我的理解，組件中methods是個對象，而不是一個函數(shù)，畢竟method帶有s哦

應(yīng)該用雙引號 @click="HandClick"index? ?而且上面漏了單引號? props:['content','index']

methods:{
handleSumbit:function(){
this.list.push(this.inputValue);
this.inputValue = '';
},
handleDelete:function(index){
this.list.splice(index,1);
}
}

不是這個問題

你的method方法，掉了參數(shù)index，應(yīng)該為
handleDelete:function(index){ ? ? ? ? ? ?
this.list.splice(index,1)? ? ? ??
}
