javascript to add commas while typing

[peac3]

Hi guys,

I have a textbox in .net and need to be able to add commas while typing dynamically and I've tried to search online but haven't got luck, here's what I found and not working

<script type="text/javascript">
    $(document).ready(function () {
        $('[id$="jquicomma"]').keyup(function () {
            if (this.value.length % 4 == 3) this.value = this.value + ",";
        });
      });
</script>

<asp:TextBox ID="jquicomma" runat="server" Width="90%"></asp:TextBox>

anyone could help will be appreciated, Thanks!

not tested this but you could try something like this (note that this does not take into account whether the character is an alphanumeric or something else like a carriage return);

$(document).ready(function () {
        $('#jquicomma').keyup(function ( e ) {
			var numChars = 3; //separate every three characters
			var numCommas = $(this).text().split(',') - 1;
            if (  ($(this).text().length - numCommas) % 3 == 0){
				$(this).text( $(this).text() + ',');	
			}
        });
      });
