HTML:
<a href="#" class="yourlink">Click Here</a>
JS:
$('a.yourlink').click(function(e) {
e.preventDefault();
window.open('http://yoururl1.com');
window.open('http://yoururl2.com');
});
window.open
also can take additional parameters. See them here: http://www.javascript-coder.com/window-popup/javascript-window-open.phtml
You should also know that window.open is sometimes blocked by popup blockers and/or ad-filters.
Addition from Paul below: This approach also places a dependency on JavaScript being enabled. Not typically a good idea, but sometimes necessary.
