HTML5 placeholder disappears on focus

Question

Is there a freely available jQuery plugin that changes placeholder behavior to match HTML5 spec?

Before Focus

Answer 1

How about something simple like this? On focus save out the placeholder attribute value and remove the attribute entirely; on blur, put the attribute back:

$('input[type="text"]').focus( function(){
  $(this).attr("data-placeholder",$(this).attr('placeholder')).removeAttr("placeholder");
});
$('input[type="text"]').blur( function(){
  $(this).attr("placeholder",$(this).attr('data-placeholder'));
});
