javascript - Asp 自定义验证器在 IE-11 中不起作用

Question

我正在使用兼容性边缘模式将应用程序从 IE 9 迁移到 IE 11。asp 自定义验证器和必填字段验证器在 IE 11 中不起作用，但 page.isValid() 始终返回 true。但在 IE 9 中运行良好。

示例代码:

<asp:DropDownList ID="cboType" onChange="fnInvalid(this,'hidTypeValid');getSelectedValue('cboType','hidliab');changeOptions(document.forms[0].hidliab,document.forms[0].cmbLiability,document.forms[0].hid_liab,document.forms[0].HIDSERLIAB);" runat="server" name="cbotype"AutoPostBack="true"></asp:DropDownList>
                                                            <asp:RequiredFieldValidator ID="VreqvalidateType" runat="server" Display="None" ControlToValidate="cboType" ErrorMessage="-Case Type should not be blank" InitialValue="Choose"></asp:RequiredFieldValidator>

<asp:CustomValidator ClientValidationFunction="fnInvalidSelection" ID="VcustTypeValid"
runat="server" Display="None" ControlToValidate="cboType" ErrorMessage="-Case Type should have valid selection."></asp:CustomValidator>

<asp:CustomValidator ClientValidationFunction="fnTypeFileClass" ID="VcusTypeFile" runat="server" Display="None" ControlToValidate="cboType" ErrorMessage="- Case File Classification should not be empty."></asp:CustomValidator>

 <asp:CustomValidator Enabled="false"ClientValidationFunction="fnTypeCaseHandler"ID="VcusTypeCaseHandler" runat="server" Display="None" ControlToValidate="cboType"ErrorMessage="- Case Handler 1  should not be empty."></asp:CustomValidator>

Javascript:

<pre lang="C#">function fnTypeCaseHandler(sender,args)
    {
    var s = args.Value;
    args.IsValid = true;
        if (s!="K")
        {
        var handler1= document.frmCaseDetails.cmbHandler1.value;
        if (handler1 =="Choose")
        {
            args.IsValid = false;
        }
        }
    return args.IsValid;
    }

function fnTypeFileClass(sender,args)
    {
    var s = args.Value;
    args.IsValid = true;
        if (s!="K")
        {
        var file = document.frmCaseDetails.cmbFileClass.value;
        if (file =="Choose")
        {
            args.IsValid = false;
        }
        }
    return args.IsValid;
    }

这是因为我们提出了 IE-11 问题 <meta>在页面标题部分添加与 IE-11 兼容的标签效果很好。
