jQuery的单选按钮列表依赖

Question

在我调查的网页我有一组相同的物品radiobuttonlists的都具有相同的类：

  <asp:RadioButtonList ID = "rbFirstList" runat = "server" CssClass= "tbiDiagnosis"> 
       <asp:ListItem Text = "0. No" Value = "0"></asp:ListItem> 
       <asp:ListItem Text = "1. Yes, one episode" Value = "1"></asp:ListItem> 
       <asp:ListItem Text = "2. Yes, two episodes" Value = "2"></asp:ListItem> 
       <asp:ListItem Text = "3. Yes, three episodes" Value = "3"></asp:ListItem> 
       <asp:ListItem Text = "4. Yes, four episodes" Value = "4"></asp:ListItem> 
       <asp:ListItem Text = "5. Yes, five or more episodes" Value = "5"></asp:ListItem> 
       <asp:ListItem Text = "6. Uncertain" Value = "6"></asp:ListItem> 

      </asp:RadioButtonList> 

      <asp:RadioButtonList ID = "rbSecondList" runat = "server" CssClass= "tbiDiagnosis"> 
       <asp:ListItem Text = "0. No" Value = "0"></asp:ListItem> 
       <asp:ListItem Text = "1. Yes, one episode" Value = "1"></asp:ListItem> 
       <asp:ListItem Text = "2. Yes, two episodes" Value = "2"></asp:ListItem> 
       <asp:ListItem Text = "3. Yes, three episodes" Value = "3"></asp:ListItem> 
       <asp:ListItem Text = "4. Yes, four episodes" Value = "4"></asp:ListItem> 
       <asp:ListItem Text = "5. Yes, five or more episodes" Value = "5"></asp:ListItem> 
       <asp:ListItem Text = "6. Uncertain" Value = "6"></asp:ListItem> 

      </asp:RadioButtonList> 

我试图阻止所有radiobuttonlists都选择“否”（值0），所以当我选择（点击）其中一个时，我需要知道他们都选择了什么值，但我点击了。

 $('.tbiDiagnosis input:radio').click(function(e) { 

      if ($(this).val() == 0) { 

       //selector is obviously incorrect, how would I do it here? 
       if ('.tbiDiagnosis input:checked:not($this)).val() > 0).length == 0) 
        e.preventDefault(); 

      } 

     }); 

谢谢。

这是有点不清楚你以后的事情，也许你可以更详细地解释你的事情。我认为您可以通过按值过滤属性[value='0']来查看您要查找的内容，请参阅下面的示例（未经测试）。我希望这有帮助。

$('.tbiDiagnosis input:radio').click(function(e) { 

    if ($(this).val() == 0) { 
     var checked = $(".tbiDiagnosis input:checked"); 
     var filtered = checked.not(checked.find("[value='0']")); 

     if (filtered.length == 0) 
      e.preventDefault(); 

    } 

});
