1. wxParse简介

wxParse 是一个微信小程序富文本解析组件,支持支持Html及markdown转wxml。

wxParse gitHub地址:https://github.com/icindy/wxParse

目前项目已停止维护了,原因未知。

使用wxParse在微信小程序里加载此富文本:

2. wxParse应用

2.1. js

const WxParse = require('../../utils/wxParse/wxParse.js')

Page({
data: {

},

    onLoad() {
        var article = this.data.content.replace(/&quot;/g, '');;
        var that = this;
        WxParse.wxParse('article', 'html', article, that, 5);
    }
})

2.2. html

<import src="../../utils/wxParse/wxParse.wxml"/>

<view class="wxParse">
    <template is="wxParse" data="{{wxParseData:article.nodes}}"/>
</view>

2.3. css

@import "../../utils/wxParse/wxParse.wxss";

2.4. 显示效果

在小程序里的显示效果如下:

2.5. 注意

  • 富文本字符串中不应该有一些特殊字符,例如&quot;
  • 如果加载富文本html,当字符串显示了出来,那一般就是富文本字符串中包含了一些特殊字符,电脑浏览器可能识别,在微信小程序上会加载不出来;
  • 在加载富文本的时候,去掉&quot;即可。
let content = fishPublishInfo.content.replace(/&quot;/g, '');
WxParse.wxParse('article', 'html', content, this, 5);
