无法获取更新面板中使用JavaScript/JQuery检查的ASPX Checkboxlist的值

Question

我在UpdatePanel内有3个弹出窗口。第一个弹出窗口包含RadioButtonList，选择在第二个弹出窗口中生成RadioButtonList。从第二个弹出窗口选择单选按钮时，填充CheckBoxList“chkListSafetyStandards”。点击第三个弹出窗口的关闭按钮时，我希望获得选中的复选框的文本和值。

的ASPX标记如下：

</asp:UpdatePanel> 

在选择页面上的[checked="checked"]标记不会反映的复选框，所以我无法捕捉使用JavaScript选中的复选框。我无法删除UpdatePanel，因为这会导致整个页面重新加载第一个选项卡（我在第二个选项卡中使用此复选框）。请提出可能的解决方案。

〔实施例的你怎么能得到遏制值：

<asp:CheckBoxList ID="chkListSafetyStandards" CssClass="chk-list-custom" runat="server"> 
     <asp:ListItem Text="option 1"></asp:ListItem> 
     <asp:ListItem Text="option 2" Selected="True"></asp:ListItem> 
     <asp:ListItem Text="option 3"></asp:ListItem> 
    </asp:CheckBoxList> 

    <script> 
     function getChecked() { 
      var checked = $('input[id*="chkListSafetyStandards"]:checked'); 
      checked.each(function (index, value) { 
       console.log($(value).attr("id")); 
      }); 
     } 
    </script>
