Menu
iOS 5 now allows native overflow: scroll support.
What I'd like to do is disable the touchmove event for everything except elements that have the 'scrollable' class or their children.
But I can't seem to get it to work; this is what I've been working with below:
<html>
<head>
<style>
.scrollable {
height: 5em;
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
// doesn't seem to work
var handleMove = function (e) {
if (!$(e.target).parents().andSelf().hasClass('scrollable')) {
e.preventDefault();
}
};
document.addEventListener('touchmove', handleMove, true);
</script>
</head>
<body>
<div>
don't scroll if you drag here
</div>
<div class='scrollable'>
should be scrollable if you drag here
<ul>
<li>and here</li>
<li>and here</li>
<li>and here</li>
<li>and here</li>
<li>and here</li>
<li>and here</li>
<li>and here</li>
<li>and here</li>
</ul>
</div>
don't scroll if you drag here
</body>
</html>

I know it's been a while since you asked the question, but I had the same issue and I used your code as the basis for solving the problem. So thanks for the inspiration.
(Javascript + jQuery)
<script>
var handleMove = function (e) {
var scrollable = false;
var items = $(e.target).parents();
$(items).each(function(i,o) {
if($(o).hasClass("scrollable")) {
scrollable = true;
}
});
if(!scrollable)
e.preventDefault();
};
document.addEventListener('touchmove', handleMove, true);
</script>
Or less verbose, but ultimately the same result (credit J Griffiths):
<script>
var handleMove = function (e) {
if($(e.target).closest('.scrollable').length == 0) { e.preventDefault(); }
}
document.addEventListener('touchmove', handleMove, true);
</script>
You should also include the following META tag.
<meta name="viewport" content="width=device-width, initial-scale=1.0,
maximum-scale=1.0, user-scalable=no;" />
