bug 552 - no double-click event on the iPad

Issue: #552
Affects: Safari on the iPad

Ok, calling this a bug is a big stretch because it was intentionally removed. This is more of a footnote that the dblclick event is not available in Safari on the iPad.

The reason is that the iPad reserves the double "tap" event to zoom in and out of a Web page.

However there's a few additional events that Safari on the iPad doesn't support (with no obvious reason) but we'll tackle in another post. ;-)

Example:

<script type="text/javascript">
  <div ondblclick="alert('this will never fire');">DBL Click Me</div>
</script>

bug 511 - checkbox double click fail in IE

Issue: #511
Affects: IE6, IE7, IE8, IE9, IE10

On the web almost all interaction is based on the single-click concept. You click once to follow a link, you click once to press a button, once to open a dropdown select list, select a radio button or checkbox element etc.

So if you were to double click an element that toggles (e.g. like a checkbox) you would expect the first click to change it from state A to state B... and the second to change it from state B back to state A. (e.g. unchecked - checked - unchecked)

This works as expected in all browsers except IE. In IE double-clicking a checkbox will only switch the state once from A to B.

Example:

Try Double Clicking these options:

Apple
Linux
Microsoft
HP
Dell
Cisco


Realistically this isn't a major issue as most users are unlikely to double click a checkbox... however based on the number of post on web forums and newsgroups about how to stop users from double clicking and re-submitting data - it certainly does happen.

Known Workarounds: None.
