I want to make a call to remote_function with 1 of the parameters
derived from a javascript call.
For example:
<%= remote_function(:url => {:action = "xyz", :id =>
getId()}, :update
=> ''main_content'') %>
getId() is a Javascript function.
Can something like this be done?
Conversely,
can the remote_function(options) call be made from javascript.
Something like
def f()
{
var options = {"url": {"action": "xyz",
"id" : getId()}, "update":
"main_content"};
remote_function(options);
}

The javascript clearly cannot be evaluated at the time that the <%= is evaluated, since that happens server side. However, the remote_function family do take a :with option, which is a string of javascript to be executed and bashed into the parameters when the ajax call is made. I wrote up some of the ways of playing with the :with option at http://www.spacevatican.org/2008/5/17/with-or-without-you-link_to_remote-s-mysterious-parameter> > Conversely, > can the remote_function(options) call be made from javascript. >remote_function just generates some javascript, usually something like new Ajax.Updater(''some_div'', /foo/bar, {some: options} Fred> Something like > def f() > { > var options = {"url": {"action": "xyz", "id" : getId()}, "update": > "main_content"}; > remote_function(options); > } > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
