Rails - Nov 2006 - degradable ajax links

hey all

I know you can use form_remote_tag to help create degradable form tags
but what about links?  Seems it may be doable, not sure actually, with
some combination of a regular anchor element and a remote_function call
but I would be surprised if there wasn''t a more idiometric aproach?

Am I missing something obvious!

Thanks in advance!
Tim

uhm i think link_remote_to degardes gracefully by default.

it would create something like this:

<a href="/bla/blubb" onClick="AJAX Code Goes
Here">Blablabla</a>

The onclick event does the ajax call and stops the default behaviour
(requesting the page pointed at by href=""). If Javascript is
disabled,
the normal href="" target is requested as the behaviour is not stopped
by JavaScript....

could be wrong though, didnt do much ajax yet and not at my machine at
the moment. ....

link_to_remote doesn''t: it sets the href to "#"

You should check out the Unobstructive Javascript (UJS) plugin 
(http://www.ujs4rails.com/) it has helpers that do this kind of thing 
properly (and more). The guys behind it also gave a nice presentation 
about it at railsconf europe, you can grab the slides from their 
presentation off the same website

Not by default, but it can be told to. The method signature is:

      def link_to_remote(name, options = {}, html_options = {})

If you include :href => <degraded URL> in the html_options argument, it
will be used. If not, the tag''s href will be set to #.
