">themeConfig</span>: theme.config,
+    <span class="hljs-attr">viewData</span>: view,
+    <span class="hljs-comment">// ...</span>
+})
+</code></pre>
+<p>其次如果是包含配置的完整数据也可以调用<code>setFullData</code>方法：</p>
+<pre class="hljs"><code>mindMap.setFullData(data)
+</code></pre>
+<p>如果是纯节点数据可以调用<code>setData</code>方法：</p>
+<pre class="hljs"><code>mindMap.setData(data)
+</code></pre>
+<p>修改结构可以调用<code>setLayout</code>方法：</p>
+<pre class="hljs"><code>mindMap.setLayout(layout)
+</code></pre>
+<p>设置主题可以调用<code>setTheme</code>方法：</p>
+<pre class="hljs"><code>mindMap.setTheme(theme)
+</code></pre>
+<p>设置主题配置可以调用<code>setThemeConfig</code>方法：</p>
+<pre class="hljs"><code>mindMap.setThemeConfig(themeConfig)
+</code></pre>
+<p>设置视图数据可以调用<code>view.setTransformData</code>方法：</p>
+<pre class="hljs"><code>mindMap.view.setTransformData(view)
+</code></pre>
