Friday, January 9th, 2009>p>Thomas Fuchs has created defaultValueActsAsHint, an implementation of the Input Prompt pattern:
An often occuring UI pattern is “use the value of a textfield as hint what to input”. These fields all auto-clear when the user first focuses it (by clicking or tabbing it), and if nothing it entered, the hint will be shown once again once the user leaves it.
This is all there’s to it, and the file to include is merely 18 lines of code. It works with textareas, too. Just specify whatever should be displayed as hint in the value attribute of the input (or as text within the textarea tag) and off you go. Define a ‘hint’ style if you like to show the text in gray, italics or whatever you fancy.
