vue根据路由隐藏侧边栏

项目要求某模块显示侧边栏，某模块隐藏侧边栏，所有模块统一引用了一个layout组件，所以在路由里设置一个自定义属性，在layout组件里监听路由，判断自定义属性值来隐藏侧边栏

// An highlighted block
{
    path: '/equipment',
    component: Layout,
    name: 'equipmentLayout',
    hidden: true,
    meta: {
      title: '机电设备',
      icon: '框架'
    },
    children: [{
        path: '/equipment/index',
        name: 'equipment',
        component: () => import('@/views/equipment/index'),
        meta: {
          title: '机电设备',
          icon: '首页',
          hiddenSiderbar: true//隐藏侧边栏
        },
      },

    ]
  }

// An highlighted block
mounted(){
    //隐藏侧边栏
    if(this.$route.meta.hiddenSiderbar){
      this.hiddenSiderbar = true;
    }else{
      this.hiddenSiderbar = false;
    }
  },
  watch:{
    $route(to,from){
      if(to.meta.hiddenSiderbar){
        this.hiddenSiderbar = true;
      }else{
        this.hiddenSiderbar = false;
      }
    }
  },
