Disabling iOS elastic body scroll & keep native scrolling working

Question

I am currently working on a single page web app optimized for touch devices, mainly iOS. I've implemented the new iOS native scrolling via -webkit-overflow-scrolling: touch; and all works well except that we are still experiencing the apple elastic scroll effect on the whole page body.

This involves the whole page moving off the top/bottom of the viewport when a scroll ends or the body is pushed and really gives away the fact that this is a web app. I have followed various guidelines on how to prevent this and while they do work, they prevent inner scrollable elements from working altogether.

Here's a fiddle to demonstrate what I'm using so far.

Has anyone found a solution that disables body elastic scrolling but lets inner scrollables work?

Solution 1

I've adapted the good solution from Conditionally block scrolling/touchmove event in mobile safari using Dojo:

var initialY = null;
dojo.connect(document, 'ontouchstart', function(e) {
    initialY = e.pageY;
});
dojo.connect(document, 'ontouchend', function(e) {
    initialY = null;
});
dojo.connect(document, 'ontouchcancel', function(e) {
    initialY = null;
});
dojo.connect(document, 'ontouchmove', function(e) {
    if(initialY !== null) {
        if(!dojo.query(e.target).closest('#content')[0]) {
            // The element to be scrolled is not the content node
            e.preventDefault();
            return;
        }

        var direction   = e.pageY - initialY;
        var contentNode = dojo.byId('content');

        if(direction > 0 && contentNode.scrollTop <= 0) {
            // The user is scrolling up, and the element is already scrolled to top
            e.preventDefault();
        } else if(direction < 0 && contentNode.scrollTop >= contentNode.scrollHeight - contentNode.clientHeight) {
            // The user is scrolling down, and the element is already scrolled to bottom
            e.preventDefault();
        }
    }
});

The element to be scrolled is #content in this case.

Maybe iScroll is what you're looking for (if I got your question right)
