How does page.update actually work? I know its a wrapper for
Prototype.update but how does it get the partial in there?
Say I wanted to update a div with the contents of a partial manually
like this.
content = render(:partial => ''whatever'')
page.call "$(''my_div'').update(#{content})"
But his does not work. It keeps giving me weird errors about
tags. Any clues?

The first argument is supposed to be the function to call (ie $(''my_div'').update) and subsequent arguments are arguments to pass through. What your code does is ask the browser to execute $(''my_div'').update(<span>some html here</span>) (assuming that was the html content), ie the string literal is not quoted and is just dumped in there. There is no need to use page.call here though as page.replace_html handles this already (see http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper/JavaScriptGenerator/GeneratorMethods.html#M001446 ) Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I am aware of page.update and page.replace_html but I was wondering how it actually works. Basically I have a callback from a scriptaculous effect that will update a div with the results of some partial so I can not use the built in page.xxx calls. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Anyway, first off you can use update_page to get an rjs like page object anywhere you happen to be. Secondly prototype''s update stuff is as simple as $(''some_div'').update(''hello world''). If however you are generating the html in rails and then just injecting it into some javascript with #{} then you need to quote the string of html properly (and if you quote the string with " you need to escape any " in the html (and similarly with ''). page.call does all that for you, there''s a helper whose name I forget that does that and to_json would probably do the trick too.
