uni-app之数组的操作

1、往数组添加一条数据：array.unshift({});

this.LRecordList.unshift({
  'FID': LRecordID,
  'FLeaveStuUserID': currentUserID,
  'FUserName': currentUserName,
  'FLeaveClassID': this.currentClassID,
  'FLeaveType': currentLType_1,
  'FStartTime': currentStartDate + " 00:00:00",
  'FEndTime': currentEndDate + " 00:00:00",
  'FLeaveNote': currentLExplain,
  'FSubTime': currentDate_2,
  'FApprovalStatus': 1
});

2、删除数组的某一条数据：array.splice(获取到的下标值,1);

this.LRecordList.splice(clickLRecordIndexNum, 1); //删除

3、修改数组的某一条数据
先删除，后添加

//删除
this.LRecordList.splice(clickLRecordIndexNum, 1); 
//添加
this.LRecordList.unshift({
  'FID': LRecordID,
  'FLeaveStuUserID': currentUserID,
  'FUserName': currentUserName,
  'FLeaveClassID': this.currentClassID,
  'FLeaveType': currentLType_1,
  'FStartTime': currentStartDate + " 00:00:00",
  'FEndTime': currentEndDate + " 00:00:00",
  'FLeaveNote': currentLExplain,
  'FSubTime': currentDate_2,
  'FApprovalStatus': 1
});
