Comments on: Where is getElementsByClassName()? http://nexus.zteo.com/2007/01/14/where-is-getelementsbyclassname/ Variously Interesting Projects Thu, 18 Feb 2010 15:12:08 -0600 http://wordpress.org/?v=2.8.5 hourly 1 By: SneakyWho_am_i http://nexus.zteo.com/2007/01/14/where-is-getelementsbyclassname/comment-page-1/#comment-18177 SneakyWho_am_i Sun, 16 Nov 2008 12:57:21 +0000 http://nexus.zteo.com/2007/01/14/where-is-getelementsbyclassname/#comment-18177 Fortunately a lot of other people have written equivalent functions for the browsers yet to support this (IE6, IE7, IE8...) and old versions of proper browsers (Firefox, Opera, Safari). I say it's fortunate because Firefox (for example) can do it in XPath, which is something like a gazillion times faster than doing it your way :P - no offense intended there. Of course the main thing is to have this lifesaving function working, and a few picoseconds here and there probably don't matter at all. I know that premature optimizations are bad, and the faster you make this the bigger it gets. Still, worth googling at the moment to see how others have approached it! If you haven't played with XPath yet I recommend trying it out - it is a lot of fun :) Fortunately a lot of other people have written equivalent functions for the browsers yet to support this (IE6, IE7, IE8…) and old versions of proper browsers (Firefox, Opera, Safari).

Thanks for the information. I guess we can only hope for Microsoft to follow suit now. I shall absolutely test for it, then. Thanks for the information.

It's part of the Web Apps 1.0 Spec. http://www.whatwg.org/specs/web-apps/current-work/ Unfortunately the only browser that currently supports it is Firefox Beta 3. Nevertheless, it should be tested for in your script for future compatibility. Actually getElementsByClassName() does exist!
