一、System.Web.UI.ScriptManager.RegisterStartupScript來替代Page.ClientScript.RegisterStartupScript
函數原型：System.Web.UI.ScriptManager.RegisterStartupScript（Contrl control, Type type,string key,string script, bool addScriptTags）;
參數：control要要註冊此段javascript語句的控件ID,如下面示例的按鈕ID btnUnReporttype一般直接用this.GetType()即可
key爲要執行的javascirpt語句起的名字，可以隨便起，類似控件的name屬性script javascript語句addScriptTags爲true時，前邊的script參數可以不用再寫javascript標籤；爲false,則需自己爲script參數添加<script language=’javascript’></script>標籤。
注：要多傳一個Control參數，如果這個control在UpdatePanel裏，則運行腳步，如果這個control不在UpdatePanel則不允許這段腳步。Eg.System.Web.UI.ScriptManager.RegisterStartupScript(btnUnReport, this.GetType(), "unReport", "alert('撤銷上報操作失敗，請勾選要上交的課題！');window.close();", true);
二、註冊DataItem方法
示例：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="WebForm1.aspx.cs" Inherits="WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>無標題頁</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_pageLoading(
function(sender, e)
...{
var dataItem = e.get_dataItems()["<%= this.UpdatePanel1.ClientID %>"]();
alert(dataItem.Name);
});
</script>
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="test" runat="server" Text="test" OnClick="test_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
CODE:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Web.Script.Serialization;
public partial class WebForm1 : System.Web.UI.Page
...{
protected void Page_Load(object sender, EventArgs e)
...{
}
protected void test_Click(object sender, EventArgs e)
...{
JavaScriptSerializer serializer = new JavaScriptSerializer();
ScriptManager.GetCurrent(this.Page).RegisterDataItem(this.UpdatePanel1, "var _f = function(){alert('Hello World!');}; _f;", true);
}
}
三、使用Javascript的非模態對話框彈出提示
Eg.Page.RegisterStartupScript("alert", "<script language='javascript'>window.showModelessDialog(\"javascript:alert('撤銷上報操作失敗，請勾選要上交的課題！');window.close();\",\"\",\"status:no;resizable:no;help:no;dialogHeight:height:30px;dialogHeight:40px;\")</script>");
四、用下面的方法代替Response.Write()： （本人用VS2005通過驗證）
System.Web.UI.ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "click", "alert('Hello Word！')", true);
五、也可用AjaxControlToolkit的ConfirmButtonExtender控件。
六、
1.添加引用
using MagicAjax.UI;
2.response.write改成類似以下語句
string messageContent = "放js語句";
MagicAjax.AjaxCallHelper.Write("alert('" + messageContent + "');");
