公众号菜单栏跳转到小程序穿参数

原創 愚蠢地人类 2020-06-02 17:33
现在公众号菜单添加的小程序页面路径，可以带参数，
例如页pages/index/index?id=99

也就是说可以通过菜单跳转到小程序任意页面。



但是这里面有个坑：如果你想跳转到tabbar界面，那么是不能传参数的，只能单纯到跳转到界面，和小程序内部的跳转一样（wx.switchTo)

如果想跳转到小程序tabbar界面并且带参数：解决方案

    在app.json文件中新建一个路径，例如新建"pages/menuBack/menuBack",这个时候我们在pages/menuBack/menuBack.js这个js文件中的onLoad 函数中让他跳转到你想要跳转到界面，这个时候你可能会问，还是跳转到tabbar界面，所以依旧不能带参数啊，

    我们可以在页/ menuBack / menuBack这个界面设置个全局变量app.globalData.xxx，然后在你想到跳转的界面判断这个全局变量是否存在再去做相应的处理
