Answer 1

ok,we take the the jquery.placeholder.js

and we can see the line 57

        // IE < 9 doesn't allow changing the type of password inputs
        if ($.browser.msie && input[0].outerHTML) {
            var fakeHTML = $(input[0].outerHTML.replace(/type=(['"])?password\1/gi, 'type=$1text$1'));
            this.fakePassword = fakeHTML.val(input.attr('placeholder')).addClass('placeholder').focus(function() {
                input.trigger('focus');
                $(this).hide();
                input.show();    //add this code
            });
            $(input[0].form).submit(function() {
                fakeHTML.remove();
                input.show()
            });
        }

add the code “input.show();” ,you can make the input not hide in IE8.
