asp.net后台如何输出js脚本使用什么方法可以实现

用page.clientscript.registerstartupscript方式实现

代码为：

/**//// <summary>
/// 弹出javascript小窗口
/// </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>
/// 弹出消息框并且转向到新的url
/// </summary>
/// <param name="message">消息内容</param>
/// <param name="tourl">连接地址</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
}

/**//// <summary>

/// </summary>
/// <param name="value">-1/1</param>
public static void gohistory(int value, page page)
{
#region
string js = @"<script language='javascript'>
history.go({0});
</script>";
//httpcontext.current.response.write(string.format(js, value));
if (!page.clientscript.isstartupscriptregistered(page.gettype(), "gohistory"))
