app.js
//远程图片no found情况下指引 errImgFun:function (ev, that){ console.log("onImageError", ev); var _errImg = ev.target.dataset.errImg; var _errObj = {}; _errObj[_errImg] = "/img/00.jpg";//默认显示图片 that.setData(_errObj); },page页面
wxml:
<image src="{{item.WeChatPhoto}}" mode='widthFix' binderror="onImageError" data-err-img="seenote.seelist[{{index}}].WeChatPhoto"></image>//seenote.seelist[{{index}}].WeChatPhoto改成data里面数组中对应图片位置//binderror="onImageError"绑定图片加载错误事件js:
const app = getApp() // 远程图片加载404显示默认图 onImageError: function (ev) { //console.log("onImageError",ev); var _that = this; app.errImgFun(ev, _that); },
