JQuery1.72中二个Bug,formhtml()方法与clone()方法的二个Bug进行重写

//扩展方法$.formhtml,解决firefox中html()方法得不到修改input值后的html代码
(function ($) {
    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);

//重写clone方法/textarea和select的值clone的时候会丢掉,具体查看http://asialee.iteye.com/blog/1753447
(function (original) {
    jQuery.fn.clone = function () {
        var result = original.apply(this, arguments),
            my_textareas = this.find('textarea').add(this.filter('textarea')),
            result_textareas = result.find('textarea').add(result.filter('textarea')),
            my_selects = this.find('select').add(this.filter('select')),
            result_selects = result.find('select').add(result.filter('select'));
        for (var i = 0, l = my_textareas.length; i < l; ++i) $(result_textareas[i]).val($(my_textareas[i]).val());
        for (var i = 0, l = my_selects.length; i < l; ++i) result_selects[i].selectedIndex = my_selects[i].selectedIndex;
        return result;
    };
})(jQuery.fn.clone);
