如何在日期选择器中获取特定的未来日期

Question

I have some data comprising startdate and enddate.

When I edit that data, I want to only allow future dates in enddate datepicker, but that has to be one day greater than the startdate.

For Example: If startdate = 01/05/2020, then I want enddate to be 01/06/2020 or greater than that in datepicker.

I tried that with a function naming getNextDayToStartDate() but I know I am doing something wrong.

Thanks.

Answer 1

  onEditData(data): void {
    var newdate = this.getNextDayToStartDate(data.startDate);
    this.editData = {
      Name: data.Name,
      startDate: this.getDate(data.startDate),
      endDate: newdate
    }
    this.editDataDialog = true;
  }

Your function to add a day returns a value, yet you continue with the original value. Capturing the returnvalue and using that, solves the issue.

Small sidenote: momentjs is a rather usefull thing for working with dates :) Might want to look in to that ;)

将 editData.startDate 添加到您的 html 中的方法调用中，这将修复它！

<input type="date" [min]="getNextDayToStartDate(editData.startDate)" [(ngModel)]="editData.endDate">
