在atable的每个tr中选中的三个复选框中，只有一个可以使用jQuery选中

我有一个复选框表，我希望每行三个复选框中只有一个被选中。我写了一个代码，它适用于每一行，但当我选中第二行中的复选框时，第一行复选框将被取消选中

            <td class="col_featured-ad"><input type="checkbox" id="featured3_ad2" class="radio2 price featured3" value="featured3_ad2" name="featured_ad2" />
            </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured7_ad2" class="radio2 price featured7" value="featured7_ad2" name="featured_ad2" />
              </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured15_ad2" class="radio2 price featured15" value="featured15_ad2" name="featured_ad2" />
              </td>
          </tr>

您可以在上查看代码

            <td class="col_featured-ad"><input type="checkbox" id="featured3_ad2" class="radio2 price featured3" value="featured3_ad2" name="featured_ad2" />
            </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured7_ad2" class="radio2 price featured7" value="featured7_ad2" name="featured_ad2" />
              </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured15_ad2" class="radio2 price featured15" value="featured15_ad2" name="featured_ad2" />
              </td>
          </tr>

这是HTML

            <td class="col_featured-ad"><input type="checkbox" id="featured3_ad2" class="radio2 price featured3" value="featured3_ad2" name="featured_ad2" />
            </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured7_ad2" class="radio2 price featured7" value="featured7_ad2" name="featured_ad2" />
              </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured15_ad2" class="radio2 price featured15" value="featured15_ad2" name="featured_ad2" />
              </td>
          </tr>

            <td class="col_featured-ad"><input type="checkbox" id="featured3_ad2" class="radio2 price featured3" value="featured3_ad2" name="featured_ad2" />
            </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured7_ad2" class="radio2 price featured7" value="featured7_ad2" name="featured_ad2" />
              </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured15_ad2" class="radio2 price featured15" value="featured15_ad2" name="featured_ad2" />
              </td>
          </tr>

有什么建议吗？提前谢谢大家。

我的建议是，您没有正确使用复选框。应使用复选框选择多个元素。如果您只希望选择一个元素，则应使用专门为此情况设计的单选按钮。然后，除了使用复选框代替单选按钮之外，您不需要使用任何JavaScript。

            <td class="col_featured-ad"><input type="checkbox" id="featured3_ad2" class="radio2 price featured3" value="featured3_ad2" name="featured_ad2" />
            </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured7_ad2" class="radio2 price featured7" value="featured7_ad2" name="featured_ad2" />
              </td>
            <td class="col_featured-ad"><input type="checkbox" id="featured15_ad2" class="radio2 price featured15" value="featured15_ad2" name="featured_ad2" />
              </td>
          </tr>

$('input.radio2:checkbox').click(function(){
    var $chk = $(this), $group = $chk.closest('tr').find('input.radio2:checkbox');
    if(this.checked){
        $group.not(this).prop('checked', false);
    }
});

演示：

是的，你说得对，我早就想到了。但那不是我的决定。我必须和你一起工作that@user2693896哈-好的，如果你真的需要使用这个，Arun P Johny的解决方案很好，但我认为你最好指导设计这个概念的人单选按钮是如何工作的。+1为开发者提供了一个解决方案，当开发者真的应该对不懂单选按钮的人大喊大叫。非常感谢你的回答。我的工作也做得很好你可以在这里查看
