-
-查看 [功能介绍](https://jin-yufeng.gitee.io/mp-html/#/overview/feature) 了解更多
-
-## 使用方法
-- `uni_modules` 方式
- 1. 点击右上角的 `使用 HBuilder X 导入插件` 按钮直接导入项目或点击 `下载插件 ZIP` 按钮下载插件包并解压到项目的 `uni_modules/mp-html` 目录下
- 2. 在需要使用页面的 `(n)vue` 文件中添加
- ```html
-
-
- ```
- ```javascript
- export default {
- data() {
- return {
- html: 'Hello World!
'
- }
- }
- }
- ```
- 3. 需要更新版本时在 `HBuilder X` 中右键 `uni_modules/mp-html` 目录选择 `从插件市场更新` 即可
-
-- 源码方式
- 1. 从 [github](https://github.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 或 [gitee](https://gitee.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 下载源码
- 插件市场的 **非 uni_modules 版本** 无法更新，不建议从插件市场获取
- 2. 在需要使用页面的 `(n)vue` 文件中添加
- ```html
-
- ```
- ```javascript
- import mpHtml from '@/components/mp-html/mp-html'
- export default {
- // HBuilderX 2.5.5+ 可以通过 easycom 自动引入
- components: {
- mpHtml
- },
- data() {
- return {
- html: 'Hello World!
'
- }
- }
- }
- ```
-
-- npm 方式
- 1. 在项目根目录下执行
- ```bash
- npm install mp-html
- ```
- 2. 在需要使用页面的 `(n)vue` 文件中添加
- ```html
-
- ```
- ```javascript
- import mpHtml from 'mp-html/dist/uni-app/components/mp-html/mp-html'
- export default {
- // 不可省略
- components: {
- mpHtml
- },
- data() {
- return {
- html: 'Hello World!
'
- }
- }
- }
- ```
- 3. 需要更新版本时执行以下命令即可
- ```bash
- npm update mp-html
- ```
-
- 使用 *cli* 方式运行的项目，通过 *npm* 方式引入时，需要在 *vue.config.js* 中配置 *transpileDependencies*，详情可见 [#330](https://github.com/jin-yufeng/mp-html/issues/330#issuecomment-913617687)
- 如果在 **nvue** 中使用还要将 `dist/uni-app/static` 目录下的内容拷贝到项目的 `static` 目录下，否则无法运行

-## 插件扩展
-除基本功能外，本组件还提供了丰富的扩展，可按照需要选用
-
-| 名称 | 作用 |
-|:---:|---|
-| audio | 音乐播放器 |
-| editable | 富文本 **编辑**（[示例项目](https://mp-html.oss-cn-hangzhou.aliyuncs.com/editable.zip)） |

-
-从插件市场导入的包中 **不含有** 扩展插件，使用插件需通过微信小程序 `富文本插件` 获取或参考以下方法进行打包：
-1. 获取完整组件包
- ```bash
- npm install mp-html
- ```
-2. 编辑 `tools/config.js` 中的 `plugins` 项，选择需要的插件
-3. 生成新的组件包
- 在 `node_modules/mp-html` 目录下执行
- ```bash
- npm install
- npm run build:uni-app
- ```
-4. 拷贝 `dist/uni-app` 中的内容到项目根目录
-
-查看 [插件](https://jin-yufeng.gitee.io/mp-html/#/advanced/plugin) 了解更多
-
-## 关于 nvue
-`nvue` 使用原生渲染，不支持部分 `css` 样式，为实现和 `html` 相同的效果，组件内部通过 `web-view` 进行渲染，性能上差于原生，根据 `weex` 官方建议，`web` 标签仅应用在非常规的降级场景。因此，如果通过原生的方式（如 `richtext`）能够满足需要，则不建议使用本组件，如果有较多的富文本内容，则可以直接使用 `vue` 页面
-由于渲染方式与其他端不同，有以下限制：
-1. 不支持 `lazy-load` 属性
-2. 视频不支持全屏播放
-3. 如果在 `flex-direction: row` 的容器中使用，需要给组件设置宽度或设置 `flex: 1` 占满剩余宽度
-
-纯 `nvue` 模式下，[此问题](https://ask.dcloud.net.cn/question/119678) 修复前，不支持通过 `uni_modules` 引入，需要本地引入（将 [dist/uni-app](https://github.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 中的内容拷贝到项目根目录下）
