下面将介绍两种方式实现动态添加和删除列表
1.不使用组件
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue 测试实例 - vue实现列表增加和删除</title>
<script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
<input v-model="newAddText" placeholder="请输入要添加的内容" />
<button @click='addNewList'>添加</button>
<ul>
<li v-for='(list,index) in lists' v-bind:key='list.id'>
{{list.title}} <button v-on:click='lists.splice(index, 1)'>删除</button>
</li>
</ul>
</div>
<script>
var vm = new Vue({
el: '#app',
data: {
newAddText:'',
lists:[
{id:1,title:'手机号码'},
{id:2,title:'qq号'},
{id:3,title:'姓名'},
],
nextTodoId: 4
},
methods:{
addNewList:function(){
this.lists.push({
id:this.nextTodoId++,
title:this.newAddText
})
this.newAddText=''
}
}
})
</script>
</body>
</html>
初始界面：
添加一个列表：
删除一个列表：
2.使用组件方法
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue 测试实例 - vue实现列表增加和删除</title>
<script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
<input v-model="newAddText" placeholder="请输入要添加的内容" />
<button @click='addNewList'>添加</button>
<ul>
<li is='list-item' v-for='(list,index) in lists' v-bind:key='list.id'
v-bind:title='list.title' v-on:remove='lists.splice(index,1)'>
</li>
</ul>
</div>
<script>
Vue.component('list-item', {
template: '\
<li>\
{{ title }}\
<button v-on:click="$emit(\'remove\')">删除</button>\
</li>\
',
props: ['title']
})
var vm = new Vue({
el: '#app',
data: {
newAddText:'',
lists:[
{id:1,title:'手机号码'},
{id:2,title:'qq号'},
{id:3,title:'姓名'},
],
nextTodoId: 4
},
methods:{
addNewList:function(){
this.lists.push({
id:this.nextTodoId++,
title:this.newAddText
})
this.newAddText=''
}
}
})
</script>
</body>
</html>
效果跟上面的一样的！
