| 如何在ASP.NET中使用JavaScript指令碼 | |
|
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> 然後在DataGrid 的ItemDataBound事件中這樣寫 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()函數和第一個是一樣的 function getconfirm() { if (confirm("Do you want to delete record?")==true) return true; else return false; } 這樣就可以了，呵呵，以上是我在編程中從資料裡總結出來的，也許對你有用。 |
