Vue实现动态添加或者删除对象和对象数组的操作方法

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,
     });

/*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--
      }
     }
