I'm updating a site and I'm questioning some of the javascript. I'm quite new to javascript, but I'm wondering how much of this might be for very old browsers, and how much is still required today. For example: I'm seeing usage like if (document.images) { which from googling seems like that's testing for IE3's lack of support. Do I need to worry about IE3 users today? I also see document.all instead of getElementByID. What percent of browsers don't support that DOM method? The page also is using ypSlideoutMenu from 2001. Anyone familiar with this? Would you consider it acceptable javascript? http://cvs.sourceforge.net/viewcvs.py/ypslideoutmenus/ypSlideOutMenus/ypSlideOutMenus.js?rev=1.2&view=auto http://ypslideoutmenus.sourceforge.net/demo/index.html -- Bill Moseley moseley at hank.org
