CustomValidator not calling javascript

Question

I am trying customvalidator control of asp.net but the problem is that it is not calling the javascript function. However it is calling the server side version of the validation method..

          <asp:CustomValidator  EnableClientScript="true"  
                ID="RegularExpressionValidatorFixedNames" runat="server"  ControlToValidate="TextBoxChapterName" 
                Text="Name not allowed" Font-Size="XX-Small"
                ValidationGroup="Name" 
                ClientValidationFunction="LQA_Validate"
                onservervalidate="RegularExpressionValidatorFixedNames_ServerValidate">   </asp:CustomValidator>

the javascript function

         function LQA_Validate(sender, args) {
        var re = /(?! My Ls|My As|My Qs).*/ig;
        args.IsValid = re.test(args);
    }

the server side method

          protected void RegularExpressionValidatorFixedNames_ServerValidate(object source, ServerValidateEventArgs args)
{
    Regex regex = new Regex(@"^(?!My Ls|My Qs|My As).*", RegexOptions.IgnoreCase);
    args.IsValid = regex.IsMatch(args.Value);
}

what can be the problem is this problem because of the regex or I am doing some technical mistake?

I used console.log but the javascript function is called at all.. — Spirals Whirls, May 24 '13 at 16:07
what it (console) gives any error like _function undefined_? — Dhaval Marthak, May 24 '13 at 16:08
What is the `args` variable? The `.text()` method expects a string, but if its a string primitive you can't assign an `.IsValid` property to it. — nnnnnn, May 24 '13 at 16:09
The two regexes are _not_ the same. One is matching a pattern against the start of the string (using `^`) and the other is not. — nnnnnn, May 24 '13 at 16:11
@nnnnnn I tried that ^ in javascript but was not working either. — Spirals Whirls, May 24 '13 at 16:13
The JS expression also has an extra space at the beginning. Either way we have no way to tell you whether the regexes are "correct" because we don't know what they're supposed to do. Again, what is the `args` variable? Use `console.log(sender)` and `console.log(args)` inside your JS function. — nnnnnn, May 24 '13 at 16:15

The problem is this:

 function LQA_Validate(sender, args) {
    var re = /(?! My Ls|My As|My Qs).*/ig;
    args.IsValid = re.test(args);
}

In re.test(args) you should use re.test(args.Value);

So the code must be:

 function LQA_Validate(sender, args) {
    var re = /(?! My Ls|My As|My Qs).*/ig;
    args.IsValid = re.test(args.Value);
}
