Vue实现动态添加或者删除对象和对象数组的操作方法

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:[{val

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：
