Question

I have a problem in my Rails Project. It runs on Rails 2 by the way.

<%= form.hidden_field :foo %>

Is it possible to get the value of this hidden field with jQuery?
Maybe something like this:

var foo = jQuery('hidden_field').val();

Any Ideas?

I would use the ‘:hidden’ selector in jQuery ( http://api.jquery.com/hidden-selector/ ). To expand on @Koraktor’s examples:

var foo = jQuery('#foo:hidden').val();

or

var foo = jQuery('form#some_form input[name="foo"]:hidden').val();
