<input type="text" v-model="searchContent" style="border:1px solid red" @input="inputFun2">
<div v-for="(item,index) in optionsData" @click="getOptionInfo(item.value,item.text)" v-show="isshow" style="line-height:30px;cursor: pointer;">
       {{item.text}}
</div>

new Vue({
    el:"#demo4",
    data(){
          return{
              isshow:false,
              searchContent:"",
              optionsData:[],
              options2:[
