vue3自定义路由栈pinia+vue-router来实现

我们知道vue-router使用push跳转可以通过浏览器的返回箭头，就能回到上一页，是因为它有路由栈，每次跳转都会存放（记录）当前路由的相关信息。

根据这个思路我们利用pinia+vue-router 来自定义路由栈。

说下项目中自定义路由栈的使用场景：

用vue开发的h5移动端网页使用router自带的push跳转会导致苹果手机底部出现左右返回箭头，为了美观和方便布局不想要自带的箭头，只能使用replace跳转。但是replace跳转有多个页面想要每次返回上一页的时候带上原有的路由参数，就不好记录带参数上了，于是决定自己定义一套路由栈只用replace跳转同样能记录到每个页面的参数，正常的返回上一页。

store/routerStore.ts 代码：

import { defineStore } from 'pinia'
import { reactive, toRefs } from 'vue'
import router from '@/router'

export const useRouterStore = defineStore('routerStore', () => {
  const state: any = reactive({
    routerInn: [],
    // 清理路由
    routerBackFun: (num = 1) => {
      if (typeof num !== 'number') {
        num = 1
      }
      // 清除当前路由栈，回到上一栈
      if (state.routerInn?.length && state.routerInn[state.routerInn.length - num].backPath) {
        const routerInnBack = { ...state.routerInn[state.routerInn.length - num] }
        if (num) {
          state.routerInn.length -= num
        }
        router.replace({
          path: routerInnBack.backPath,
          query: routerInnBack.backQuery
        })
      }
    },
    // 添加路由
    routerGoFun: (type, path = '', query, backPath, backQuery = '') => {
      // backQuery 不传形参时 默认值 undefined
      if (type === 'routerInnPush') {
        const routerInnItem = {
          backQuery,
          backPath,
          path,
          query
        }
        state.routerInn.push(routerInnItem)
      }
      // 别的标识则不记录-直接跳转
      router.replace({
        path,
        query
      })
    }
  })

  return {
    ...toRefs(state)
  }
}, {
  // 持久化配置
  persist: {
    key: 'routerStore',
    // 修改为 sessionStorage，默认为 localStorage
    storage: sessionStorage,
  },
})

home/index.vue 代码：

<template>
  <div class="home">
    <div style="background-color: pink;color: #fff;">=测试=自定义路由栈</div>
    <button @click="routerStore.routerGoFun('routerInnPush','/lx',{title: 'home say:你好'},'/')">跳转到练习页</button>
  </div>
</template>

<script name="Home" lang="ts" setup>
import { onMounted, } from 'vue'
import { useRouterStore } from '@/store/routerStore'
// 'routerInnPush'
const routerStore = useRouterStore()

onMounted(() => {
  //
})
</script>

<style lang="css" scoped>
.home {
  color: pink;
  font-size: 16px;
}
</style>

home/Lx.vue 代码：

<template>
  <div style="font-size: 14px;">
    <div>Lx页</div>
    <br>
    <div>传参：{{ route.query.title }}</div>
    <br>
    <button @click="routerStore.routerGoFun('routerInnPush','/lxb',{title: 'lx say: 你好啊'},route.path,route.query)">跳转到练习b页面</button>
    <br>
    <br>
    <button @click="routerStore.routerBackFun">返回上一页</button>
  </div>
</template>

<script lang="ts" setup>
import { useRouterStore } from '@/store/routerStore'
import { useRoute } from 'vue-router'
const routerStore = useRouterStore()
const route = useRoute()
</script>

home/Lxb.vue 代码：

<template>
  <div style="font-size: 14px;">
    <h2>我是练习b{{ route?.params?.title }}页面</h2>
    <div>传参：{{ route.query.title }}</div>
    <button @click="routerStore.routerBackFun">返回上一页</button>
  </div>
</template>

<script lang="ts" setup>
import { useRouterStore } from '@/store/routerStore'
import { useRoute } from 'vue-router'
const routerStore = useRouterStore()
const route = useRoute()
</script>
