Below is my code to open a new popup window :

Answer 1

Here is my suggestion:

function authorize(callback) {

if(!document.authorize) {
    console.log('Opening authorization window...');
    document.authorize = window.open('popup.html','tw','width=300,height=200');
}

if(document.authorize.closed) {
    console.log('Authorization window was closed...');
    setTimeout(callback,0); 
} else {
    setTimeout(function(){
        console.log('Authorization window still open...');
        authorize(callback);
    },1000);    
}

return false;
}


function test() {
    authorize(function(){
      alert('teste');
    });
}
