分享ASP.NET中javascript验证函数调用问题
正在学习《ASP.NET技术内幕》第三章，我在做例题3-19时碰见难关，面思不得其解，请高手指点。（我用C#)改写了源程序，但其它都没有改动。
这个页面在运行时，客户检验函数老是出现错误，javascript不熟，只是照抄VB的格式，中间估计有问题，但我不知道怎么改，还望各路高手指点。
整个页面源代码如下：
<script runat=server language =c#>
void Button_Click(object s,EventArgs e)
{
if (IsValid)
Response.Redirect("ThankYou.aspx");
}
void CustomValidator_ServerValidate(object s,ServerValidateEventArgs e)
{
string strValue;
strValue = e.Value.ToUpper();
if (strValue.IndexOf("ASP.NET UNLEASHED") > -1 )
e.IsValid = true;
else
e.IsValid = false;
}
</script>
<html>
<head>
<script language="javascript">
function CustomValidator_ClientValidate(s,e)
{
var strValue;
strValue = e.value;
if (strValue.indexOf( "ASP.NET UNLEASHED" ) > -1 )
e.IsValid = true;
else
e.IsValid = false;
}
</script>
<title>CustomValidator.aspx</title>
</head>
<body>
<form id="form1" runat=server>
Enter the name of your favorite book:
<br>
<asp:CustomValidator
id="customValid"
ControlToValidate="txtfavBook"
ClientValidationFunction="CustomValidator_ClientValidate()"
OnServerValidate="CustomValidator_ServerValidate"
Display="Dynamic"
Text="You must type ASP.NET Unleashed!"
runat=server/>
<br>
<asp:TextBox
id="txtfavBook"
TextMode="Multiline"
Columns=50
Rows=3
runat=server/>
<p>
<asp:Button
text="Submit!"
Onclick="Button_Click"
runat=server/>
</form>
</body>
</html>

两位正解。
哪位能解释一下CustomValidator_ClientValidate(s,e)中的s,e各是什么类型的参数吗？它们又各代表什么意义？我在调用这个函数的时候并没有传递这两个参数啊？是不是每个事件处理函数都有这两个参数啊？

ClientValidationFunction="CustomValidator_ClientValidate"//去掉"()"
strValue = e.value;
==>strValue = e.Value;
strValue = e.value;
==>strValue = e.Value;
