remote_function(options) public

Returns the JavaScript needed for a remote function. See the link_to_remote documentation at http://github.com/rails/prototype_legacy_helper as it takes the same arguments.

Example:

  # Generates: <select id="options" onchange="new Ajax.Updater('options',
  # '/testing/update_options', {asynchronous:true, evalScripts:true})">
  <select id="options" onchange="<%= remote_function(:update => "options",
      :url => { :action => :update_options }) %>">
    <option value="0">Hello</option>
    <option value="1">World</option>
  </select>

Example

This function can be used to pass the ID of selected item, for example:

# with select or collection_select helpers:
{ :onchange => remote_function(:url => { :action => 'do_smth' }, :with => "'id=' + $('the_id').value") }

# and grab ID in controller action as usually: 
YourModel.find(params[:id])
