爲什麼ClientValidationFunction功能不能正常工作？

Question

<script type="text/javascript"> 
    function clientValidation(sender, arguments) 
    { 
     if (arguments.value == "hello world") 
      arguments.isvalid = true; 
     else 
      arguments.isvalid = false; 

     alert(arguments.isvalid); 
    } 
</script> 

<asp:Label ID="lblName" runat="server" Text="Enter Your Name" /> 
<asp:TextBox ID="txtbxName" runat="server" />

試試這個，

function clientValidation(sender, arguments) 
{ 
    if (arguments.Value == "hello world") 
    arguments.IsValid = true; 
    else 
    arguments.IsValid = false; 
} 

編輯：設置ControlToValidate屬性。

<asp:CustomValidator ID="CustomValidator1" runat="server" 
     ErrorMessage="You are Not allowed" 
     ClientValidationFunction="clientValidation" 
     ValidationGroup="ValidationSummary1" 
     ControlToValidate="txtbxName"> 
</asp:CustomValidator>
