asp.net後台如何輸出js腳本使用什麼方法可以實現

 asp.net後台如何輸出js腳本,用page.ClientScript.RegisterStartupScript方式實現,實現示例如下,感興趣的朋友不要錯過

用page.ClientScript.RegisterStartupScript方式實現    代碼為:  代碼如下: /**//// <summary>  /// 彈出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>  /// 彈出消息框並且轉向到新的URL  /// </summary>  /// <param name="message">消息內容</param>  /// <param name="toURL">連接地址</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>  /// 回到歷史頁面  /// </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"))  {  page.ClientScript.RegisterStartupScript(page.GetType(), "GoHistory", string.Format(js, value));  }  #endregion  }    /**//// <summary>  /// 刷新父窗口  /// </summary>  public static void RefreshParent(string url, Page page)  {  #region  string js = @"<Script language='JavaScript'>  window.opener.location.href='" + url + "';window.close();</Script>";  //HttpContext.Current.Response.Write(js);  if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "RefreshParent"))  {  page.ClientScript.RegisterStartupScript(page.GetType(), "RefreshParent", js);  }  #endregion  }      /**//// <summary>  /// 刷新打開窗口  /// </summary>  public static void RefreshOpener(Page page)  {  #region  string js = @"<Script language='JavaScript'>  opener.location.reload();  </Script>";  //HttpContext.Current.Response.Write(js);  if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "RefreshOpener"))  {  page.ClientScript.RegisterStartupScript(page.GetType(), "RefreshOpener", js);  }  #endregion  }      /**//// <summary>  /// 打開指定大小的新窗體  /// </summary>  /// <param name="url">地址</param>  /// <param

",location=no,menubar=no,resizable=yes,scrollbars=yes,status=yes,titlebar=no,toolbar=no,directories=no');</Script>";  //HttpContext.Current.Response.Write(js);  if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "OpenWebFormSize"))  {  page.ClientScript.RegisterStartupScript(page.GetType(), "OpenWebFormSize", js);  }  #endregion  }      /**//// <summary>  /// 轉向Url制定的頁面  /// </summary>  /// <param name="url">連接地址</param>  public static void JavaScriptLocationHref(string url, Page page)  {  #region  string js = @"<Script
