将form表單序列化成json對象

serializeObject = function (form) {
    var o = {};
    $.each(form.serializeArray(), function (index) {
        if (o[this['name']]) {
            o[this['name']] = o[this['name']] + "," + this['value'];
        } else {
            o[this['name']] = this['value'];
        }
    });
    return o;
};
