Firefox window.opener问题

[英]Firefox window.opener issue

原文 2009-06-03 10:36:57 1 2 javascript/ firefox/ new-operator/ tabs/ window.opener

"window.opener" works fine in both IE and Firefox as long as 'Open in New Tab' is used from the right-click menu; 只要在右键菜单中使用“在新标签中打开”，“window.opener”在IE和Firefox中都能正常工作; Error console says "window.opener" is null. 错误控制台说“window.opener”为空。 Is there any other way the opener can be accessed? 有没有其他方式可以访问开启者？

Edit: Error console says "window.opener" is null only when "Open in New Tab" is clicked. 编辑：错误控制台说“window.opener”仅在单击“在新标签页中打开”时为空。 For all other cases, there is no such error. 对于所有其他情况，没有这样的错误。 Hence, what i would like to know is if an alternate other than "window.opener" exists. 因此，我想知道的是，是否存在除“window.opener”之外的替代。

2 个解决方案

window.opener only works if the window (or tab, if it was diverted into a tab) was opened with window.open or via a target attribute or similar. window.opener仅在窗口（或选项卡，如果它被转移到选项卡中）使用window.open或通过target属性或类似物打开时才有效。 In particular, the UI never sets the opener of a window. 特别是，UI从不设置窗口的开启者。
