     *     <input type="text" name="lname" value="lee"/>
     *     <input type="text" name="fname" value="zq"/>
     * </form>
     *
     * $('#form').serialize() 返回：lname=lee&fnaem=zq
     * 
     * $('#form').serializeArray() 返回：[{name: lname, value: lee}]
     *
     * 以下方法转成：
     * $('#form').serializeObject() 返回：{lname: lee}，更方便 json 格式提交
