By - # default this is the current form, but - # it could just as well be the ID of a - # table row or any other DOM element. - # <tt>:with</tt>:: A JavaScript expression specifying - # the parameters for the XMLHttpRequest. - # Any expressions should return a valid - # URL query string. - # - # Example: - # - # :with => "'name=' + $('name').value" - # - # You can generate a link that uses AJAX in the general case, while - # degrading gracefully to plain link behavior in the absence of - # JavaScript by setting <tt>html_options[:href]</tt> to an alternate URL. - # Note the extra curly braces around the <tt>options</tt> hash separate - # it as the second parameter from <tt>html_options</tt>, the third. - # - # Example: - # link_to_remote "Delete this post", - # { :update => "posts", :url => { :action => "destroy", :id => post.id } }, - # :href => url_for(:action => "destroy", :id => post.id) - def link_to_remote(name, options = {}, html_options = nil) - link_to_function(name, remote_function(options), html_options || options.delete(:html)) - end - # Creates a button with an onclick event which calls a remote action # via XMLHttpRequest # The options for specifying the target with :url |
