问题描述
亲爱的朋友,
我创建了一个在线考试网页.
用户选择开始考试"后,我将打开一个新窗口"并显示问题,但同时又会关闭现有窗口.
但是用户会打开新窗口并从Google那里获取答案.
我也允许用户输入一个单词的答案.
所以我不能阻止按键.
可以针对这个问题提出任何建议吗?
问候

推荐答案
您可以将Javascript Blur事件附加到页面主体,然后使用它向服务器发送取消消息.
这样,当页面失去焦点时,您都可以取消考试.
一种方法是这样的:
You could attach Javascript Blur event to the page body, and use it to send a cancel to the server.
That way, when ever the page looses the focus, you can cancel the exam.
One way to do this is like this:
<body onblur="javascript:window.opener='x';window.close();">
在Chrome中可以使用该功能关闭窗口而不提示.
Which works in Chrome to close the window without prompting.
