Hi list,

I'm trying to get a local javascript variable submitted with remote\_function:

\<script language="javascript"\>

var local\_variable = "I do really important stuff"; \<%= remote\_function :url =\> {:action =\> "boo", :id=\> 1}, :submit =\> 'local\_variable' %\>

\</script\>

The above snippet seems to be close but generates new Ajax.Updater('foo', '/temp/boo/1', {asynchronous:true, evalScripts:true, parameters:Form.serialize('local\_variable')})

but I don't want the form to be serialized (there is no form!) I want the value of 'local\_variable' to be serialized and submitted. Any ideas?

Thanks, Dan

Maybe remote\_function [http://rubyonrails.org/api/classes/ActionView/Helpers/PrototypeHelper.html#M000420](http://rubyonrails.org/api/classes/ActionView/Helpers/PrototypeHelper.html#M000420) with a :with parameter will help?

thanks - looks like this might do the trick:

remote\_function :url =\> {:action =\> "boo", :id=\> 1}, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:with =\> "'variable='+local\_variable"

It looks like this appends &variable=blah to the URL which is enough for me, but it would be interesting to see if it could serialise and post variable values as well - maybe some other time!
