vue-router路由传参

tip: 用params传参，F5强制刷新参数会被清空，用query，由于参数适用路径传参的所以F5强制刷新也不会被清空。（传参强烈建议适用string）

也可以选用sessionstorage/localstorage/cookie存储.

params:参数不会显示到路径上

1：配置路径router

export default new Router({
  routes: [
    {
      path: '/testVueRouter',
      name: 'TestVueRouter',
      component: TestVueRouter
    },
    {
      path: '/testVueRouterTo',
     // 一定要写name,params必须用name来识别路径
      name: 'TestVueRouterTo',
      component: TestVueRouterTo
    }
  ]
})

2：传递参数：用$router

<!-- test-vue-router页面 -->
<template>
  <div>
    <a @click="routerTo()">query传参</a>
  </div>
</template>
<script>
export default {
  methods: {
    routerTo() {
      this.$router.push({
        name: `TestVueRouterTo`,
        params: {
          page: '1', code: '8989'
        }
      })
    }
  }
}
</script>

3：接受参数：用$route，少个r,注意啦

<!-- test-vue-router-to页面 -->
<template>
  <div>
  </div>
</template>
<script>
export default{
  data() {
    return {
      page: '',
      code: ''
    }
  },
  created() {
    this.getRouterData()
  },
  methods: {
    getRouterData() {
      this.page = this.$route.params.page
      this.code = this.$route.params.code
      console.log('page', this.page)
      console.log('code', this.code)
    }

  }
}
</script>

query：最好也用name来识别，保持与params一致性，好记了，路径传参

1：路径配置（跟params一样，代码不写了）

2：传递参数页

<!-- test-vue-router页面 -->
<template>
  <div>
    <a @click="routerTo()">query传参</a>
  </div>
</template>
<script>
export default {
  methods: {
    routerTo() {
      this.$router.push({
        name: `TestVueRouterTo`,
　　　　　// 只是把query改了，其他都没变
        query: {
          page: '1', code: '8989'
        }
      })
    }
  }
}
</script>

3：接受参数

<!-- test-vue-router-to页面 -->
<template>
  <div>
  </div>
</template>
<script>
export default{
  data() {
    return {
      page: '',
      code: ''
    }
  },
  created() {
    this.getRouterData()
  },
  methods: {
    getRouterData() {
      // 只是改了query，其他都不变
      this.page = this.$route.query.page
      this.code = this.$route.query.code
      console.log('page', this.page)
      console.log('code', this.code)
    }

  }
}
</script>

图片区：

下面我们采用path: '/testVueRouterTo'

1：query（成功）

<!-- test-vue-router页面 -->
<template>
  <div>
    <a @click="routerTo()">query传参</a>
  </div>
</template>
<script>
export default {
  methods: {
    routerTo() {
      this.$router.push({
        path: '/testVueRouterTo',
        query: {
          page: '1', code: '8989'
        }
      })
    }
  }
}
</script>

<!-- test-vue-router-to页面 -->
<template>
  <div>
<!--     <span>{{page}}</span>
    <span v-show="code === '89'">{{code}}</span>
    <span>{{password}}</span> -->
  </div>
</template>
<script>
export default{
  data() {
    return {
      page: '',
      code: '',
      password: ''
    }
  },
  created() {
    this.getRouterData()
  },
  methods: {
    getRouterData() {
      // debugger
      this.page = this.$route.query.page
      this.code = this.$route.query.code
      console.log('page', this.page)
      console.log('code', this.code)
    }

  }
}
</script>

2：params:（不成功）

<!-- test-vue-router页面 -->
<template>
  <div>
    <a @click="routerTo()">params传参</a>
  </div>
</template>
<script>
export default {
  methods: {
    routerTo() {
      this.$router.push({
        path: '/testVueRouterTo',
        params: {
          page: '1', code: '8989'
        }
      })
    }
  }
}
</script>

<!-- test-vue-router-to页面 -->
<template>
  <div>
<!--     <span>{{page}}</span>
    <span v-show="code === '89'">{{code}}</span>
    <span>{{password}}</span> -->
  </div>
</template>
<script>
export default{
  data() {
    return {
      page: '',
      code: '',
      password: ''
    }
  },
  created() {
    this.getRouterData()
  },
  methods: {
    getRouterData() {
      // debugger
      this.page = this.$route.params.page
      this.code = this.$route.params.code
      console.log('page', this.page)
      console.log('code', this.code)
    }

  }
}
</script>

这是由于query与params传参机制不一样，造成的差异，如果要隐藏参数用params，如果强制刷新不被清除用query
