|
||||
|
||||
## 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
|
||||
<!-- 不需要引入，可直接使用 -->
|
||||
<mp-html :content="html" />
|
||||
```
|
||||
```javascript
|
||||
export default {
|
||||
data() {
|
||||
return {
|
||||
html: '<div>Hello World!</div>'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
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
|
||||
<mp-html :content="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: '<div>Hello World!</div>'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- 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
|
||||
<mp-html :content="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: '<div>Hello World!</div>'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
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

|
||||
|
||||
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）

## 使用方法
|
||||
### 原生平台
|
||||
- `npm` 方式
|
||||
1. 在项目目录下安装组件包
|
||||
|
||||
```bash
|
||||
npm install mp-html
|
||||
```
|
||||
2. 开发者工具中勾选 `使用 npm 模块`（若没有此选项则不需要）并点击 `工具 - 构建 npm`
|
||||
3. 在需要使用页面的 `json` 文件中添加
|
||||
|
||||
```json
|
||||
{
|
||||
"usingComponents": {
|
||||
"mp-html": "mp-html"
|
||||
}
|
||||
}
|
||||
```
|
||||
4. 在需要使用页面的 `wxml` 文件中添加
|
||||
|
||||
```html
|
||||
<mp-html content="{{html}}" />
|
||||
```
|
||||
5. 在需要使用页面的 `js` 文件中添加
|
||||
|
||||
```javascript
|
||||
Page({
|
||||
onLoad () {
|
||||
this.setData({
|
||||
html: '<div>Hello World!</div>'
|
||||
})
|
||||
}
|
||||
})
|
||||
```
|
||||
- 源码方式
|
||||
1. 将源码中对应平台的代码包（`dist/platform`）拷贝到 `components` 目录下，更名为 `mp-html`
|
||||
2. 在需要使用页面的 `json` 文件中添加
|
||||
|
||||
```json
|
||||
{
|
||||
"usingComponents": {
|
||||
"mp-html": "/components/mp-html/index"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
