Does IE9 RTW support the placeholder attribute on input elements?

Question

A bunch of sites mention support in IE9, but I assume this was something that appeared in the Betas, or RC. It doesn't appear to be supported in IE9 final. Can someone confirm this?

Answer 1

No, placeholder text for form elements was never implemented for IE9. It is easily (and commonly) done with JavaScript.

Placeholder support was added in IE10.
