EDIT, I think this is what you're looking for:
html:
<a href="http://www.google.com" target="_blank" id="cliccami">Click here</a>
jQuery:
$(document).ready(function() {
$('#cliccami').click(function(e) {
window.open($(this).attr('href'));
e.preventDefault();
});
$('#cliccami').click();
});
In my example (JSFiddle: http://jsfiddle.net/qw9BW/) #cliccami
's click event is captured, alerted, then stopped. then a $.click() is ran on page load to force the click event to happen.
