beforeDestroy生命周期钩子函数在Vue组件销毁之前被调用。在这个钩子函数中,你可以执行一些清理操作,比如取消订阅、解绑事件等,以防止内存泄漏。\[1\]在使用缓存的情况下,离开当前路由不会直接调用beforeDestroy,需要使用路由钩子函数主动调用beforeRouteLeave来销毁组件。\[1\]如果在Vue项目中使用了keep-alive进行缓存,beforeDestroy钩子函数会失效,需要在deactivated钩子函数中进行清理操作。\[2\]另外,如果将事件绑定到window上,比如scroll事件,需要在beforeDestroy钩子函数中解绑事件,以免在其他页面也受到该事件的影响。\[3\]
