navigateLastTo
refresh
wx.switchTab switchTab
wx.redirectTo redirectTo
wx.reLaunch reLaunch

Feature

  1. router interceptor

  2. new API

  3. deal with the max count of weixin miniapp page stack

  4. when target page is repeated sequential, navigateBack、navigateBackTo、navigateLastTo will merge them

  5. auto deal tabBar page

  6. better performance and code experience

install

require ./dist/wx-nav.cjs.js or ./dist/wx-nav.esm.js.

or use npm or yarn:

npm i --save wx-nav

yarn add wx-nav

Usage

// src/utils/wxnav.js
import WxNav from "wx-nav"

export const {
  navigateTo,
  navigateBack,
  navigateBackTo,
  navigateLastTo,
  refresh,
  switchTab,
  redirectTo,
  reLaunch
} = new WxNav({
  // optional. default value 10. max length of page stack.
  maxStack: 10,
  // optional. for `refresh()` or `switchTab(pageAlias)`
  tabBarPages: {
    // pageAlias: pageRoute
    home: "pages/home/main",
    userCenter: "pages/userCenter/main"
  },
  // optional
  beforeEach(to, from, next, apiName){
    next()
  },
  // optional
  afterEach(to, from, apiName){}
})

// index.vue
goToNextPage(){
  navigateTo("pages/nextpage/main", {from: "home"}, (isSuccess) => {
    if(!isSuccess){
      console.log("navigateTo fail")
    }
  })
}

API

navigateTo

navigateTo(url [, query [, cb]]) navigateTo(url [, cb])

  • url: string.
  • query: object. like {a:b, c:d} will be transform to ${url}?a=b&c=d.
  • cb: function. optional. receive a boolean value that mark the function call success or fail.

like wx.navigateTo, but navigateTo will use redirectTo instead when current pages length is MAX_PAGES_LENGTH.

navigateBack

navigateBack(delta ,cb) navigateBack(cb) navigateBack()

  • delta: integer. default value is 1.

like wx.navigateBack, but navigateBack() will check the target url whether repeat sequential or not. if page stack is [A, B, C, C, C, D], navigateBack() will be back to page C, stack is [A, B, C].

navigateBackTo

navigateBackTo(url [, cb])

navigateBackTo(url) will find the latest url page in page stack, and back to the page. there is also check url whether repeat sequential or not. if url is repeated, back to the earlist url. if page stack is [A, B, C, C, C, D, E, F], navigateBackTo(C) will be back to page C, stack is [A, B, C].

navigateLastTo

navigateLastTo(url [, cb])

navigateLastTo(url) assert last page is url, and back to url。

  1. if last page is url and repeat: page stack is [A, B, C, C, C, D], navigateLastTo(C) will change page stack to [A, B, C]。
  2. if last page is not url，there is call redirectTo(url) inside。 page stack is [A, B, C, D], navigateLastTo(C) will cahnge page stack to [A, B, C]. page stack is [A, B, C, D], navigateLastTo(D) will change page stack to [A, B, C, D], current page D will refresh。

refresh

refresh(cb) refresh()

refresh current page, such as TabBar page.

switchTab

switchTab(target [, cb])

  • target: string. url or alias of url. why there doesn't support query? see official document

redirectTo

redirectTo(url [, query [, cb]]) redirectTo(url [, cb])

reLaunch

reLaunch(url [, query [, cb]]) reLaunch(url [, cb])

it's better perfermance than wx.reLaunch.
