在歌剧中onbeforeunload [英] onbeforeunload in Opera

问题描述

我正在使用netadictos发布的代码此处。所有我想做的是在用户远离或关闭窗口/标签时显示警告。

I'm using the code that netadictos posted to the question here. All I want to do is to display a warning when a user is navigating away from or closing a window/tab.

netadictos发布的代码似乎在IE7中正常工作，FF 3.0.5，Safari 3.2.1和Chrome，但它在Opera v9.63中不起作用。有人知道在歌剧中做同样的事情吗？

The code that netadictos posted seems to work fine in IE7, FF 3.0.5, Safari 3.2.1, and Chrome but it doesn't work in Opera v9.63. Does anyone know of way of doing the same thing in Opera?

Thx，Trev

推荐答案

onbeforeunload 现在支持基于WebKit引擎的Opera 15，但不支持基于Presto的任何先前版本。

onbeforeunload is now supported in Opera 15 based on the WebKit engine but not in any prior versions based on Presto.
