javascript - Showing Placeholder text for password field in IE

I know there is a ton of placeholder questions, but I am trying to perfect mine.

My current code works great and does what it's supposed to. The problem is, when I go to place the "password" placeholder, it puts the placeholder in the masking characters. Any ideas on how to get around that?

    $(function() {
if(!$.support.placeholder) { 
        var active = document.activeElement;
    $(':text').focus(function () {
        if ($(this).attr('placeholder') != '' && $(this).val() ==  $(this).attr('placeholder')) {
            $(this).val('').removeClass('hasPlaceholder');
        }
    }).blur(function () {
        if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
            $(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
        }
    });
    $(':text').blur();
    $(active).focus();
    $('form').submit(function () {
        $(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
    });

    var active = document.activeElement;
    $(':password').focus(function () {
        if ($(this).attr('placeholder') != '' && $(this).val() == $(this).attr('placeholder')) {
            $(this).val('').removeClass('hasPlaceholder');
        }
    }).blur(function () {
        if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
            $(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
        }
    });
    $(':password').blur();
    $(active).focus();
    $('form').submit(function () {
        $(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
    });
}
   });

My field for the pass:

  <div id="loginform_pass"><input class="login" tabindex="2" type="password" placeholder="Password" name="password" maxlength="30"></div>

You could also try this... it detects that the browser does not have support for placeholder and works for all input types

function FauxPlaceholder() {
        if(!ElementSupportAttribute('input','placeholder')) {
            $("input[placeholder]").each(function() {
                var $input = $(this);
                $input.after('<input id="'+$input.attr('id')+'-faux" style="display:none;" type="text" value="' + $input.attr('placeholder') + '" />');
                var $faux = $('#'+$input.attr('id')+'-faux');

                $faux.show().attr('class', $input.attr('class')).attr('style', $input.attr('style'));
                $input.hide();

                $faux.focus(function() {
                    $faux.hide();
                    $input.show().focus();
                });

                $input.blur(function() {
                    if($input.val() === '') {
                        $input.hide();
                        $faux.show();
                    }
                });
            });
        }
    }
    function ElementSupportAttribute(elm, attr) {
        var test = document.createElement(elm);
        return attr in test;
    }
