微信小程序获取rich-text（富文本）渲染内容高度，rich-text（富文本）里img 样式设置

1.背景：

在某些场景下，例如在某些详细信息内容展示数据量特别大的时候（有时候特别小），当数据量特别大的时候，需要做展示固定高度，展开更多内容完全展示，收起内容又还原。当内容特别少的时候，例如小于3行，不展示更多按钮。（小程序内容获取的时候是不能知道当前内容有几行的，可能有人会说，我知道字体大小一行内放几个字，几行就再乘以几，让后台算好，传两个字段，展开收起，分别用两个字段即可，理论上是可行的（但太麻烦，如果有图片有文字呢，这种思路就歇菜了））。其实前端在渲染的时候也不知道有几行，但可以获取内容高度，通过内容高度进行比较即可。

style="text-indent: 28px;"><strong><span>3、地价是重要参考因素</span></strong></p><p style="text-indent: 28px;"><span>土拍市场火热！若区域地王一出，周边楼盘立马放风要涨价，至于最终的结果，能不能成功，请参照第一条。</span></p><p style="text-indent:

3.说明

3.1 清除图片默认样式用这段

/**
     * 1.请求来的富文本内容的img有自身的一些宽高属性，宽度可能都超过屏幕最大宽了;
     * 2.为了正常展示图片文本不错乱，需要将内容处理;
     * 3.正则是一个好东西（下边有一段正则匹配）

     * **/
    var content_new = content.replace(/<img([\s\w"-=\/\.:;]+)((?:(height="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)((?:(width="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)((?:(height="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)((?:(style="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)((?:(class="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)((?:(alt="[^"]+")))/ig, '<img$1')
      .replace(/<img([\s\w"-=\/\.:;]+)/ig, '<img$1 ')
      .replace(/\<img/gi, '<img class="rich-img" ');

3.2在获取容器高度，和所需高度对比时，需要用到延时器，当内容量比较大时，获取的高度会不准确：

that.setData({
      rich: content_new
    }, () => {
      /**
       * 虽然变为同步的了，但是如果涉及数据量比较大的情况，计算高度还是不会特别准确
       * **/
      setTimeout(function () {
      var query = wx.createSelectorQuery();
      // 获取设备信息，通过宽高比计算当前机型的限制高度
      wx.getSystemInfo({
        success: (res) => {
          var radito = res.windowWidth / 375;
          var height_my = 1000 * radito / 2;
          // 通过获取当前dom节点的高度和所需的高度对比，如果高了就展示下拉，否则不展示
          query.select('#richText-rich').boundingClientRect(function (rect) {
            // console.log('rect', rect)
            // console.log('height_my', height_my)
            // console.log('height_my < rect.height', height_my < rect.height)
            if (height_my < rect.height) {
              that.setData({
                sjFlag: 1
              });
            }
          }).exec();
        },
      });
      }, 300);

    });
