The URL of a page is accessible through the locationproperty of the window object. If you are visiting a site on the same subdomain as you , then you can get the address via
页面的 URL 可以通过window 对象的location属性访问。如果您正在访问与您位于同一子域中的站点，则可以通过以下方式获取地址
popupWindow.location.href
However, if the popup is from a third party, the same origin policyapplies and you are not allowed to inspect the location.href of the popup. The only ways to bypass the same origin policy would involve cooperation from the third party.
但是，如果弹出窗口来自第三方，则适用同源策略，并且不允许您检查弹出窗口的 location.href。绕过同源政策的唯一方法将涉及第三方的合作。
