我已经对ASP下拉菜单和复选框进行了一些验证。我在按钮单击上应用了一些jquery验证，但是其代码不起作用。我尝试检查控制台，但没有给我任何错误。请参阅代码以供参考：
<tr>
<td style="padding: 12px;">Current Experience<span style="color: #CF060D;">*</span>
</td>
<td class="cls4">
<asp:DropDownList ID="ddlCurrentExpYears" CssClass="txtfld-popup_DropD1" runat="server"></asp:DropDownList>
<asp:DropDownList ID="ddlCurrentExpMonth" CssClass="mrg1" runat="server"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqCurrentMonths" runat="server" ControlToValidate="ddlCurrentExpMonth" ErrorMessage="Please select Current Experience" InitialValue="Months" SetFocusOnError="true"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td style="padding: 12px;">Total Experience<span style="color: #CF060D;">*</span>
</td>
<td class="cls3">
<asp:DropDownList ID="ddlTotalExpYears" CssClass="txtfld-popup_DropD1" runat="server"></asp:DropDownList>
<asp:DropDownList ID="ddlTotalExpMonths" CssClass="mrg1" runat="server"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqTotalExpMonths" runat="server" ControlToValidate="ddlTotalExpMonths" ErrorMessage="Please select Total Experience" InitialValue="Months" SetFocusOnError="true"></asp:RequiredFieldValidator><span id="lblExp"></span>
</td>
</tr>
<asp:CheckBox ID="chkDisclaimer" runat="server" /><a href="pdfs/footers/Disclaimer.pdf" target="_blank" class="link1">I have read and agree to the terms and conditions mentioned in the disclaimer</a>
另外，请参阅jss提琴供您参考：-http: //jsfiddle.net/95M8S/1/
