一）简单点的
如要在一个按钮上增加认证脚本，可以这样
<%@ 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>
注意关键的地方btnSubmit.Attributes.Add("onclick","return fffkkk();");这句话，就相当于在静态页面标签上添加 “onclick = “return fffkkk();” 一样
二）复杂一点的
有的时候我们要在DataGrid的删除列上添加认证，可以这样
首先建一个DataGrid，然后给她增加一个删除列
<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>
然后在DataGrid 的ItemDataBound事件中这样写
Private Sub DataGrid1_ItemDataBound
(ByVal sender As Object, ByVal e As DataGridItemEventArgs)
Handles DataGrid1.ItemDataBound
Dim l As LinkButton
If e.Item.ItemType = ListItemType.Item Or
e.Item.ItemType = ListItemType.AlternatingItem Then
l = CType(e.Item.Cells(0).FindControl("cmdDel"), LinkButton)
l.Attributes.Add("onclick", "return getconfirm();")
End If
End Sub
Getconfirm()函数和第一个是一样的
function getconfirm()
{
if (confirm("Do you want to delete record?")==true)
return true;
else
return false;
} 在ASP.NET中使用JavaScript脚本的方法
