如何在ASP.NET中使用JavaScript脚本 | |
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; } 这样就可以了,呵呵,以上是我在编程中从资料里总结出来的,也许对你有用。 |
