微信小程序的src图片加载多张就不渲染

  <view wx:if="{{item.commentPics.length>0}}">
            <image src="{{item.commentPics}}" data-list='{{item.commentPics}}' data-src="{{item.commentPics}}" bindtap="imgOpen" data-index='{{index}}' mode="aspectFill"/>
          </view> 

//图片点击预览事件
 imgOpen: function (e) {
   var src = e.currentTarget.dataset.src;//获取data-src
   var imgList = e.currentTarget.dataset.list;//获取data-list
   var str = ""; 
   var newArr = [];
   str = src + "," + imgList 
   console.log(str)
   newArr = str.split(',')

wx.previewImage({
  current: newArr,
  urls:newArr,
  success: function(res) {

  },
}) 
 },

图片没做循环获取吧

var src = e.currentTarget.dataset.src;//获取data-src
var imgList = e.currentTarget.dataset.list;//获取data-list

图片加上 bindload 事件
