to get a popup instead of a new tab you have to set the dimensions of the window. I looked online a while ago and found this function
function PopupCenter(url, title, w, h) {
// Fixes dual-screen position Most browsers Firefox
var dualScreenLeft = window.screenLeft != undefined ? window.screenLeft : screen.left;
var dualScreenTop = window.screenTop != undefined ? window.screenTop : screen.top;
width = window.innerWidth ? window.innerWidth : document.documentElement.clientWidth ? document.documentElement.clientWidth : screen.width;
height = window.innerHeight ? window.innerHeight : document.documentElement.clientHeight ? document.documentElement.clientHeight : screen.height;
var left = ((width / 2) - (w / 2)) + dualScreenLeft;
var top = ((height / 2) - (h / 2)) + dualScreenTop;
var newWindow = window.open(url, title, 'model=yes,menubar=no,status=no,toolbar=no,location=no,width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);
// Puts focus on the newWindow
if (window.focus) {
newWindow.focus();
}
}
I don't remember the source to give them credit. you then call the function like this.
var url = '@Url.Action("FacebookLogin", "Agent")';
PopupCenter(url, "Popup", 800, 600);
I found this function since it determines your window size and sets the window so that it is centered when it opens. Hope this helps.
