Code that resembled the below is how I used to open new windows before I
started using jQuery Note, this completely avoids use of the target
attribute.
function wireNewWindows(){
if(document.getElementsByTagName){
var anchors = document.getElementsByTagName("a");
for(var i = 0; i < anchors.length; i++){
var node = anchors[i];
if(node.getAttribute('rel') == 'external' ||
node.getAttribute('rel') == 'nofollow'){
node.onclick = function(){
var url = this.href;
window.open(
url,
'newWin','width=700,height=500,Menubar=yes,Toolbar=no,Location=no'
);
return false;
}
}
}
}
}
