[mordy]

I thought i would share my fixes

$j(document).ready(function(){
(function($) {
$(function() {
if(!('placeholder' in document.createElement("input"))) { //don't do any work if we don't have to!
var inputs = $('input[type="text"][placeholder]');
var origColour = inputs.eq(0).css("color");

            inputs
                .each(function(i) {
                    var $t = $(this);
                    if($t.val()===''){
                        $t.val($t.attr("placeholder")).css("color", "#585858");
                    }
                })
                .focus(function() {
                    var $t = $(this);
                    if( $t.val() === $t.attr("placeholder")) $t.val('').css("color", origColour);
                })
                .blur(function() {
                    var $t = $(this);
                    if($t.val() === '') {
                        $t.val($t.attr("placeholder")).css("color", "#585858");
                    }
                });
            var $password_fields = $('input[type="password"][placeholder]');
            origColour = $password_fields.eq(0).css("color");

            $password_fields
                .each(function(i) {
                    var $t = $(this);

                    $copy = $('<input type="text">')
                        .val($t.attr("placeholder"))
                        .css("color", "#585858")
                        .hide()
                        .focus(function(){
                            $copy.hide();
                            $t.show().focus();
                        });
                    $t.after($copy);
                    $t.data('placeholder',$copy);
                    if($t.val()===''){
                        $t.hide();
                        $copy.show();
                    }
                })
                .blur(function() {
                    var $t = $(this);
                    if($t.val() === '') {
                        $copy = $t.data('placeholder');
                        $copy.show();
                        $t.hide();
                    }
                });
        }
    })

})(jQuery);
