使用方法:arr.splice(arr.indexOf(ele),length):表示先获取这个数组中这个元素的下标,然后从这个下标开始计算,删除长度为length的元素
这种删除方式适用于任何js数组
eg:
<template>
<div class="users">
<button type="button" class="btn btn-danger" v-on:click="deleteUser(user)"><span class="glyphicon glyphicon-trash" aria-hidden="true"></span>删除</button>
</div>
</template>
<script>
//引入jquery
export default {
data(){
return {
users:[
{
name:'zx',
age:18,
addrress:'江苏南京',
email:'[email protected]',
contacted:false,
},
{
name:'zhiyi',
age:19,
addrress:'中国北京',
email:'[email protected]',
contacted:false,
},
{
name:'zhuxu',
age:20,
addrress:'中国上海',
email:'[email protected]',
contacted:false,
},
]
}
},
methods:{
deleteUser:function(user){
//表示先获取这个元素的下标,然后从这个下标开始计算,删除长度为1的元素
this.users.splice(this.users.indexOf(user),1);
}
}
};
</script>
