Allow me to elaborate.
I have created a form field module. Its a simple select box with a custom query to populate its options.
it is set to "unlimited" values in my content type, so i can "add new item" and order them.
This works perfect.

What im trying to do is add a onchange event to each select box so using jquery i can display details about the selected option (each option references some other node on the site).

Can someone point me in the right direction?
thanks

If I remember correctly, I added js in the head (or a .js file), that on load, set the onchange of the form element.
This allowed me to add the js w/o changing the form markup.

$(document).ready(
    function(){
       $('elementID').change(function(){
	   //do something
	});			
    });

I think you can also use the [#attributes] for the form element. $form['myelementid']['#attributes'] = array('onchange' => 'myJsFunction();');
which will put the onclick inline. <select id="myelementid" onchange="myJsFunction();"> ... </select>

I have created a cck field. In the node-form it is a select box, and i want to include a onchange event for the field. I tried to include using '#attributes" but it doesnt work out for me.

The code :
$form['field_first_level_category']['#attributes'] = array('onchange' => 'retrieveNextLevel();');
I am using '#attribute' to pass php values to js function.

Could any one please help me to get it done?

Sorry there is a question:

I want to add this attribute, but I don't know where!
would you please inform me exactly where can I add this $form['myelementid']['#attributes'] = array('onchange' => 'myJsFunction();');

You can define conditional field from cck and select the conditional filed from lest of field on add form.

I am needing to select checkboxes on event 'hover' or 'mousedown' so that a user can click and drag the mouse over checkboxes which will then be checked/unchecked.

Can anyone help me with this?
