Question

I want to close a browser window whether it is in open. Am new for javascript so help me to create the below logic using javascript. My JavaScript code is here:

if (myWindow.open() == true) {
    myWindow.close();
} else {
    myWindow=window.open('http://index.html',
                         'popUpWindow',
                         'height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes'
                         );
}

Answer 1

Use closed property to check the window status, but first check whether the window object has been created or not.

var myWindow=null;
if (myWindow && !myWindow.closed) { //exist and is not closed
    myWindow.close();
    myWindow=null; //delete the object
} else { //not exist or is closed
    myWindow=window.open('http://index.html',
                         'popUpWindow',
                         'height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes'
                        );
}
