ajax下的javascript

例1、

如果你用的是微软的ajax框架,弹出提示框应该用:
ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "updateScript", "alert('对不起，账号和密码错误');", true);

例2、

protected void LinkButton_DocName_Command(object sender, CommandEventArgs e)//查看文献详情
{
string docID = e.CommandArgument.ToString();
string key = "js";
string javascript = " <script>window.open('DocumentDetail.aspx?docID=" + docID + "','_blank','height=300, width=820,toolbar=no,scrollbars=yes, resizable=yes') </script>";
ScriptManager.RegisterStartupScript(GridView1, GridView1.GetType(), key, javascript, false);
}

P.S.

public static void OpenerReload(Page page, string key)

        {

            Type cstype = page.GetType();

            ClientScriptManager cs = page.ClientScript;

            if (!cs.IsStartupScriptRegistered(cstype, key))

            {

                String cstext = "window.opener.window.document.forms(0).submit();window.opener.location.href=window.opener.location.href;";//window.opener.location.reload();";

                cs.RegisterStartupScript(cstype, key, cstext, true);

            }

        }
