vue如何实现清空this.$route.query的值

//如果有当前localStorage isTest 则 清空query
 if(localStorage.getItem('isTest')){
     this.$router.push({ query: {} })
 }
//
 if(this.$route && this.$route.query && this.$route.query.id){
     //定义一个 localStorage isTest
     localStorage.setItem('isTest', true)
     // 这里处理携带进来的参数
 }

destroyed() {
   localStorage.removeItem('isTest')
}

npm i WEBpack-merge

import merge from 'webpack-merge';

this.$router.push({
    query:merge(this.$route.query,{'id':'630'})
})
