This jQuery plugin removes the click delay from iOS webviews. Normally iOS defers the click event until 300ms has elapsed, to allow the user to trigger a zoom event with a double-tap. On views that don't support zooming, this causes a much longer delay than is necessary.
This is a drop-in solution: the code dispatches native click events to the elements in question, allowing onclick handlers to work 'as expected'.
Just include the script and decorate your no-click-delay elements with a "button" class. That's it:
<script src="jquery.noclickdelay.js"></script>
<a onclick="blah()" href="javascript:;" class="button">Click me!</a>
The script disables the default webkit highlight on elements that are tapped, as this highlight suffers from the 300ms delay. Instead, the script adds a "pressed" class to elements that the user taps. You can use this to offer your own active state UI.
