解决vue 子组件修改父组件传来的props值报错问题

时间:2020-05-17 254980080 人气:0

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)
    }
  },
}
