Is there any way to make an Ajax call (like link_to_remote) and pass in
the value of a field on screen? This seems obvious, but I can’t find
anything…
Thanks,
Marcus

You could not use the helper and do this:
Where url is the url of your controller/action and pars are the params
you wanna pass.
or write your own helper that does this. Didn’t see a way to do it with
the existing one.

ah… would be nice if the api docs had that as part of link_to_remote
options.
Found it under observe_field
:with
“A JavaScript expression specifying the parameters for the
XMLHttpRequest. This defaults to â??valueâ??, which in the evaluated context
refers to the new field value. If you specify a string without a “=”,
itâ??ll be extended to mean the form key that the value should be assigned
to. So :with => “term” gives “â??termâ??=value”. If a “=” is present, no
extension will happen.”
Thanks! will try that.

If you need more help let me know.
