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

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

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);
}
