其他技术

某些弹出窗口由Cookie控制，因此，如果您为该域设置了正确的Cookie值，则该弹出窗口可能不再显示。这可以是手动完成或通过启用用户Cookie行为模式。

为此，请访问网页并打开浏览器的开发人员工具，以便您可以查看网页上存在哪些cookie。现在关闭弹出窗口。如果出现新的cookie，请刷新页面。如果不再显示弹出窗口，请复制显示的Cookie的详细信息，并将其添加到您的自定义Cookie。但是，最好给它一个较长的有效期，也许是10年，这样就不会删除Cookie。

另一个可能的解决方案是使用 搜索引擎 用户代理，通过设置“ request as”参数。根据网站的编写方式，可能会导致弹出窗口不显示。
