I have to validate that in a date field, date only is entered WITHOUT TIME.
Is there a quick way to this.
Thanks,
Rajkumar

Hello Yordangs,
I appreciate your help. It works OK.
Could you please also guide me on how to have the default date appear in DD/MM/YY format?

Rajkumar

the code seems a bit complex to me but that may be because everything in it is in spanish.
You could instead of using the regular expression use the split() method for strings.
var date = "6/10/1978".split("/"
var day = date[0];
var month = date[1];
var year = date[2];
// then here you would do the rest of the check.
To answer your question ramrakhyani there is a way to get the two digit value of the year.
For example :
var today = new Date(); // when there are not arguments it takes current date
var myStringDate = today.getDate() + "/" + (today.getMonth+1) + "/" today.getYear();
However if you wanted the four digit year :
var myStringDate = today.getDate() + "/" + (today.getMonth+1) + "/" today.getFullYear();
The difference is in the getFullYear() or getYear() methods that are part of the Date object that comes with JavaScript.
I hope this helps. Gary Haran

Hello Yordangs,
Further to my e-mail dated 23 April 2002, I found out an error in the Date validation function.
If once the date is validated as false, then valida(strDate)continues to return false even after the date has been corrected.
Could you please help on this.
Thanks,
Raj
