### 18.合并params和query参数（Header组件+TypeNav组件） ###

目前代码的传参场景是：Header组件的搜索按钮按照params传参，而TypeNav组件的三级联动菜单采用query传参，合并参数的意义在于，无论是搜索按钮还是三级菜单联动都应该既包含query参数也包含params参数。

> 当下错误效果图如下，三级菜单跳转搜索后三级菜单的query参数没了，而搜索之后再跳转菜单时搜索的parms参数没了：

修改代码如下：

`Header组件`中

goSearch() {
         let location = {name: 'search', params:{keyword:this.keyword}};
          if (this.$route.query) {
            location.query = this.$route.query
          }
          this.$router.push(location)
        }

`TypeNav组件中`

//判断：如果路由跳转的时候，带有params参数，捎带脚传递过去
    if (this.$route.params) {
        location.params = this.$route.params;
    }

> 正确的效果图如下：
