一）簡單點的
如要在一個按鈕上增加認證指令碼，可以這樣
<%@ Page Language="C#" %>
<SCRIPT language="javascript">
function getconfirm ()
{
if (confirm("Do you want to delete record?")==true)
return true;
else
return false;
}
</SCRIPT>
<script runat="server">
public void Page_Load(Object sender, EventArgs E) {
btnSubmit.Attributes.Add("onclick","return getconfirm ();");
}
void btnSubmit_Click(object sender, EventArgs e) {
Message.Text = "You entered your name as: " + txtName.Text;
}
</script>
<html>
<head>
</head>
<body>
<form runat="server">
Name: <asp:Textbox id="txtName" runat="server"/>
<asp:Button id="btnSubmit" onclick="btnSubmit_Click" runat="server" Text="Submit"></asp:Button><br/>
<asp:Label id="Message" runat="server"/>
</form>
</body>
</html>
注意關鍵的地方btnSubmit.Attributes.Add("onclick","return fffkkk();");這句話，就相當於在靜態頁面標籤上添加 “onclick = “return fffkkk();” 一樣
二）複雜一點的
有的時候我們要在DataGrid的刪除列上添加認證，可以這樣
首先建一個DataGrid，然後給她增加一個刪除列
<asp:DataGrid id="DataGrid1" runat="server">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton id="cmdDel"
runat="server" Text="Delete"
CommandName="Delete" CausesValidation="false">
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
