However, you cannot therefore guarantee that the form element will always have the same ID. Usually I'd add a class to the item I want to add the behaviour to (in form alter or theme function), and then attach the javascript using the Drupal.behaviors technique.

Drupal will not create the elements with the same ID. So do in this way is OK.

I am adding some jQuery to my form to update a field value. It works but I think there should be a better way to select a field, I use "$('#...')" but I am worried it will not work if form is shown twice in a page. Any advice?

drupal_add_js("$(document).ready(function() {  $('#edit-data-assentament-popup-datepicker-popup-0').change(function () {    $('#edit-data-paper-popup-datepicker-popup-0').attr('value', $('#edit-data-assentament-popup-datepicker-popup-0').attr('value'));  });   $('#edit-data-paper-popup-datepicker-popup-0').blur(function () {     $('#edit-data-paper-popup-datepicker-popup-0').attr('value', $('#edit-data-assentament-popup-datepicker-popup-0').attr('value'));     $(this).unbind('blur');     $('#edit-data-assentament-popup-datepicker-popup-0').unbind('change');  }); });", 'inline');

thanks

I was hoping to find a way to tell my js code which id would have the form element. I inserted my js code inside the form() 2010/6/23 nan wich <nan_wich@bellsouth.net>:

Actually, if the same form is used more than once on a page, you can almost guarantee that it will *not* have the same name. Take a look at the comments in "form_clean_id()" concerning its effects on jQuery. I think adding a class might make this more difficult, unless that code is fully aware of multiple instances of a form on a page.
