Really nice tutorial, very concise and no rambling

Isn’t it alwasy good practice to santise you querystring data when using it directly in your script?

Thanks

Exactly, as soon as the User doesn’t have JavaScript enabled, your stuff won’t execute. This is also the reason, Jeffrey implements a non-JavaScript alternative most of the time as well.

Generally, you don’t have to worry about that issue, although it is never wrong to think of that special case and have a solution at hand from the beginning.

@Jeffrey:

Great tutorial, I finally got into more than the shallow jQuery stuff I already knew.

All the code you write in javascript will stop working if the users have the javascript ability disabled in their browser?

I’m assuming the browser have that ability enabled by default thus allowing to use javascript without worrying?

Great tutorials by the way, thanks.
