c# - 使用响应对象创建子页面弹出窗口会破坏父页面的格式

Question

我有一个网页，从中生成一个带有响应对象的弹出窗口，以创建/下载电子名片。它按预期工作，但是我的父页面上的字体大小变得很大，并且只有当我刷新页面时才恢复到原始状态。我该如何解决这个问题？

我对 vcard 弹出窗口的调用:

 Response.Write(@"<script language = 'Javascript'>var" +
                        @" win=window.open('vCard.aspx',null,'width=50,height=50," +
                        @"top=100,left=100','true');</script>");

创建电子名片:

 public static void VCard(HttpResponse response)
    {
        response.Clear();
        response.Charset = "";
        response.ContentType = "text/x-vCard";
        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

            {
                response.AddHeader("content-disposition", "attachment; filename=" + usr.SamAccountName);

                stringWrite.WriteLine("BEGIN:VCARD");
                stringWrite.WriteLine("VERSION:2.1");
                //Name
                stringWrite.WriteLine("N:" + usr.LastName + ";" + usr.FirstName
                    );
               //removed other vcard lines....

                //vCard End
                stringWrite.WriteLine("END:VCARD");
                response.Write(stringWrite.ToString());
                response.End();
            }
    }

在响应完全形成并发送回浏览器之前使用Response.Write将导致字符串被写入流的前面。

实际上有一个特定的方法可以满足这种需求，ClientScriptManager.RegisterClientScriptBlock:

ClientScript.RegisterClientScriptBlock(this.GetType(), "scriptKeyNameCanBeAnythingYouWant", "var
                    @" win=window.open('vCard.aspx',null,'width=50,height=50," +
                    @"top=100,left=100','true');", true);
