ipad safari: disable scrolling, and bounce effect?

Solution 1:

This answer is no longer applicable, unless you are developing for a very old iOS device...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

Update September 2014: A more thorough approach can be found here: https://github.com/luster-io/prevent-overscroll. For that and a whole lot of useful webapp advice, see http://www.luster.io/blog/9-29-14-mobile-web-checklist.html

Solution 2:

You can also change the position of the body/html to fixed:

body,
html {
  position: fixed;
}
