用户离开页面时在Seam中结束对话 [英] End Conversation in Seam when the user leaves the page

问题描述

当用户离开页面时，是否可以通过某种方式结束Seam 2中的对话?我知道，我当然可以在导航规则中结束对话(请参见这篇文章 )，但是当用户在浏览器的地址栏中输入网址时，我想结束对话.

Is there some way to end a conversation in Seam 2 when the user leaves the page? I know, that I can of course end a conversation in the navigation rules( see this post), but I want to end a conversation when the user enters an url in the address bar of the browser.

这可以通过Javascript实现吗(例如，使用onbeforeunload)?但是如何通过javascript停止对话?

Could this be achieved via Javascript (for example with onbeforeunload)? But how to stop a conversation via javascript?

您可以使用JavaScript实施onbeforeunload事件，并使用AJAX交流离开该网站的用户并结束所有对话.但是，我不建议您使用此解决方案，因为您不能依赖浏览器上发生的事件，Javascript不是一个好的选择，因为您可以在客户端禁用它(不仅如此，而且浏览器可能会崩溃，网络连接可能会断开，等等.)

You could use JavaScript to implement an onbeforeunload event and use AJAX to communicate the user leaving to the site and end all your conversations. However, I don't recommend you this solution because you cannot rely on a event happening on the browser, Javascript is not a good option, since you can disable it client-side (Not only that, but the browser may crash, the network connection may drop, etc..)

我认为实现此目的的另一种方法是在服务器上设置接缝conversation timeout.您可以尝试减少超时，以便在用户离开您的页面时更快地关闭不活动的会话.

I think an alternative aproach to do this is by setting a seam conversation timeout on the server. You can try and reduce the timeout in order to close inactive conversation faster, when the user leave your page.

配置会话超时时间可以通过components.xml中的以下操作完成:

Configuring the conversation-timeout period can be accomplished through the following in your components.xml:

<core:manager conversation-timeout="700000" />

请注意，对话超时仅影响background对话，foreground对话仅在与您的要求相关的对话超时时才会超时.

Notice that conversation-timeout only affects background conversations, foreground conversation will only timeout when the session times out which is relevant for your requirements.

有关会话超时的更多信息，请参见以下文章.
