几行代码解决你的问题：
<view class="bg-img" wx:for="{{ImgFileIDList}}" wx:key="index" > <image lazy-load="true" mode='aspectFill' src="{{item}}" data-index="{{index}}" bindtap="ViewImage"/> </view> //js代码 //展示预览图片 ViewImage(e) { let index = e.currentTarget.dataset.index //ImgFileIDList为自己要展示图片的数组 let imgAry = this.data.ImgFileIDList wx.previewImage({ urls: imgAry, current: imgAry[index] }) },previewImage里面的urls参数应该是数组，是你待预览的图片的数组，比如
['sss.com/xxx1.jpg','sss.com/xxx2.jpg'....]这个设置对了你的问题就解决了

<view class="blockDiv" ><view class="block" wx:for="{{imgUrl}}" wx:key="imgUrl"><image bindtap = "clickImg" class="bdimg" mode='aspectFill' lazy-load='true' src="{{imgUrl[index]}}"></image></view></view>-------------------------------------------------------------clickImg: function(e) {console.log("xxxxxxxxxxx")var imgUrl = this.data.imgUrl;var current = e.target.dataset.src;wx.previewImage({urls: imgUrl,current: current,})},另外，你可以直接用item代替imgUrl[index]
wx:key="*this"
因为你js里有这一句，所以wxml里要有对应的data-src，不然js里的e.target.dataset.src为空的
