Question

我有一个asp.net webform，其中有一个隐藏字段的页面。当用户以太网从下拉列表中选择一个选项而另一个选择单选按钮时，会显示其中一个字段，我的工作正常。如果首先不显示字段，则验证不会启动（这是正确的）。我的问题是，当用户导航回页面并单击我的“下一步”按钮时，根本不会发生任何事情。我已经确定了该页面现在试图验证的原因，我不知道如何阻止它。

HTML for下拉列表

<div class="form-group">
    <asp:Label ID="Step03WebTypeLabel" class="col-sm-4 control-label" runat="server" Text="Website type *" AssociatedControlID="Step03WebTypeDD"></asp:Label>

            <asp:ListItem Value="Content only (With contact us page)">Content only (With contact us page)</asp:ListItem>
            <asp:ListItem Value="Content only (Without contact us page)">Content only (Without contact us page)</asp:ListItem>

单选按钮的HTML

<div class="form-group" id="hiddenSpecificPages" style="display: none">
    <asp:Label ID="Step03SpecificPagesLabel" class="col-sm-4 control-label" runat="server" Text="Please specify all specific page URL's *" AssociatedControlID="Step03SpecificPagesField"></asp:Label>
    <div class="col-sm-5" style="padding-right: 0px">
        <asp:TextBox ID="Step03SpecificPagesField" runat="server" class="form-control" TextMode="MultiLine" Rows="10" style="max-width: 100%"></asp:TextBox>
    </div>
    <div class="col-sm-offset-4 col-sm-8">
        <asp:RequiredFieldValidator Display="Dynamic" runat="server" ID="reqStep03SpecificErrorMessage" SetFocusOnError="true" ForeColor="Red" ControlToValidate="Step03SpecificPagesField" ErrorMessage="Please list all the page URL's you would like us to look at." />
    </div>
</div>

JQuery的

    if ($("#MainContent_Step03WebTypeDD").val() == "Other")
    {
        $("#hiddenOtherField").show();
        ValidatorEnable(document.getElementById("<%= reqStep03OtherField.ClientID %>"), true);
    }
    else {
        $("#hiddenOtherField").hide();
        ValidatorEnable(document.getElementById("<%= reqStep03OtherField.ClientID %>"), false);
        $("#MainContent_Step03OtherField").val('');
    }
$(function ()
{
    $("input[name='ctl00$MainContent$Step03PgSelection']").click(function ()
    {
        if ($("#MainContent_Step03SelectionPgsRadioButton").is(":checked"))
        {
            $("#hiddenSpecificPages").show();
            ValidatorEnable(document.getElementById("<%= reqStep03SpecificErrorMessage.ClientID %>"), true);
        }
        else
        {
            $("#hiddenSpecificPages").hide();
            ValidatorEnable(document.getElementById("<%= reqStep03SpecificErrorMessage.ClientID %>"), false);
        }
    });
});

将我的JQuery变为：

$(function () {
            $("#MainContent_Step03WebTypeDD").change(function ()
            {
                ToggleDropdown();
            });

            ToggleDropdown();
        });

        function ToggleDropdown() {
            if ($("#MainContent_Step03WebTypeDD").val() == "Other")
            {
                $("#hiddenOtherField").show();
                document.getElementById("<%=reqStep03OtherField.ClientID%>").style.visibility = "visible"; 
                document.getElementById("<%=reqStep03OtherField.ClientID%>").enabled = true;
            }
            else {
                $("#hiddenOtherField").hide();
                document.getElementById("<%=reqStep03OtherField.ClientID%>").style.visibility = "hidden";
                document.getElementById("<%=reqStep03OtherField.ClientID%>").enabled = false;
                $("#MainContent_Step03OtherField").val('');
            }
};

 $(function ()
        {
            $("input[name='ctl00$MainContent$Step03PgSelection']").click(function ()
            {
                ToggleSection();
            });

            ToggleSection();
        });

        function ToggleSection()
        {
            if ($("#MainContent_Step03SelectionPgsRadioButton").is(":checked"))
            {
                $("#hiddenSpecificPages").show();
                document.getElementById("<%=reqStep03SpecificErrorMessage.ClientID%>").style.visibility = "visible";
                document.getElementById("<%=reqStep03SpecificErrorMessage.ClientID%>").enabled = true;
            }
            else
            {
                $("#hiddenSpecificPages").hide();
                document.getElementById("<%=reqStep03SpecificErrorMessage.ClientID%>").style.visibility = "hidden";
                document.getElementById("<%=reqStep03SpecificErrorMessage.ClientID%>").enabled = false;
                $("#MainContent_Step03SpecificPagesField").val('');
            }
        };
