vue不推荐直接在子组件中修改父组件传来的props的值,会报错

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "result" (found in component )


 <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)
 }
 },
}
