微信小程序 解决内层页面分享出去后 用户无法通过分享页面返回首页问题
本质就是设置一个变量isshare来判断是否是分享页面中进入的
data设置
isshare: 0,//不是分享页面进入
js
onShareAppMessage: function () {return {title: 'xxx',path: 'pages/MyPages/my_detail/my_detail?isshare=1&&id=' + this.data.id}},backHome: function () {wx.reLaunch({url: '/pages/home/home-index/home-index'})}
onload
if (options.isshare == 1) {console.log('是分享进入');this.setData({'isshare': options.isshare})}
wxml
<image wx:if="{{isshare}}" bindtap='backHome' class='d-back-home' src='http://cdn./icon-Return%20to%20the%20home%20page.png' lazy-load></image>
css
/* 回到首页,固定定位,悬浮 */.d-back-home {position: fixed;width: 96rpx;height: 96rpx;right: 30rpx;bottom: 166rpx;z-index: 10000;}
