Solve the problem that after the inner page is shared, the user cannot return to the home page through the shared page
The essence is to set a variable isshare to determine whether it is entered in the sharing page
data setting
Page({
data: {
isShare : false, //标识是否是从分享进入的小程序
/*
*下面写你自己需要的其他变量
*/
},
onLoad(options) {
//如果是从分享页面进入，则修改标识
if(options.isshare == 1){
this.setData({
isShare : true
})
}
},
/* 分享给朋友 */
onShareAppMessage() {
return {
title: '这里写上分享的文案！',
path: 'pages/report/report?isshare=1' //这里写当前页面的路径，后面带上参数isshare=1
}
},
/* 分享至朋友圈 */
onShareTimeline(){
return{
title: '这里写上分享的文案！',
path: 'pages/report/report?isshare=1'
}
},
/*
*返回上一级页面
*因为分享出去的页面，没有带上一级页面，所以不能直接返回
*/
BackPage() {
wx.navigateBack({
delta: 1
})
},
/* 分享页面的返回按钮，实际上是关闭其他页面，直接打开首页 */
toHome() {
wx.reLaunch({
url: '/pages/index/index'
})
},
/* 其他代码 */
})wxml
<image bindtap="{
{isShare? 'toHome':'BackPage'}}" class='d-back-home' src='http://cdn.xcx.pemarket.com.cn/icon-Return%20to%20the%20home%20page.png' lazy-load></image>

/* 返回按钮,固定定位,悬浮 */
.d-back-home {
position: fixed;
width: 96rpx;
height: 96rpx;
right: 30rpx;
bottom: 166rpx;
z-index: 10000;
}
Explanation: In the actual development, I made some packaging for the back button. The above code is just to illustrate the problem, not the actual code of the rendering.
