CustomValidator 问题

Question

Ok iv 在这里和其他一些网站上跟踪了多个 asp CheckBox 的 CustomValidators，但我在实际验证复选框时遇到了一些困难已检查。

虽然我尝试了多种答案，但我特别确定了一个。我已经知道它会显示在验证摘要中，但是当复选框被选中时，它们仍然会显示在摘要中，但它们不是。我不知道我做错了什么，或者我是否遗漏了什么，但我希望多一双眼睛可以帮助我解决我遗漏的问题。

复选框的：

<div class="section">
    <span>2</span>Induction Checklist:
</div>
<div class="inner-wrap">
    <label>Introduction of relevant staff <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbStaffIntro" /></label>
     <label>Comments: <asp:TextBox runat="server" ID="txtStaffIntroComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Location of all Exits <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbExitLocations" /></label>
    <label>Comments: <asp:TextBox runat="server" ID="txtExitLocationComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Evacuation Assembly Point <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbEvacuationPoint" /></label>
    <label>Comments: <asp:TextBox runat="server" ID="txtEvacuationPointComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
     <label>Location of Fire Extinguishers <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbFireExtLocations" /></label>
      <label>Comments: <asp:TextBox runat="server" ID="txtFireExtLocationsComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Location of Fire Hoses <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbFireHoseLoc" /></label>
    <label>Comment: <asp:TextBox runat="server" ID="txtFireHoseLocComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Location of First Aid Kits <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbFirstAidLoc" /></label>
    <label>Comment: <asp:TextBox runat="server" ID="txtFirstAidLocComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
      <label>Location of Male / Female Toilets <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbLooLoc" /></label>
    <label>Comment: <asp:TextBox runat="server" ID="txtLooLocComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Location of Lunch Rooms <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbLuncLoc" /></label>
    <label>Comment: <asp:TextBox runat="server" ID="txtLunchLocComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Explain "No-Smoking" Policy in all Offices and Buildings <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbNoSmoke" /></label>
     <label>Comment: <asp:TextBox runat="server" ID="txtNoSmokeComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Explain and Indicate "No-Go" Zones in Warehouse <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbNoGo" /></label>
    <label>Comment: <asp:TextBox runat="server" ID="txtNoGoComment" /></label>
</div> <!-- end inner-wrap -->

<div class="inner-wrap">
    <label>Other <asp:CheckBox CssClass="HitCheckbox" ValidationGroup="checkList" runat="server" ID="cbOther" /></label>
     <label>Comment: <asp:TextBox runat="server" ID="txtOtherComment" /></label>
</div> <!-- end inner-wrap -->

客户端验证：

<script>
function CheckBoxRequired_ClientValidate(sender, e)
{
    e.IsValid = jQuery(".HitCheckBox input:checkbox").is(':checked');
}
</script>

服务器端验证：

public void Required_ServerValidate(object source, ServerValidateEventArgs args)
{
    args.IsValid = (cbStaffIntro.Checked);
    args.IsValid = (cbExitLocations.Checked);
    args.IsValid = (cbEvacuationPoint.Checked);
    args.IsValid = (cbFireExtLocations.Checked);
    args.IsValid = (cbFireHoseLoc.Checked);
    args.IsValid = (cbFirstAidLoc.Checked);
    args.IsValid = (cbLooLoc.Checked);
    args.IsValid = (cbLuncLoc.Checked);
    args.IsValid = (cbNoSmoke.Checked);
    args.IsValid = (cbNoGo.Checked);
}

自定义验证器：

<!-- Checklist Validation Section cbStaffIntro -->
<asp:CustomValidator runat="server" ID="CustomValidatorSi" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Introduction to relevant Staff Not Completed!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorEl" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Emergancy Exit Locations Not Completed!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorEp" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Evacuation Point Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorFe" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Fire Extinguisher Locations Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorFh" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Fire Hose Locations Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorFa" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="First Aid Locations Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorToilet" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Toilet Locations Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorLr" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="Lunchroom Location Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorNsp" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="No Smoking Policy Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />
<asp:CustomValidator runat="server" ID="CustomValidatorNg" ValidateEmptyText="true" ValidationGroup="checkList" EnableClientScript="true" Display="None" ErrorMessage="'No-Go' Zones Not Covered!" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />

我希望它的工作方式是所有复选框，除了标记为 'Other' 的复选框，需要在验证表单之前选择它。

如前所述，如果不检查它们，它们将显示在验证摘要中。我遇到的问题是为什么它们在检查时仍然在验证摘要中显示为未检查。

我在这里缺少什么？还是我所追求的不是完全可能的？在我忘记我正在为这个项目使用 .NET Framework 4 之前。

编辑： 感谢 Scotty 帮助我解决这个问题。应用提供的修复后，我还必须删除 Javascript 验证，我必须让代码根据需要工作。

您看到来自所有 CustomValidator 的 ErrorMessages，因为您使用相同的服务器端方法 Required_ServerValidate 来验证所有 CustomValidator 控件并且没有动态构建您的 ErrorMessage。

您需要更改逻辑以针对每种情况动态构建错误消息。

首先，删除除一个之外的所有 CustomValidator，然后按如下方式修改代码。

这是一种方法...

ASPX

<asp:CustomValidator runat="server" ID="cvCheckList" ValidationGroup="checkList" EnableClientScript="true" Display="None" OnServerValidate="Required_ServerValidate" ClientValidationFunction="CheckBoxRequired_ClientValidate" />

确保在 ValidationSummary 中使用 DisplayMode="SingleParagraph"，以便 html 正确呈现。

代码隐藏

public void Required_ServerValidate(object source, ServerValidateEventArgs args)
{
    args.IsValid = true;

    var sb = new StringBuilder();
    sb.Append("<ul>");

    if (!cbStaffIntro.Checked)
        AppendErrorMessage(args, sb, "Introduction to relevant Staff Not Completed!");

    if (!cbExitLocations.Checked)
        AppendErrorMessage(args, sb, "Emergency Exit Locations Not Completed!");

    if (!cbEvacuationPoint.Checked)
        AppendErrorMessage(args, sb, "Evacuation Point Not Covered!");

    if (!cbFireExtLocations.Checked)
        AppendErrorMessage(args, sb, "Fire Extinguisher Locations Not Covered!");

    if (!cbFireHoseLoc.Checked)
        AppendErrorMessage(args, sb, "Fire Hose Locations Not Covered!");

    if (!cbFirstAidLoc.Checked)
        AppendErrorMessage(args, sb, "First Aid Locations Not Covered!");

    if (!cbLooLoc.Checked)
        AppendErrorMessage(args, sb, "Toilet Locations Not Covered!");

    if (!cbLuncLoc.Checked)
        AppendErrorMessage(args, sb, "Lunchroom Location Not Covered!");

    if (!cbNoSmoke.Checked)
        AppendErrorMessage(args, sb, "No Smoking Policy Not Covered!");

    if (!cbNoGo.Checked)
        AppendErrorMessage(args, sb, "'No-Go' Zones Not Covered!");

    sb.Append("</ul>");
    cvCheckList.ErrorMessage = sb.ToString();
}

private static void AppendErrorMessage(ServerValidateEventArgs args, StringBuilder sb, string message)
{
    args.IsValid = false;
    sb.AppendFormat("<li>{0}</li>", message);
}

protected void btnSubmit_Click(object sender, EventArgs e)
{
    Page.Validate();
    if (Page.IsValid)
        Response.Redirect("ValidationSuccessful.aspx");
}
