代码运行效果
首先引入vue地址
<script src="https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"> </script>运用v-model 和key
<div id = "box">
<input type = "text" v-model="mytext"/>
<ul>
<li v-for ="data in test()" :key="data">
{
{data}}
</li>
</ul>
<!-- {
{ test() }} -->
</div>导入可见数据
data:{
mytext:"",
datalist:["aaa","add","bbb","bbc","ccc","ddd","eee","ade"]
},完整代码

<ul>

</ul>
<!-- {

</div>
<script>
var vm = new Vue({
el:"#box",
data:{
mytext:"",
datalist:["aaa","add","bbb","bbc","ccc","ddd","eee","ade"]
},
methods:{
test(){
return this.datalist.filter(item=>item.includes(this.mytext))
}
}
})
</script>
</body>
