Question

我有一个模态表单（bootstrap），我使用asp.net RequiredFieldValidtors进行数据输入验证。此验证只应在模态可见时触发，并且用户在模式中输入新值。

我遇到的问题是，当未显示模型表单阻止我的主页接受新数据输入时，验证会触发。我的模态仅用于添加新值，而不是我主页上正常工作流程的一部分。

我已经被困在这两天了，并尝试了许多不同的事情，但是无法理解它。

有关如何在保持RequiredFieldValidator规则不变的情况下处理此问题的任何建议吗？

Answer 1

我已经汇总了一个非常简单的示例，说明了我的应用程序是如何做到这一点的。 Modal只是一个ascx控件，不有一个updatepanel。它实际上只是一个控件变得可见但我们使用CSS和JavaScript使它成为一个模态。同样的逻辑应该仍然适用，因为我已经从一个有效的模态中制作了这个样本。

<强> Modal.ascx

验证器具有ValidationGroup并被禁用。按钮也分配给ValidationGroup：

<div id="approvalModal" style="display: none;">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" Enabled="false"
        ControlToValidate="TextBox1" ValidationGroup="testValidationgGroup" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
    <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="testValidationgGroup" />
</div>

<强> Modal.ascx.vb

在属性中启用验证器：

Partial Class Modal
    Inherits System.Web.UI.UserControl

    Public WriteOnly Property Enable() As Boolean
        Set(value As Boolean)
            RequiredFieldValidator1.Enabled = value
        End Set
    End Property

End Class

PageWithModal.aspx （注意：使用jQuery）

<script>
    function setupTestModal() {
        var modal = $('#approvalModal');
        if (modal.css('display') == 'none') {
            modal.show();
        }
    }
</script>

<asp:Button ID="ShowModal" runat="server" Text="Show Modal" OnClick="ShowModal_Click" />
<uc1:Modal runat="server" ID="testModal" />

<强> PageWithModal.aspx.vb

请注意，单击ShowModal按钮时，验证不会触发。但是，当模态可见时，验证器已启用。

Protected Sub ShowModal_Click(sender As Object, e As EventArgs)
    testModal.Enable = True
    Dim script = String.Concat("setupTestModal();")
    ScriptManager.RegisterStartupScript(Me.Page, Me.Page.GetType(), "Popup", script, True)
End Sub

asp.net隐藏时不验证Modal表单
