Vue实现动态添加或者删除对象和对象数组的操作方法
(编辑：jimmy 日期: 2025/9/23 浏览：2)
添加核心代码如下：
this.data.push({
type: [{
value: '选项1',
label: 'in'
},
{
value: '选项3',
label: 'out'
}],
value:[{
value: '选项1',
label: 'CSV'
},
{
value: '选项3',
label: 'TSV'
}],
parameter:'',
default:'',
description:'',
isDelete:false,
});
删除核心代码如下：
/*遍历数组，然后根据选中的状态获取对应的下标，然后进行删除*/
for (let i = 0;i<this.data.length;i++){
let obj = this.data[i];
if (obj.isDelete){
this.data.splice(i,1);
i--
}
}
全部代码如下：
<template>
<div>
