What I want to do is to change the size of a window and create a window next to it so they are exactly next to each other. In that sense, I need to position to the new window to the top right part of the screen, the way I am doing it is not working (code is below), I need help :)
function () {
var viewportwidth = document.documentElement.clientWidth;
var viewportheight = document.documentElement.clientHeight;
window.resizeBy(-300,0);
window.open("something.htm",
"mywindow",
"width=300,
height=viewportheight,
left=(viewportwidth - 300),
top=0,
screenX=0,
screenY=0");
}
