jquery获取完整的html方法，兼容ie8,firefox

(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() {
            if (this.checked) this.setAttribute('checked', 'checked');
            else this.removeAttribute('checked');
        });
        $("option", this).each(function() {
            if (this.selected) this.setAttribute('selected', 'selected');
            else this.removeAttribute('selected');
        });
        return oldHTML.apply(this);
    };
})(jQuery);

调用方法：$("#abc").formhtml();
