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--      }     }
