Platform Testing
JavaScript for Plone core must be tested on:
- IE 7, 8, 9
- Firefox, current release and most-recent beta or rc for the next release, if available
- Webkit browsers: Current
In general, degrade gracefully to no-js behavior when a platform cannot be supported. You need not support IE 6, but if you know that a feature works poorly on IE 6, simply turn it off:
if (jQuery.browser.msie && parseInt(jQuery.browser.version, 10) < 7) {
return;
}
