function CompareFirstFieldDateGreaterThanSecondFieldDate(ctrlIDFirst, ctrlIDSecound, ctrlNameFirst,ctrlNameSecound)
{
    var fieldDateFirst = document.getElementById(ctrlIDFirst).value ;
    var fieldDateSecound = document.getElementById(ctrlIDSecound).value ;

    if((fieldDateFirst == "")&&(fieldDateSecound == ""))
    {
        return true;
    }
    else
    {
        if(fieldDateFirst == "")
        {
            alert("Please enter " +ctrlNameFirst);
            //document.getElementById(ctrlIDFirst).value = ""; -- Commented By Perumal on 23 July 2010
            document.getElementById(ctrlIDFirst).focus();
            return false;
        }
        else if(fieldDateSecound == "")
        {
            alert("Please enter " +ctrlNameSecound);
           // document.getElementById(ctrlIDSecound).value = ""; -- Commented By Perumal on 23 July 2010
            document.getElementById(ctrlIDSecound).focus();
            return false;
        }
        else
        {
            fieldDateFirst = fieldDateFirst.split("/");
            var Date1 = new Date();
            Date1.setFullYear(fieldDateFirst[2],fieldDateFirst[1]-1,fieldDateFirst[0]);

            fieldDateSecound = fieldDateSecound.split("/");
            var Date2 = new Date();
            Date2.setFullYear(fieldDateSecound[2],fieldDateSecound[1]-1,fieldDateSecound[0]);

            if (Date1 > Date2)
            {
              return true;
            }
            else
            {
              //alert(" Please Enter "+ ctrlNameFirst + " and " + ctrlNameSecound +".");
              alert(ctrlNameFirst + " should be greater than " + ctrlNameSecound + ".");
              // document.getElementById(ctrlIDFirst).value = ""; -- Commented By Perumal on 23 July 2010
              document.getElementById(ctrlIDFirst).focus();
              return false;
            }
        }
    }
}

这很好用

This works fine

Just使用Javascript的Date对象来定义日期，然后简单地使用日期对象比较。



Javascript日期对象：http://www.w3schools.com/js/js_obj_date.asp [ ^ ]



样本：

Just use the Date object of Javascript to define the dates and then simply use the date object comparison.

Javascript Date object: http://www.w3schools.com/js/js_obj_date.asp[^]

Sample:

var myDate=new Date();
myDate.setFullYear(2010,0,14);
var today = new Date();
if (myDate>today)
{
  alert("Today is before 14th January 2010");
}
else
{
  alert("Today is after 14th January 2010");
}
