Brian Glass pointed out the excellent JQuery hint plugin, which also solves the issue I wrote about recently (having text in an input field automatically disappear when you click on it).
The comment was lost because I was messing with my Disqus settings (careful, there!), but I thought it was worth pointing to; a small thing, but quite handy.
In the long run, it’s an incredible time savings not to have to re-solve these sorts of small problems every time you create a form.
Actually, that comment was made by Brian Glass.
:-( Doh. Editing that now.
Another problem with losing comments… oooops. Thanks, Brian!
