In mobile devices' safari, <a href="#" onclick="return false"> doesn't work, why?

Question

In moblie devices' safari, like iphone or ipad, <a href="#" onclick="return false"> doesn't prevent default behaviour, the page was still redirected to '#', why...? Like these html code:

<div style="height:1000px; width:100px"></div>
<br />    
<a href="#" onclick="return false">click me</a>

When click in moblie devices' safari, it goes back to the top of the page...

I had the same problem. It turns out that it is a bug in the iOS 5 version of Safari. Doesn't happen in newer or older versions, or any other browser or platform.

I resolved it by adding preventDefault to the onclick event handler, in addition to the existing return false, like so:

<a href="#" onclick="event.preventDefault(); return false;">click me</a>

Not ideal, but it does solve the problem.
