[support] Adding attributes to forms (exposed filters) in a page view

Hi I have been banging my head on this problem for quite some time now and really cant get anywhere close I want to add some error checking code to the exposed filters in the page view. For this I want to access the DOM of the output of the views_build_view call . So that I can add javascript events to the elements of the forms etc . How can I do this ??? In terms of drupal I think this will boil down to something like accessing the form array (Form API) of the form the exposed filters in a view create (My guess - adding an attribute here can help get a onclick event on the submit button of the form for example). Any pointers would be really helpful. Regards Abhinav
