javascript DateTime函数和验证 [英] javascript DateTime function and validations

问题描述

您好我有3个文本框： -

1）StartDate

2）EndDate

3）MyDate

所有3个都有从日历中获取的日期值。



我想验证它们，以便MyDate应该在使用Javascript的开始日期和结束日期之间。

如果无效，那么我想显示一条消息。

怎么做？

我认为我们应该使用自定义验证控件要做到这一点，但如何实现呢？

任何指针都会有所帮助。

Hi I have 3 textboxs :-
1) StartDate
2) EndDate
3) MyDate
all the 3 of them has Date Values picked up from a Calender.

I want to validate them so that MyDate should be between the Start Date and End Date using Javascript.
If invalid, then I want to display a message.
How to do that?
I think we should be using custom validation controls to do that but how to implement that??
Any pointers will be helpful.

推荐答案

我想验证它们MyDate应该使用Javascript在开始日期和结束日期之间。

有多种方法可以做到这一点。最简单的是在onclick或page submit等任何事件上引发JS方法，在这里您可以找到三个控件，获取三个日期并进行比较。



示例：

I want to validate them so that MyDate should be between the Start Date and End Date using Javascript.
There can be various ways to do it. Simplest is to raise a JS method on any event like onclick or page submit, where you find the three controls, get the three dates and compare.

Sample:

function checkDateValues(startDateValue, endDateValue, myDateValue)
{
  var sDate = new Date(startDateValue);
  var eDate = new Date(endDateValue);
  var mDate = new Date(myDateValue);
  if(mDate > sDate && mDate < eDate)
  {
     // All good
     return true;
  }
  return false;
}
