1、练习v-for v-model 实现数据的增加和删除
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--cdn镜像快速导入Vue包-->
<script src="https://cdn.bootcss.com/vue/2.6.11/vue.js"></script>
</head>
<body>
<div id="app">
<!---->
id:<input type="text" value="id" v-model="id">
姓名:<input type="text" value="name" v-model="name">
性别:<input type="text" value="sex" v-model="sex">
<input type="button" value="添加" @click="btnAdd">
<input type="button" value="删除" @click="btnDel">
<p v-for="(user,i) in users" :key="user.name">
<input type="checkbox" @click="getState(i)">
序号:{{user.id}},姓名:{{user.name}},性别{{user.sex}}</p>
</div>
<script>
//2.创建一个vue实例
var vm = new Vue({
el: '#app', //表示当前我们new的这个Vue实例，要控制页面上的哪个区域
data: { //data属性中存放的是el中要用到的数据
users:[
{id:1,name:"yang",sex:'男'},
{id:2,name:"jie",sex:'男'},
{id:3,name:"shao",sex:'女'}
],
id:'',
name:'',
sex:'',
index:0,
},
methods:{
btnAdd(){
this.users.push({id:this.id,name:this.name,sex:this.sex})
},
getState(i){
console.log(i)
this.index = i
},
btnDel(){
console.log(this.index)
this.users.splice(this.index,1)
}
}
})
</script>
</body>
