Need to remove a character from a form upon submission.

Hi, we have a gift certificate form. magickitchen.com/gift/gift-certificates.html - cart is written in PERL,

In the amount window, if someone enters a dollar sign before the number, they get an error. Error: Invalid input for VALUE: $|$35|

Is there a simple way to remove the $ sign if someone enters it, as the form is submitted? Or is there another simple solution?

As an interim measure, I'll be changing the placeholder text. Thanks.

To remove a $ character from any string...

$str =~ s/\$//go;

Open in new window

Thanks... I'll need a little more explanation, I think. I know that's jquery, but I'm not sure how or where to add it to make that work. Thanks, David.

Not sure why it isn't working here though: http://dev.magickitchen.com/gift/gift-certificates.html scroll down to the form.

I have this in the head tag:

     <script language="javascript" type="text/javascript" src="/js/cart/jquery-1.7.1.min.js"></script>
 <script>
 $(".allownumericwithdecimal").on("keypress keyup blur",function (event) {
            //this.value = this.value.replace(/[^0-9\.]/g,'');
     $(this).val($(this).val().replace(/[^0-9\.]/g,''));
            if ((event.which != 46 || $(this).val().indexOf('.') != -1) && (event.which < 48 || event.which > 57)) {
                event.preventDefault();
            }
        });
	</script>

Open in new window

And the input field has: <input class="form-control allownumericwithdecimal" name="gift_value" id="gift_value" type="text" placeholder="Amount (10 - 2500)*- enter without dollar sign">

Thanks gentlemen, the cart developer made changes to fix it, but this would have worked as well. Appreciated!
