公衆號菜單欄跳轉到小程序穿參數

原創 愚蠢地人类 2020-06-02 17:33
現在公衆號菜單添加的小程序頁面路徑，可以帶參數，
例如頁pages/index/index?id=99

也就是說可以通過菜單跳轉到小程序任意頁面。



但是這裏面有個坑：如果你想跳轉到tabbar界面，那麼是不能傳參數的，只能單純到跳轉到界面，和小程序內部的跳轉一樣（wx.switchTo)

如果想跳轉到小程序tabbar界面並且帶參數：解決方案

    在app.json文件中新建一個路徑，例如新建"pages/menuBack/menuBack",這個時候我們在pages/menuBack/menuBack.js這個js文件中的onLoad 函數中讓他跳轉到你想要跳轉到界面，這個時候你可能會問，還是跳轉到tabbar界面，所以依舊不能帶參數啊，

    我們可以在頁/ menuBack / menuBack這個界面設置個全局變量app.globalData.xxx，然後在你想到跳轉的界面判斷這個全局變量是否存在再去做相應的處理
