When is it appropriate to use javascript?
Despite the obvious utility of many javascript functions for most users, I’ve given up using them as I cannot get anything to ever validate.
This isn’t ideal, as it creates antagonism on the client’s part towards 508 requirements.
Something I am currently struggling with I guess.
JavaScript can be used anywhere, anytime. The important thing is that it’s used unobtrusively and for enhancing the user experience. It should never be used for required functionality. I’d recommend researching ‘unobtrusive JavaScript’ and ‘progressive enhancement’. Jeremy Keith and Chris Heilmann are great resources.
