在ASP.NET中我们经常需要输出一些JS脚本，比如弹出一个警告窗口，返回到历史页面等JS功能，我看到网上好多这方面的代码，以下代码是其中之一。
整个程序的代码如下：
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI;
/// <summary>

/// </summary>
/// <param name="js">窗口信息</param>
public static void Alert(string message, Page page)
{
#region
string js = @"<Script language='JavaScript'>
alert('" + message + "');</Script>";
//HttpContext.Current.Response.Write(js);
if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "alert"))
{
page.ClientScript.RegisterStartupScript(page.GetType(), "alert", js);
}
#endregion
}
/// <summary>

/// </summary>
/// <param name="message">消息内容</param>

public static void AlertAndRedirect(string message, string toURL, Page page)
{
#region
string js = "<script language=javascript>alert('{0}');window.location.replace('{1}')</script>";
//HttpContext.Current.Response.Write(string.Format(js, message, toURL));
if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "AlertAndRedirect"))
{
page.ClientScript.RegisterStartupScript(page.GetType(), "AlertAndRedirect", string.Format(js, message, toURL));
}
#endregion
}

{
#region

</Script>";
//HttpContext.Current.Response.Write(string.Format(js, value));

{
page.ClientScript.RegisterStartupScript(page.GetType(), "GoHistory", string.Format(js, value));
