@icindy wxParse.js文件中的图片点击事件wxParseImgTap，图片点击后报错： WAService.js:3 thirdScriptError Cannot read property 'imageUrls' of undefined;at "pages/page/index" page wxParseImgTap function TypeError: Cannot read property 'imageUrls' of undefined 修复： ` /**

• 主函数入口区 **/ function wxParse(bindName = 'wxParseData', type='html', data='
  数据不能为空
  ', target,imagePadding) { var that = target; var transData = {};//存放转化后的数据 if (type == 'html') { transData = HtmlToJson.html2json(data, bindName); console.log(JSON.stringify(transData, ' ', ' ')); } else if (type == 'md' || type == 'markdown') { var converter = new showdown.Converter(); var html = converter.makeHtml(data); transData = HtmlToJson.html2json(html, bindName); console.log(JSON.stringify(transData, ' ', ' ')); } transData.view = {}; transData.view.imagePadding = 0; if(typeof(imagePadding) != 'undefined'){ transData.view.imagePadding = imagePadding } var bindData = {}; bindData[bindName] = transData; that.setData(bindData); that.bindData = bindData; // 增加这一行代码 that.wxParseImgLoad = wxParseImgLoad; that.wxParseImgTap = wxParseImgTap; } // 图片点击事件 function wxParseImgTap(e) { var that = this; var nowImgUrl = e.target.dataset.src; var tagFrom = e.target.dataset.from; if (typeof (tagFrom) != 'undefined' && tagFrom.length > 0) { wx.previewImage({ current: nowImgUrl, // 当前显示图片的http链接 // urls: that.data[tagFrom].imageUrls // 需要预览的图片http链接列表 urls: that.bindData[tagFrom].imageUrls // 注释掉上面的 换着一行 }) } }`

@icindy
在wxParse.js 的第50行后面增加：that.bindData = bindData; // 增加这一行代码 在wxParse.js 的wxParseImgTap方法中将urls换成：urls: that.bindData[tagFrom].imageUrls // 注释掉上面的 换着一行
