Determine if the current window has already been opened using JavaScript

I am exploring ways to determine if the current page is open in another tab.

After attempting to use window.open(), I found that it returns the current window rather than a different window with the same address. This results in always returning true.

For example, if 'mysite.com' is already open and the user opens a new tab with 'mysite.com', I want to be able to detect this, switch focus to the existing window, and close the current one.

If you have any suggestions or insights on accomplishing this task, please share. My ultimate goal is to consolidate all links into a single tab for a better user experience.

Answer №1

Utilize localStorage events for inter-tab communication to determine if a page has been previously opened. Refer to this solution: https://example.com/a/14792159/60745

Answer №2

When focusing on a single tab within the same browser and machine, attempting to achieve this using pure JavaScript presents challenges. While it is possible to set a cookie on each page of your site during window.onload to track initial visits, there is no foolproof method to remove this cookie when the user navigates away.

Even with the availability of onunload and onbeforeunload events, these triggers do not activate when users navigate away from a site through a link, use the back button, or close the browser window.
