Question

I have the code below to open a new window whenever user presses F2 key.

$(document).bind('keyup', function(e){
    if(e.which==113) {
        window.open('newPage.htm','_blank','','false');
    }
});

Now, I want to prevent user to open a new window while the previous one is still opened. How can I dot it ?

Answer 1

var opened = null;
$(document).bind('keyup', function(e){
    if (e.which == 113 && (!opened || !opened.window))
        opened = window.open('newPage.htm','_blank','','false');
​});​
