In creating and testing our Joomla! extensions are came across certain Javascript compatibility issues. After a great deal of research we were able to develop some scripts that fixed some annoying problems.

One of the bigger problems was with the latest IE9 (Internet Explorer 9) browser where we were getting a script5022: dom exception invalid_character_err (5). This error is triggered by most of the earlier framework versions. So if you have Javascript written using an older version framework your website may not work as expected on the newest IE browser. We have developed a small script that you can place in your web pages that will fix this problem without the need for an expensive upgrade. Take a look it may be well worth the price. script5022
