jQuery and Browser Compatibility

jQuery is actively supported in all these browsers:

• Firefox 2.0+
• Internet Explorer 6+
• Safari 3+
• Opera 10.6+
• Chrome 8+

There are known problems with outdated browsers as per the list below:

• Mozilla Firefox 1.0.x
• Internet Explorer 1.0-5.x
• Safari 1.0-2.0.1
• Opera 1.0-9.x
• Konqueror

jQuery generally works with Konqueror and Firefox 1.0.x, but there may be some unexpected bugs since we do not test them as regularly.

If you are using any of the outdated browsers, then this could be your problem, otherwise, you should post your code here on stackoverflow to get help. It may not be the browser causing the problem, but it could be the way code is written or executed.

I think part of your problem is that you're accessing something from the file system that is meant to be loaded from a web server. For example, I see this error in Chome on your chapter 2 example:

XMLHttpRequest cannot load file://...chapter2/dom.sample.html.
Origin null is not allowed by Access-Control-Allow-Origin.

Things seem to be behaving reasonably well in Chrome other than that sort of thing.

I usually target IE[789], Chrome, Firefox, Safari, and Opera and I haven't seen many browser issues that are specific to jQuery or jQuery-UI. The problems are mostly CSS issues and certain JavaScript problems (in IE for both) that aren't jQuery problems.

Version 3 of jQuery is maintained for the following desktop browsers :

• Chrome: (Current - 1) and Current
• Edge: (Current - 1) and Current
• Firefox: (Current - 1) and Current
• Internet Explorer: 9+
• Safari: (Current - 1) and Current

It is also maintained for the following mobile browsers :

• Stock browser on Android 4.0+
