How to add an attribute to a CCK node reference field?

By iansears on 5 Nov 2008 at 19:50 UTC

I use CCK and made a node reference field that I use in a Form.
I need to ADD an attribute to the input object when it renders in a web page.
How is this done?

Here is my example:

<label for="edit-field-org-node-reference-0-node-name">Organization: </label>
 <input type="text" maxlength="128" name="field_org_node_reference[0][node_name]" id="edit-field-org-node-reference-0-node-name"  size="60" value="" class="form-text form-autocomplete" />

needs to become the same input field but an added "attribute" that runs a javascript function onchange... like this:

<label for="edit-field-org-node-reference-0-node-name">Organization: </label>
 <input type="text" maxlength="128" name="field_org_node_reference[0][node_name]" id="edit-field-org-node-reference-0-node-name"  size="60" value="" class="form-text form-autocomplete" onChange="lookupinfo(this.value)" />

See that last attribute?

I tried following this but got stuck: http://drupal.org/node/117346
and this: http://api.drupal.org/api/file/developer/topics/forms_api_reference.html...

My attribute works great outside of Drupal in straiht html calling an embedded javascript, but I am having difficulty in how to add this attribute javascript call INTO my existing CCK custom node reference field. Any ideas anyone?

Thanks in advance for thinking about this. :-)

#attributes overwritten

I have been working on a similar problem. I have found something that might help you. See http://drupal.org/node/161666#comment-272621.

I think you could put something like in your hook_form_alter():

drupal_add_js("
     $(document).ready(function () {
        $('#edit-field-org-node-reference-0-node-name').change(function () {
           lookupinfo(this.value);
        });
     });", "inline");

I want my javascript applied to several elements so I want to add a class to the relevent elements that will be found by jquery. Unfortunately it appears that CCK is overwriting my #attributes property.
