Rails - Nov 2007 - image_tag is missing "class=" attribute--how can I replace javscript behavior?

(Apologies if a previous message was posted inadvertently. My finger
slipped on the enter key.)

While converting a static HTML prototype to Rails I changed a bunch of
alinks from this:
<a href="find.html"><img
src=''/images/findTab.jpg'' alt="Find"
class="rollover" /></a>

to the more Railsesque construction shown here:
<%= link_to(image_tag(''findTab.jpg'', :alt =>
''Find an item''), :action
=> ''Find'') %>

Sharp-eyed readers will note that the class="rollover" attribute,
which was provided by Javascript, is now gone. While image_tag has
an :alt option in the hash there is no :class option.

How can I restore the class="rollover" attribute if image_tag
doesn''t
support it, or at least get the rollover behavior back somehow?

Thank you.

Tom Campbell

link_to takes a third argument that is a hash of html options:

<%= link_to(image_tag(''findTab.jpg'', :alt =>
''Find an item''), {:action=> ''Find''},
:class => ''rollover'') %>

Oops, I just noticed that you are applying that class to the image not 
the link, but this will work:

<%= link_to(image_tag(''findTab.jpg'', :alt =>
''Find an item'', :class => ''rollover''),
:action=> ''Find'') %>

However, that adds the class to the anchor tag, not the image...

Actually, any option you pass to image_tag will be in the generated html tag
as an attribute:

<%= link_to(image_tag(''findTab.jpg'', :alt =>
''Find an item'', :class =>
''rollover''), :action=> ''Find'') %>

Right, hence my second post 10 seconds after my first post:
