我想從組件向父方法發送參數。但是我收到了這些錯誤消息“[Vue 警告]：v-on 處理程序中的錯誤：“TypeError：無法讀取未定義的屬性 'deleteClicked'”我想將參數從組件發送到 deleteClicked 函數。我的javascript代碼如下。var sablon = Vue.extend({    props: ["name"],    template: '<button type="button" class="btn btn-warning" v-on:click=this.$parent.deleteClicked(name) style = "margin: 3px;" > {{ name }}</button > '});var viewmodel = new Vue({    el: '#divimiz',    components: { 'sablonx': sablon },    data: {        names: ['Mary', 'John', 'Robert'],        newname: '',        test: "selam",    },    methods: {        addname: function () {            this.names.push(this.newname);            this.newname = '';        },        deleteClicked: function (item) {            var x = this.names.indexOf(item);            if (x > -1) {                this.names.splice(x, 1);            }        },    },});我的html代碼如下，<script src="https://unpkg.com/vue/dist/vue.js"></script><link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"    integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"><div id="divimiz" class="container">    <div class="row">    <sablonx v-for="name in names" v-bind:name="name"></sablonx>    <br>    <input class="form-control" type="text" v-model="newname" style="width: 400px; margin: 5px;">    <button class="btn btn-info" v-on:click="addname">Click to add name</button></div><script src="x.js"></script>
