c#弹出提示或者弹出提示并跳转应用

1。提示框有两个选择项，点确定跳转，取消停留在原页面
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "", "<script>if(confirm('请登录？')){location.href='login.aspx'};</script>", false);

 

2.提示框只有一个确定按钮，跳转到指定页面
ScriptManager.RegisterStartupScript(page, this.GetType(), "", "<script>alert('请登录？');location.href='login.aspx'</script>", false);

或者是：

<script language="JavaScript">alert('提示信息');-------------------------提示框内容location.href='https://125.69.90.54/';-----------------------点击按钮后跳转页面url

document.onmousedown=click</script>

3、Response.Write
("<script>alert('查询语句执行出错！');window.location.href=DisplayData.aspx</script>");

4、ClientScript.RegisterStartupScript(this.GetType(), "", " <script lanuage=javascript> alert('');location.href='';</script>"); 

5、System.Web.HttpContext.Current.Response.Write(String.Format("<script language=\"javascript\">alert(\"{0}\");window.location.replace(\"{1}\")</script>", strMessage, strRedirectUrl));

6、Page.ClientScript.RegisterStartupScript(this.GetType(), "d", "alert('请先登录！');location='../login.aspx';", true);

 

无刷新弹出警告：       

ScriptManager.RegisterStartupScript(this.Page, this.GetType(),"onekey", "alert('弹出')", true);

而以下方法，会刷新弹出，比较难看

Response.Write("<script>alert('弹出')</script>");

ClientScript.RegisterStartupScript(this.Page, this.GetType(),"onekey", "alert('弹出')", true);
