Voici une fonction JavaScript qui te permet de le faire.
wloc --> ton lien (ex: "popup.html" )
sWidth_i --> largeur
sHeight_i --> hauteur
function openPopupWindow (wloc, sWidth_i, sHeight_i) {
if (wAddEvent!=null) if (!wAddEvent.closed) {
wAddEvent.focus();
return;
}
var x=parseInt((screen.availWidth-sWidth_i)/2)
var y=parseInt((screen.availHeight-sHeight_i)/2)
wAddEvent = window.open(wloc,'wAddEvent','toolbar=no,locati
on=no,resizable=no,directories=no,status=no,person
al=no,menubar=no,scrollbars=yes,width='+sWidth_i+
',height='+sHeight_i+',left='+x+',top='+y);
wAddEvent.moveTo(x,y);
}
