Question

In Javascript, we can use window.open() to open a new browser window or tab.
But if a tab is already open, it should highlight that only. It should not open duplicate tabs.
How to do that?

Answer 1

The second argument of window.open(strUrl, strWindowName[, strWindowFeatures]); is the window name. if you specify that parameter, to anything other than “_blank” it will refer to the already opened tab/window.

For instance:

window.open('/about', 'newwindow');

and

window.open('/contact', 'newwindow');

will open the page in an already opened window/tab.
