• vue-router路由如何实现传参


    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,可以参考我的另一边文章:sessionstorage、localstorage与cookie

    params:参数不会显示到路径上

    1:配置路径rutes

    复制代码
    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
        }
      ]
    })
    复制代码

    2:传递参数:用$router

    复制代码
    <!-- 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>
    复制代码

    3:接受参数:用$route,少个r,注意啦

    复制代码
    <!-- 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>
    复制代码

    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

    复制代码
    <!-- 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>
    复制代码

    3:接受参数

    复制代码
    <!-- 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>
    复制代码

    图片区:

    下面我们采用path: '/testVueRouterTo'

    1:query(成功)

    复制代码
    <!-- test-vue-router页面 -->
    <template>
      <div>
        <a @click="routerTo()">query传参</a>
      </div>
    </template>
    <script>
    export default {
      methods: {
        routerTo() {
          this.$router.push({
            path: '/testVueRouterTo',
            query: {
              page: '1', code: '8989'
            }
          })
        }
      }
    }
    </script>
    复制代码
    复制代码
    <!-- test-vue-router-to页面 -->
    <template>
      <div>
    <!--     <span>{{page}}</span>
        <span v-show="code === '89'">{{code}}</span>
        <span>{{password}}</span> -->
      </div>
    </template>
    <script>
    export default{
      data() {
        return {
          page: '',
          code: '',
          password: ''
        }
      },
      created() {
        this.getRouterData()
      },
      methods: {
        getRouterData() {
          // debugger
          this.page = this.$route.query.page
          this.code = this.$route.query.code
          console.log('page', this.page)
          console.log('code', this.code)
        }
    
      }
    }
    </script>
    复制代码

    2:params:(不成功)

    复制代码
    <!-- test-vue-router页面 -->
    <template>
      <div>
        <a @click="routerTo()">params传参</a>
      </div>
    </template>
    <script>
    export default {
      methods: {
        routerTo() {
          this.$router.push({
            path: '/testVueRouterTo',
            params: {
              page: '1', code: '8989'
            }
          })
        }
      }
    }
    </script>
    复制代码
    复制代码
    <!-- test-vue-router-to页面 -->
    <template>
      <div>
    <!--     <span>{{page}}</span>
        <span v-show="code === '89'">{{code}}</span>
        <span>{{password}}</span> -->
      </div>
    </template>
    <script>
    export default{
      data() {
        return {
          page: '',
          code: '',
          password: ''
        }
      },
      created() {
        this.getRouterData()
      },
      methods: {
        getRouterData() {
          // debugger
          this.page = this.$route.params.page
          this.code = this.$route.params.code
          console.log('page', this.page)
          console.log('code', this.code)
        }
    
      }
    }
    </script>
    复制代码

    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
