javascript - Prototype rewrite of jQuery function -

i'm bit of jquery monkey , i've had site dropped on me need use simple function open links rel="external" in separate window.

in jquery this:

// make links rel=external open in new window/tab $(function() {     $('a[rel*=external]').click( function() {         window.open(this.href);         return false;     }); }); 

how set same function in prototype triggered unobtrusively on links rel=external attached them?

edit:

following advice of 3 responses below final code is:

    $(document).on('dom:loaded', function() {     $$('a[rel*=external]').invoke('on','click', function(event) {         window.open(this.href);         event.stop();     }); }); 

thanks all!

event.observe(window, 'load', function() {     $$('a[rel*=external]').each(function(item) {         $(item).observe('click', function(event) {             window.open(this.href);             event.stop();         });     }); }); 

and here's demo.
