在uni-app开发中，开发一个资讯详情页面，详情里包含图片和代码块。这时候用简单的rich-text控件已经不够用了。用官方demo里的html-parser.js也无法很好的展示代码区域。这个时候就要使用官方提供的插件来解决。

官方的这个插件有很多问题。需要使用第3方修复的版本：https://ext.dcloud.net.cn/plugin?id=1279

首先：下载插件 ：https://ext.dcloud.net.cn/plugin?id=1279

第二步：写代码 demo示例

<template>
  <div>
    <u-parse :content="content" @navigate="navigate"></u-parse>
  </div>
</template>
 
<script>import uParse from "@/components/feng-parse/parse.vue";  //注意：官方提供的示例代码有问题
 
export default {
  components: {
    uParse
  },
  data () {
    return {
      article: '<div>我是HTML代码</div>'
    }
  },
  methods: {
    preview(src, e) {
      // do something
    },
    navigate(href, e) {
      // do something
    }
  }
}
</script>
 
<style>
@import url("../../components/feng-parse/parse.css");  //注意：官方提供的示例代码有问题
</style>

我这边具体的业务代码如下：（可以忽略）

<template>
    <view>
        <view class="banner">
            {{article_detail.title}}
        </view>

        <view class="article-meta">
            <text class="article-meta-text article-author">作者：{{article_detail.fields.author}}</text>
        </view>
        <view class="article-content">

            <div>
                <u-parse :content="article_detail.content" @preview="preview" @navigate="navigate" />
            </div>
            <view class="parse-con">
                <u-parse :content="article_detail.content" @navigate="navigate"></u-parse>
            </view>

            <view v-if="article_detail.fields.source" class="article-source">
                文章来自：{{article_detail.fields.source}}
            </view>
        </view>
        <view class="comment-wrap"></view>
    </view>
</template>


<script>
    import uParse from "@/components/feng-parse/parse.vue"

    const FAIL_CONTENT = '<p>数据加载中</p>';
    export default {

        data() {
            return {

                article_detail: {},

            }
        },
        onShareAppMessage() {
            return {
                title: this.article_detail.title,
                path: '/pages/detail/detail?query=' + this.id
            }
        },
        onLoad: function(event) {
            // 目前在某些平台参数会被主动 decode，暂时这样处理。
            try {
