修改input的text 通过jquery的html获取值 未变化
扩展一个方法 ，通过formhtml()来取代html()

(function ($) {
    var oldHTML = $.fn.html;
    $.fn.formhtml = function () {
        if (arguments.length) return oldHTML.apply(this, arguments);
        $("input,textarea,button", this).each(function () {
            this.setAttribute('value', this.value);
        });
        $(":radio,:checkbox", this).each(function () {
            // im not really even sure you need to do this for "checked"
            // but what the heck, better safe than sorry
            if (this.checked) this.setAttribute('checked', 'checked');
            else this.removeAttribute('checked');
        });
        $("option", this).each(function () {
            // also not sure, but, better safe...
            if (this.selected) this.setAttribute('selected', 'selected');
            else this.removeAttribute('selected');
        });
        return oldHTML.apply(this);
    };

    //optional to override real .html() if you want
    // $.fn.html = $.fn.formhtml;
})(jQuery);
