jQuery and rails' RJS templates

jQuery and rails' RJS templates

I'm not sure if I'm going about this the right way but here goes - I am using both jQuery and the rails default libraries (prototype and scriptaculous) in my app, and trying to send jQuery to the browser inside an RJS template or a render(:update) block. It typically looks something like this:
page.visual_effect :highlight 'some_div'
page << "jQuery('some_div').css('color', 'red');"

But it doesn't seem to work there. If I put the jQuery inside a js file in the header than all is great, but I also need some stuff in the page code.

I also tried to wrap it inside the document ready call
page << "jQuery( function () { jQuery('some_div').css('color', 'red'); });"

But not much happened there either.

Could this be done or am I just wasting my time?
