Simple Placeholder Fallback that is dependent on Modernizer. I am sure there is a cleaner way, but I just wanted to see if I could do it from scratch.

Placeholder-Fallback

  if(!Modernizr.input.placeholder) {
		$('[placeholder]').each(function(i){ $(this).val($(this).prop('placeholder')); });
		$('[placeholder]').on({
			'focus' : function(evt){
				if($(this).val() === $(this).prop('placeholder')) { $(this).val(''); }
			},
			'blur' : function(evt){
				if($(this).val() !== $(this).prop('placeholder')) { $(this).val($(this).prop('placeholder')); }
			}
		});
		$('.block-internal-form').submit(function(){
			$('[placeholder]').each(function(i){
				if($(this).val() === $(this).prop('placeholder')) { $(this).val(''); }
			});
		});
	}
