$（窗口）.unload不点火 [英] $(window).unload is not firing

问题描述

我工作的一个MVC剃刀项目和使用jquery我想执行，当用户正在抛弃特定页面的操作方法。

I'm working on an MVC Razor project and by using jquery I want to execute an action method when the user is abandoning a particular page.

该_layout页面已经加载了jQuery库，它有一个脚本的一节。
该页面有如下code：

The _layout page is already loading the jquery library and it has a scripts section. The page has the following code:

@section scripts{
    <script type="text/javascript">

        $(window).unload(function () {
            alert("Handler for .unload() was called.");
        });

    </script>
}

如果我看查看源文件，我可以看到，该脚本被正确添加页眉中。

If I look at the view source I can see that the script is being added correctly in the page header.

现在，当我选择一个书签从页面导航离开我从来没有看到预期的警告。

Now when I navigate away from the page by selecting a bookmark I never see the expected alert.

我是什么失踪？

感谢。

推荐答案

如果您尝试其实一些浏览器，如谷歌浏览器可能会阻止警报在窗口卸载。作为一个用户，我喜欢这个功能。警报每次尝试导航离开页面吮吸：

Actually some browsers such as Google Chrome might block if you attempt to alert in a window unload. As a user I like this feature. Alerting everytime you try to navigate away from a page sucks:

替换警报一的console.log 或别的东西，更少侵入到用户和事件将被称为愉快

Replace the alert with a console.log or something else less intrusive to the user and the event will be happily called.

您可能还需要签出 onbeforeunload 事件。

You might also want to checkout the onbeforeunload event.
