[jQuery] Re: Better way to trim whitespace from input?

Well, you could try using a text transform CSS attribute on the text field.
Then you wouldn't have to perform a toUpperCase using JavaScript. But other
than that, looks about as lean as you can get it.

Subject: [jQuery] Better way to trim whitespace from input?


Hi,

I need to transform all characters entered in an input field to uppercase
and trim trailing whitespace.  This script works, but I'm wondering if
there's a better way to do it.

     <script>
         $(document).ready(function(){
                $("input").keyup(function (e) {
                $("#couponCode").val($(this).val().toUpperCase());
              });
           $("button").click(function () {
                        var couponCode = $("#couponCode").val();
                        couponCode = jQuery.trim(couponCode);
             });
           });
        </script>


Any suggestions?

Thanks in advance.
