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);
