火angularjs事件时，标签/关闭浏览器 [英] fire angularjs event when tab/browser is closed

问题描述

我想火JS code在angularjs控制器。

I would like to fire js code in angularjs controller.

我有这样的：

$scope.$on('$destroy', function () {
            alert('page1');
        });

这是工作正常，当我从它使用的控制器，但是当我关闭标签/浏览器它不工作的页面导航了。

This is working fine when I'm navigating away from the page which is using that controller but its not working when I'm closing tab/browser.

我是否需要使用一些其他的code火JS code当标签/浏览器是关闭？

Do I need to use some other code to fire js code when tab/browser is closing?

由于提前，Laziale

Thanks in advance, Laziale

推荐答案

从角文档：

$摧毁（）;

删除当前范围（及其所有的孩子）从
  父范围。去除意味着到$电话消化（）将无
  再传播到目前的范围及其子女。同时去除
  表明当前的范围是符合垃圾收集。

Removes the current scope (and all of its children) from the parent scope. Removal implies that calls to $digest() will no longer propagate to the current scope and its children. Removal also implies that the current scope is eligible for garbage collection.

该$ destroy（）方法通常使用的指令，如ngRepeat为
  管理环的展开

The $destroy() is usually used by directives such as ngRepeat for managing the unrolling of the loop.

一个范围被破坏就在一个$破坏事件上播出
  这个范围。应用code可以注册一个$破坏事件处理程序
  这将使它来执行任何必要的清理工作的机会。

Just before a scope is destroyed, a $destroy event is broadcasted on this scope. Application code can register a $destroy event handler that will give it a chance to perform any necessary cleanup.

请注意的是，在AngularJS，也有一个$破坏jQuery的事件，该事件
  可用于清理DOM绑定之前的元素被从取出
  DOM的。

Note that, in AngularJS, there is also a $destroy jQuery event, which can be used to clean up DOM bindings before an element is removed from the DOM.

这只是处理这样的范围本身被破坏的情况下，似乎没有发生时，标签/浏览器，虽然关闭。

This just handles the situation where the scope itself is being destroyed, that does not seem to occur when the tab/browser is closed though.

您将不得不使用较低的水平onunload的方法和onbeforeunload事件来处理这种情况，这里是你可能会发现有用的另一篇文章：

You will have to use lower level methods onunload and onbeforeunload events to handle this situation, here is another post you may find useful:
