javascript - 使用 jquery 动态获取一些 tr 值并使用 ajax 将它们传递给 php

Question

我想在按下“删除”按钮时将一些 td 值传递给 ajax 调用我如何使用 jquery 做到这一点？

<table>
       <tr>
          <td class="datao">first column</td>
          <td class="data1">first column</td>
          <td class="data2">first column</td>
          <td colspan="2"></td>
       </tr>
       <tr>
          <td class="datao">xzczxc</td>
          <td class="data1">xzczxc</td>
          <td class="data2">xzczxc</td>
          <td>   
             <input type="button" class="deleteRow" value="Delete" />
          </td>
       </tr>
       <tr>
          <td class="datao">xzczxc</td>
          <td class="data1">xzczxc</td>
          <td class="data2">xzczxc</td>
          <td>   
             <input type="button" class="deleteRow" value="Delete" />
          </td>
       </tr>
       <tr>
          <td class="datao">xzczxc</td>
          <td class="data1">xzczxc</td>
          <td class="data2">xzczxc</td>
          <td>   
             <input type="button" class="deleteRow" value="Delete" />
          </td>
       </tr>
       <tr>
          <td class="datao">xzczxc</td>
          <td class="data1">xzczxc</td>
          <td class="data2">xzczxc</td>
          <td>   
             <input type="button" class="deleteRow" value="Delete" />
          </td>
       </tr>
       <tr>
          <td class="datao">xzczxc</td>
          <td class="data1">xzczxc</td>
          <td class="data2">xzczxc</td>
          <td>   
             <input type="button" class="deleteRow" value="Delete" />
          </td>
       </tr>
</table>

更新:假设我想获取 's 中 input type=text 的值。

HTML 示例:

 <table>
           <tr>
              <td class="datao">
                 <select class="someclass">
                    <option value="asdsa">somevalue</option>
                 </select>
              </td>
              <td class="datao">
                 <input type="text" value="eqw" />
              </td>
              <td class="datao">
                 <input type="text" value="gfg" />
              </td>
              <td>   
                 <input type="button" class="deleteRow" value="Delete" />
              </td>
           </tr>
           <tr>
              <td class="datao">
                 <select class="someclass">
                    <option value="wq">somevalue</option>
                 </select>
              </td>
              <td class="datao">
                 <input type="text" value="hfd" />
              </td>
              <td class="datao">
                 <input type="text" value="vcv" />
              </td>
              <td>   
                 <input type="button" class="deleteRow" value="Delete" />
              </td>
           </tr>
           <tr>
              <td class="datao">
                 <select class="someclass">
                    <option value="cva">somevalue</option>
                 </select>
              </td>
              <td class="datao">
                 <input type="text" value="ewd" />
              </td>
              <td class="datao">
                 <input type="text" value="asad" />
              </td>
              <td>   
                 <input type="button" class="deleteRow" value="Delete" />
              </td>
           </tr>
 </table>

jquery的代码:

假设我想获取每行数据的 select 值...

$('input.deleteRow').live('click', function() {
        var values = [];

        $(this).closest('tr').find("select").each(function() {
            values.push($(this).attr('value'));
        });

        //Confirm 
        //the ok stores true or false returned by confirm!
        var ok = confirm("Are you sure...?");

        //testing for true
        if(ok){
            $.post("phpscript.php", { someName:values[0] }, function(data) {
                if(data == '1'){
                    alert("something");
                    location.reload();              
                }
                else
                    alert("something else, error probably");
            });
        }

    });

如果你想获取 select 和 input type="text"只需要做:...find("select, input[type=text]")...

这是我对社区的贡献。无论如何，我想找到一种将数据发送到 php 脚本的优雅方式，请帮帮忙。
