Is it good practice not to use much javascript/jquery? Should we avoid it as much as possible (for good accessibility)?
When is it OK to use JavaScript and when is it not in web design and development? In what scenarios and with what conditions?
Update:
I’m asking regarding public websites.
I have to respectfully disagree with the posters that say that you shouldn’t use JavaScript, or use it sparingly, or have it degrade gracefully.
The reason is that the vast majority of people nowadays has JavaScript enabled and appreciates the desktop-like experience it can provide from a website. Really, who doesn’t have JavaScript enabled? People act as if this is a statistically significant group. It is not.
Not using JavaScript is a little bit like nitpicking about variable sizes (oh, I can use a 16-bit integer here instead of 32-bit to save some memory). Unless you are doing some monster project for hundreds of thousands of people, where the ROI of the time you spend on making your website degrade gracefully is actually positive, you should use JavaScript as freely as you like. The two people that can’t access it because they disabled it are paranoid and probably not the kind of people you want as customers anyways.
Just my 2 cents.
