问题 I'm trying to call a method in the beforeunload event handler. It seems like the browser is closing too fast.

当用户关闭浏览器时弹一个确认对话框，当程序自动关闭这个页面时无需弹确认对话框

最近工作中有个需求：当用户关闭浏览器时弹一个确认对话框，当程序自动关闭这个页面时无需弹确认对话框。 现在把做完的功能记录下来。 这里用到onbeforeunload事件： 目前三大主流浏览器中firefox和IE都支持onbeforeunload事件,opera尚未支持。 关闭浏览器时会触发onbeforeunload事件，当程序自动关闭这个页面时则调用u3dCloseWindow()方法。 js代码如下： <script type="text/javascript"> var flag = true; function u3dCloseWindow() { flag = false; 　 window.opener = null; window.open(' ', '_self', ' '); window.close(); } window.onbeforeunload = function() { if(flag) { return "未答完时请勿关闭窗口，否则成绩将不做保存！"; } } </script> 来源： oschina 链接： https://my.oschina.net/u/554982/blog/64932

The draggable div is absolutely positioned and matches the mouse movements. For this I needed to add 3 event listeners to document.body. They are as follows: document.body

Be careful with this, though.

问题 The confirmation dialogues in chrome are not accessible to JAWS screenreader (Version 18.0.2945).
