条件验证问题？

Question

我正在尝试为FormView中的RadioButtonList控件设置条件验证。希望有人能发现我的错误。只有在ThirdPartyInfoTextBox具有文本值且无论rbMTA检查状态如何时，才会禁用验证程序。如果选中rbMTA（0）并且启用了rbMTA（1），我正在寻找要禁用的验证器。

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript">
    function ToggleValidator() {
        var rb = document.getElementById("<%=fvMTAReq.FindControl("rbMTA").ClientID%>");
        var valName = document.getElementById("<%=fvMTAReq.FindControl("RequiredFieldValidator9").ClientID%>");
        if (rb.getElementsByID("rbMTA").checked) {
            ValidatorEnable(valName, false);
        }
        else {
            ValidatorEnable(valName, true);
        }
    }
</script>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:FormView ID="fvMTAReq" runat="server" DataKeyNames="RID" DataSourceID="sqldsMTA" DefaultMode="Insert" HorizontalAlign="Left">
    <InsertItemTemplate>
        <asp:RadioButtonList ID="rbMTA" runat="server" SelectedValue='<%# Bind("ThirdParty") %>' onclick="ToggleValidator()">
            <asp:ListItem Selected="false" Value="true">Yes, I confirm that this material is not subject to an agreement nor was it provided to my lab and/or the Danforth Center by another party.</asp:ListItem>
            <asp:ListItem Value="false">No. Explanation:</asp:ListItem>
        </asp:RadioButtonList>
        <asp:TextBox ID="ThirdPartyInfoTextBox" runat="server" Text='<%# Bind("ThirdPartyInfo") %>' TextMode="MultiLine" Rows="5" Columns="40"/>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator9" runat="server" ValidationGroup="Validation1" ErrorMessage="" Text="*Required*"
            ControlToValidate="ThirdPartyInfoTextBox" ValidateEmptyText="true" CssClass="RequiredField">
        </asp:RequiredFieldValidator>
        <br />
        <br />
        <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" ValidationGroup="Validation1" CommandName="Insert" Text="Submit" />
        &nbsp;<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" />
    </InsertItemTemplate>

您犯了很多语法错误。使用以下内容。

function ToggleValidator() {
        var rb = document.getElementById('<%=fvMTAReq.FindControl("rbMTA").ClientID%>');
        var valName = document.getElementById('<%=fvMTAReq.FindControl("RequiredFieldValidator9").ClientID%>');
        if (document.getElementByID("rbMTA").checked) {
            ValidatorEnable(valName, false);
        }
        else {
            ValidatorEnable(valName, true);
        }
    }

你忘了逃避引号，在if条件下，你输了一个错字。

同时将ClientIDMode添加到Static到控件。
