Class for external links - warning alert

[avbryt]

Hi,
in order to open a warning pop up when leaving page
I have this script:

function Warning() {
window.confirm
var answer = confirm("Wanna leave page?");

if (answer == true)
{
window.location= href;
}
else
{
return false;
}
}

I would like to call a function, with a specific class for all the external links.

function externalLinks() {
var anchors = document.getElementsByTagName('a');
for(var i=0; i<anchors.length;i++) {
if(anchors[i].className) {
if(anchors[i].href && anchors[i].className == "LinkedList") {
anchors[i].target = "_blank"; ;
}
}
}
}


How is it possible to get the class and open the popup?

(and yes I know that a warning popup is annoying... I´m told to do this)

What is the syntax for classname?
