如何防止弹出的div窗口在按Escape按钮时关闭
问题描述：
我正在使用现有的div作为弹出窗口来输入用户的用户详细信息，例如姓名，地址等.但是当我按下逃逸按钮时，它突然关闭了弹出窗口，而没有检查弹出div中的文本框是否被填充.
我希望这样.如果用户将任何文本框留空，则用户应在按下转义键时收到警报消息.
I am using existing div as a popup to enter a user details like name, address etc. from user. but when i press escape button it suddenly close that popup windows without checking whether or not that textbox inside popup div is filled or not..
i want such that.. user should get alert message on pressing escape key if he / she has left any text box blank.
