HEllo Team,

I am in trouble . As The Code is very Simple.

C#

var regExpDEOID = /^[0-9]*$/;
           if ($('#topCountForQCTextbox').val() == '' || !regExpDEOID.test($('#topCountForQCTextbox').val())) {
               alert("Please enter proper values in allocation count");
               return false;
           }

I have the textbox namely topCountForQCTextbox
My validation is for if the textbox is empty and not equal to regExpDEOID.

But when i am inserting the value in textbox as 1 , it gives me message "Please enter proper values in allocation count" which is wrong as per my Regular Expression.

Please Guide me where I am getting wrong.
Thanks Harshal.

It depends on the context of this code. Also, are you sure you have id="topCountForQCTextbox" for this control?

Please try is as below.

C#

var regExpDEOID = /^[0-9]*$/;
var topText=$('#topCountForQCTextbox').val();

if ($.trim(topText).length == 0 || !regExpDEOID.test($('#topCountForQCTextbox').val())) {

   alert("Please enter proper values in allocation count");
   return false;
}
