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： 复制代码 代码如下: /**//// <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> /// 回到历史页面 /// </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> /// 刷新打开窗口 /// </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> /// 打开指定大小的新窗体 /// </summary> /// <param name="url">地址</param> /// <param name="width">宽</param> /// <param name="heigth">高</param> /// <param name="top">头位置</param> /// <param name="left">左位置</param> public static void OpenWebFormSize(string url, int width, int heigth, int top, int left, Page page) { #region string js = @"<Script language='JavaScript'>window.open('" + url + @"','','height=" + heigth + ",width=" + width + ",top=" + top + ",left=" + left + ",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> /// 转向Url制定的页面 /// </summary> /// <param name="url">连接地址</param> public static void JavaScriptLocationHref(string url, Page page) { #region string js = @"<Script language='JavaScript'> window.location.replace('{0}'); </Script>"; js = string.Format(js, url); //HttpContext.Current.Response.Write(js); if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "JavaScriptLocationHref")) { page.ClientScript.RegisterStartupScript(page.GetType(), "JavaScriptLocationHref", js); } #endregion } /**//// <summary> /// 打开指定大小位置的模式对话框 /// </summary> /// <param name="webFormUrl">连接地址</param> /// <param name="width">宽</param> /// <param name="height">高</param> /// <param name="top">距离上位置</param> /// <param name="left">距离左位置</param> public static void ShowModalDialogWindow(string webFormUrl, int width, int height, int top, int left, Page page) { #region string features = "dialogWidth:" + width.ToString() + "px" + ";dialogHeight:" + height.ToString() + "px" + ";dialogLeft:" + left.ToString() + "px" + ";dialogTop:" + top.ToString() + "px" + ";center:yes;help=no;resizable:no;status:no;scroll=yes"; ShowModalDialogWindow(webFormUrl, features, page); #endregion } /**//// <summary> /// 弹出模态窗口 /// </summary> /// <param name="webFormUrl"></param> /// <param name="features"></param> public static void ShowModalDialogWindow(string webFormUrl, string features, Page page) { string js = ShowModalDialogJavascript(webFormUrl, features); //HttpContext.Current.Response.Write(js); if (!page.ClientScript.IsStartupScriptRegistered(page.GetType(), "ShowModalDialogWindow")) { page.ClientScript.RegisterStartupScript(page.GetType(), "ShowModalDialogWindow", js); } }
