微信小程序 官方文档对image 媒体组件加载失败 没有太多的解释,使用中出现了几个小问题,今天抽空记录一下
WXML:
<image class="userinfo-avatar" src="{{avatar}}" binderror="errorFunction"></image>
JS:
errorFunction: function(){ this.setData({ avatar: \'/image/head.png\' }) }WXML:
<view wx:for="{{branchList}}" wx:key="{{key}}" wx:for-index=\'index\'> <image src=\'{{item.branch_photo}}\' binderror="errorFunction" data-index=\'{{index}}\'></image> </view>errorFunction: function (event) { console.log(event) var index = event.currentTarget.dataset.index var img = \'branchList[\'+index+\'].branch_photo\' this.setData({ [img]: \'/pages/resource/img/loading.gif\' }) }
