About 9 or 10 years ago I used to visit a site which had a javascript forum. There were some clever guys on there who used to do some clever stuff with javascript. A few of them - one of them was called Charles as I recall - used to constantly preach the message that you should not build sites that rely on javascript - if you do you are preventing people with disabilities from using them - and you could get sued under some legislation or other. (He was evangelical about it and cited the case of the people who created the web site for the Sydney Olympics in 2000 getting sued because of that problem.)

As I tend to develop business applications I used to ignore these warnings - in that javascript is seriously handy if you want to provide a decent user interface in a web application.

When I started using .Net about 4 years ago (I stuck with classic ASP until I was prised away from my keyboard) - I thought to myself ... hmm _doPostBAck is used all over the place by .Net ... has all this 'don't use javascript for anything essential' malarkey died a death?

So, my question is ... every asp.Net site uses javascript ... right? I mean, if they don't, you only have two server controls that cause postbacks.

If someone turns javascript off in their browser - 99.9% of .net sites won't work. Is this true? If so ... it's safe to use javascript on a public facing site without some nutjob suing you?

(I think I tried ebay recently (apologies to them if it wasn't them)) with javascript disabled and a message came up saying you must enable javascript in your browser).
