Output

Let us carry out the following steps to see how the above given code works −

  • Save the above given HTML code as tabs_js_events.html file in your server root folder.

  • Open this HTML file as http://localhost/tabs_js_events.html and the output is displayed as shown below.

  • The example allows switching between tabs and the alert event occurs when the tab becomes visible.
