#render_js_message(type, hash = {}) ⇒ Object

Helper to render the js_message response.

Pass in a type of message (:ok, :error, :redirect) and any other data you need. Default data attributes in the response are:

* html
* message
* to (used for redirects)

Examples:

# Send a successful response with some html
render_js_message :ok, :html => "<p>It worked!</p>"

# Send a redirect
render_js_message :redirect, :to => "http://www.google.com"

# Send an error response with a message
render_js_message :error, :message => "Something broke!"

Of course, if you don’t need other data sent back in the response this works as well:

render_js_message :ok
