Wechat applet page Jump

Wechat applet has prepared a lot of for page Jump API, We can call different... In different situations API, Let me briefly introduce the common methods of page Jump .

1,navigateBack

Jump to the previous page . If there is now A,B Two pages , At first we were A page , And then we passed A Some operations of the page directly enter B page , At this time, we also want to start from B The page goes back to A page , It can be used directly navigateBack; Not only that, we can also return to his multi-level superior page , Just join A,B,C Three pages from A Direct to B, from B Direct to C, We can use this method directly from C Page jumps back to A or B page

wx.navigateBack({
    
	delta:1// Go back to the previous page 
	//delta:2 // Return to the previous second page 
})

2,navigateTo

Jump from one page to another , But you can't jump to tabBer page

wx.navigateTo({
    
	url:" Page address "
})

3,switchTab

Jump to app.json Registered TabBer page

wx.switchTab({
    
  url: 'page/index/index'
})

What we're talking about here is just our common way of centralized page Jump , But in the implementation of page Jump （ If used wx.navigateTo） When you do a page Jump , We will find that if the page we want to jump to is not under the same package, we will report an error and can't find the page

Let's explain here that we use wx.navigateTo When performing page Jump, it is in URL Address where he will automatically add the location of the current page before the jump address you write . This is sometimes inconvenient , So we can not write the address of the target address directly , The location of the target page can be represented in the following way

The first two points indicate going back to the previous folder , The following name indicates a package or a page under the page folder , above URL Express , First go back to the folder where this page is stored , And find the folder named index The file of , And in finding index The file named index.wxml The file of
I suggest we write a jump page URL You can jump to the address in the following way , It's safer
