Event Actions on an edit form

[RGClay]

First, I'm a newbie to nuBuilder and a novice at PHP and mysql. That said, I was wondering how I could display the running length of a textarea on an edit form after each character is entered into the field (presumably using the keydown event or an event that makes sense.)? Any direction would be appreciated.

RGClay,
no PHP or MySQL, but jQuery:

• add an html object to your form to display remaining characters in textarea;
• in Javascript tab insert this code:

  Code: Select all

  function nuLoadEdit() {
    $('#my_textarea_id').keyup(function () {
      var max = 10;
      var col = 'grey';
      var len = $(this).val().length;
      if (len >= max) {var col = 'red';}
      $('#html-obj')
        .text(max - len)
        .css('color', col);
    });
  }

Hope this helps,
Max

Thanks for the prompt reply. I'll be trying this first thing in the morning. I've found nuBuilder software to be exceptional! Many thanks to all involved!
