I just punched in www.verizon.com and found that I could not do a service check with my phone number, because their site is using the document.all property, which has been deprecated for quite some time in favor of the document.getElementById(‘id’); property in JavaScript.
I’m quite surprised at this…I’m using a Mac with Firefox 2.0 and came across the problem.
The solution for me was check AT&T and Charter Cable for comparable services…perhaps they will get on board with the W3C sooner rather than later, and write unobtrusive javascript, instead of requiring it.
