Uppercase First Letter in Form

You can also easily do this with some jQuery. In this case, simply apply the custom class "capitalize" (via the form admin) to any field you want capitalized. Then, add the following to your page template.

<script type="text/javascript">
jQuery.noConflict();
  jQuery(document).ready(function($) {

		$('li.capitalize input').keyup(function(event) {
		    var textBox = event.target;
		    var start = textBox.selectionStart;
		    var end = textBox.selectionEnd;
		    textBox.value = textBox.value.charAt(0).toUpperCase() + textBox.value.slice(1);
		    textBox.setSelectionRange(start, end);
		});

  });
</script>

I grabbed the snippet from here and it works well in my tests.
