I tried a few simple jQuery manipulation on <button>
tags but, for some reasons, didn't work on IE7.
<!-- HTML -->
<button class="button">Hello</button>
// jQuery, using v1.4.4
$('button').html('Hello World!'); // Works on Firefox and IE7.
$('button').addClass('another-class'); // Works on Firefox; *not* on IE7.
$('button').wrapInner('<span></span>'); // Works on Firefox; *not* on IE7.
Does anyone have any clues about this?
