如果不使用组件的话可不可以实现这个功能？自己尝试了一下发现不知道如何获取当前点击的<li>标签的索引。

<body>
<div id='root'>
<input v-model='inputValue'/>
<button @click='handleAdd'>添加</button>
<ul>
<li v-for="(item, index) in list" :key='index' :index="index" @click='handleDelete(index)'>{{item}}下标{{index}}</ul>
</ul>
</div>
</body>
<script>
new Vue({
el: '#root',
data: {
inputValue:'',
list:[]
},
methods: {
handleAdd: function() {
this.list.push(this.inputValue)
this.inputValue=''
},
handleDelete: function(e) {
this.list.splice(e.target,1)
}
}
})
</script>
</html>
