Vue Js Detect user switches tabs or leaves the page
Vue Js Detect User Switches Tabs or Leaves the Page: Vue.js is a JavaScript framework that can be used to build reactive web applications. To detect when a user switches tabs or leaves the page, you can use the Page Visibility API
in JavaScript.
The Page Visibility API provides two events: visibilitychange
and beforeunload
. The visibilitychange
event is fired when the user switches tabs, minimizes the browser window, or switches to another application. The beforeunload
event is fired when the user navigates away from the page or closes the browser window.
You can use Vue.js to listen for these events and perform any necessary actions, such as pausing a video or saving a form before the user leaves the page. This can be achieved by attaching event listeners to the window object or by using Vue's built-in event handling mechanisms.

How can you use Vue.js to detect when a user switches tabs or leaves the page of a web application?
This code creates a Vue application with a message displayed on the page. It listens for changes in visibility and updates the message based on whether the user is on the page or has switched to another tab or left the page. When the page is hidden, the message is changed to "Goodbye, world!" and when the page is visible again, the message is changed to "Welcome back!". The event listeners are added in the mounted lifecycle hook and removed in the beforeDestroy lifecycle hook to prevent memory leaks.
