关于checkbox对应一张表时如何遍历

html代码：

 <table>
     <tr>
         <td><input name='one' type='checkbox' value='1'/></td>
         <td name="name">张三</td>
         <td name="age">35</td>
         <td name="job">职员</td>
         <td naem="sal">3444</td>
     </tr>
     <tr>
         <td><input name='one' type='checkbox' value='1'/></td>
         <td name="name">李四</td>
         <td name="age">34</td>
         <td name="job">职员</td>
         <td naem="sal">4555</td>
     </tr>
     <tr>
         <td><input name='one' type='checkbox' value='1'/></td>
         <td name="name">王二</td>
         <td name="age">55</td>
         <td name="job">boss</td>
         <td naem="sal">10000</td>
     </tr>
 </table>
 <button id="btn" value="submit">submit</button>

js代码：

 <script src="jquery-2.1.4/jquery.min.js"></script>

 <script>
     $(document).ready(function () {
         $("#btn").click(function () {
             var row;
             $("input[type='checkbox']").each(function () {
                 if($(this).is(":checked")){
                //获取整个表，为下面遍历
                     row = $(this).parent("td").parent("tr");
               //比较val(),html(),text()的区别
                     var  str = row.html();
                     var str1 = row.val();
                     var str2 = row.text();
                     alert(str);
                     alert(str1);
                     alert(str2);
              //采用find() childen()方法进行选择
                     var str3 = row.find("td").text();
                     var str4 = row.find("td").val();
                     var str5 = row.find("td").html();
                     alert(str3);
                     alert(str4);
                     alert(str5);
                     var str6 = row.find(".name").text();
                     var str7 = row.find(".name").val();
                     var str8 = row.find(".name").html();
                     alert(str6);
                     alert(str7);
                     alert(str8);
                 }

             })
         })
     })
 </script>
