用的iview框架,触发Input的自动获取焦点的功能:

但是动态生成的input组件只能获取一次焦点

上代码

html
<div v-for="(info,index) in pageInfo.data" :key="info.fid">
    <span  v-if="currentIndex_file !== index"  @click="getcurFile(index)" >{{info.positionName}}</span>
    <Input  v-show="currentFile === index" @on-blur="directModify(info.fid,index)" :ref="'file'+index"></Input>
</div>

js

//data值
data() {
    return {
        this.currentIndex_file = null;
        this.currentFile = null;
    }
},
//methods方法
methods:{
    getcurFile(index){
      this.currentIndex_file = index;
      //将当前的赋值给currentIndex
      this.currentFile = index;
      //写在$nextTick,动态获取ref
      this.$nextTick(()=>{
        this.$refs['file'+index][0].focus()
      })
    }
}

完美解决~
