Evaluate javascript in Ajax.Request

Rails
1

Hi there,

does anyone know if it is possible to generate remote_function calls in
a dynamic fashion similar to this:

<%= remote_function(:url => {:action => “setComponent”, :component =>
comp, :value => document.getElementById("…").value})%>

where I don’t want to evaulate the document.getElementById part but
rather want to pass this javascript code to the Ajax.Request object for
later evaluation.

The problem here is that the document.getElementById("…").value part
is passed to the resulting Ajax.Request object as a string:

new
Ajax.Request(’/epacs/setComponent?component=3&value=document.getElementById(…).value’,
{asynchronous:true, evalScripts:true})

and seems to be never evaluated but rather passed to the server as a
string.

How do I create this remote_function call so that the javascript is
evaluated at the very same time that the Ajax.Request is fired?

Thanks a lot!

You need to use the :with option (ie remote_function :url =>
{…}, :with => …)
