代码如下所示：
<div id="app"> <input v-model="inputValue"> <button @click="handleSumbit">提交</button> <todo-item v-for="(item,index) of list":key="index":content="item":index="index" @delete="handleDelete"></todo-item> </div>
子组件向父组件传递数据使用 this.$emit('delete',this.index)该方法
<script >
Vue.component('todo-item',{
props:["content",'index'],
template:"<li @click='handleSubmit'>{{content}}{{index}}</li>",
methods:{
handleSubmit:function () {
this.$emit('delete',this.index)
}
}
})
new Vue({
el:'#app',
data:{
inputValue:'',
list:[]
},
methods:{
handleSumbit:function () {
this.list.push(this.inputValue);
this.inputValue="";
},
handleDelete:function (index) {
this.list.splice(index,1)
}
}
})
</script>
