从其它页面返回时 image 图片消失
发布于 6 年前 作者 xiayong 13413 次浏览 来自 官方Issues
  1. 在第一个页面显示一张图
  2. 跳转到另一个有很多图的页面,其中一张和第一个页面那张图地址相同
  3. 快速点击返回
  4. 第一个页面的图片消失

和返回的时机有一定关系,大致上是第二个页面的图开始加载,但还没有全加载出来的时候点返回,多试几次总能复现。在开发工具和安卓客户端都能重现,第二个页面图越多越容易重现。

开发工具重现视频:

安卓客户端重现视频:

第一个页面 /pages/index/index 代码:

<navigator url="/image/index">
  <image src="{{url}}"></image>
  <view>上面是图</view>
</navigator>
Page({
  data: {
    url'',
    list: [],
  },

  onLoad() {
    setTimeout(() => {
      this.setData({
        url'https://mszm.dtzhuanjia.com/image/team/mijuejubensha/logo.jpg',
      });
    }, 1000);
  },
})

第二个页面 /pages/image/index 代码:

<image src="{{url}}"></image>
<image wx:for="{{list}}" src="{{item}}"></image>
Page({
  data: {
    url'',
    list: [],
  },

  onLoad: function () {
    setTimeout(() => {
      this.setData({
        url'https://mszm.dtzhuanjia.com/image/team/mijuejubensha/logo.jpg',
        list: [
