ipad safari: disable scrolling, and bounce effect?

Question

I'm working on a browser based app, currently I'm developing and styling for the ipad safari browser.

I'm looking for two things on the ipad: How can I disable vertical scrolling for pages that don't require it? & how can I disable the elastic bounce effect?

This answer is no longer applicable, unless you are developing for a very old iOS device... Please see other solutions

2011 answer: For a web/html app running inside iOS Safari you want something like

document.ontouchmove = function(event){
    event.preventDefault();
}

For iOS 5 you may want to take the following into account: document.ontouchmove and scrolling on iOS 5
