vue-router 根据name属性判断是否拥有该路由, 留个存根, 也分享给大家

	  hasRoute(name, routeList) {
        !routeList && (routeList = this.$router.options.routes, console.log('执行'))
        for (let i = 0; i < routeList.length; i++) {
          console.log(routeList[i])
          if (routeList[i].name === name) {
            return true
          }
          if (routeList[i].children) {
            let flag = this.hasRoute(name, routeList[i].children)
            if(flag){
              return flag
            }
          }
        }
        return false
      }

调用

	  jump(name) {
	    // 因为返回的是true或者false  所以直接判断了
        if(!this.hasRoute(name)){
          this.$message("无权限查看页面");
        }else{
          this.$router.push({name:name})
        }
      }
