处理ASP.net中的页面卸载事件 [英] Handle page unload events in ASP.net

问题描述

HI，
该应用程序包含一个aspx页面名称为test1.aspx.每次加载此页面时，我都会在布尔变量(变量名称:isSave)中获取真值或假值.假设如果我从该应用程序中的test1.aspx页导航到其他一些aspx页，则需要检查布尔变量.如果布尔变量为false，我什么也不想做.如果布尔变量为false，则需要显示确认警报框


谢谢

推荐答案

您的意思是，当您尝试不输入消息而不单击按钮提交来浏览时，是否像codeproject一样?

向克里斯询问他如何在此站点上处理该问题，因为它确实满足了您的想法.

当然，仅关闭浏览器窗口就不会受到用户的保护，所以所有这些努力真的值得吗?

You mean like codeproject does when you try to browse away from entering a message without clicking the button to submit?

Ask Chris how he handled that on this site, because it does what I *think* you want to do.

Of course, there''s no protection from the user simply closing the browser window, so is all this effort really worth it?

如果布尔变量为false我不想要做任何事.如果布尔变量为false，则需要显示确认警报框
为什么需要为此处理卸载事件?

您有各种状态管理技术.使用任何一个.尝试Session或QueryString.

if the boolean variable has false i dont want to do anything. if the boolean variable has false i need to show the confirm alertbox
Why you need to handle unload event for this?

You have various state management techniques. Use any one. Try Session or QueryString.
