[SOLVED] How to tell if app is running in portal tab or popup window

[Maria]

Hi,

I would like to know the way to determine within the app itself if the app had been opened in the portal tab or if it had been launched in a pop-up window.

Thanks for your help!

When you say within the app itself I assume you mean the front-end JavaScript part. If so you can simply check to see if window.opener exists. If that returns true then the app is running in a window and you can assume it's in a tab if not.

if (window.opener) {
    alert('this app is running in a window');
} else {
    alert('this app is running in a tab');
}
