How to detect if a browser is blocking a popup with JavaScript?
To detect if a browser is blocking a popup with JavaScript, we can check the closed property of the window.
For instance, we write
const newWin = window.open(url);
if (!newWin || newWin.closed || typeof newWin.closed == "undefined") {
//...
}
to call window.open to open the url.
Then we check if the window object’s closed property is true or undefined or if the window object is falsy.
If any of these are true, then the window is blocked from opening.
Conclusion
