解决vue 子组件修改父组件传来的props值报错问题

 <input v-model="currentSearch" type="text" class="input-search" @keydown.enter="doSearch">

export default {
  name:"round-search-bar",
  props:['search'],  //父组件传来的值
  data(){
    return {
      currentSearch: this.search  //通过data, 定义新变量currentSearch, 这样currentSearch的值变更时，不会影响父组件传来的search的值
    }
  },
  methods: {
    doSearch(){
      Util.searchAPI(this.$router,this.currentSearch)
    }
  },
}
