Fixing JavaScript/Prototype problems in IE 8: A matter of class(Name)

Posted 8 months, 2 weeks ago at 09:55. 2 comments

While testing our pages in Internet Explorer 8, we found quite a lot of JavaScript errors. It turned out that, among other differences, Internet Explorer 8 doesn’t support getAttribute(‘className’) on DOM nodes as IE 7 did before, but requires the (correct) getAttribute(‘class’). The old way will now just create a ‘className’ attribute which does nothing.

This surfaced indirectly through the use of the (old) version 1.6.0.3 of Prototype in Magento. Upgrading to version 1.6.1 fixed most JavaScript issues with Internet Explorer 8.

    The problems should be fixed if you replace the original prototype.js with the newer 1.6.1 release. That version is the first to support IE 8. I’ve done this and not encountered any backwards compatibility issue.
    Good luck!
