How to make a link title the same as its URL using jQuery?

Question

My goal is to make the title of every external link equal to its href attribute.

My question is, how can I make the title variable available to the attr function?

$('a').filter(function() {

 var title= $(this).attr('href');
 return this.hostname && this.hostname !== location.hostname;

 })
 .removeAttr('target')
 .attr('rel', 'external')
 .attr('title', title);

$('a[rel="external"]').click( function() {
    window.open( $(this).attr('href') );
    return false;
});

I think I somehow have it backwards, and the answer is in attr(key, fn)

$('a').each(function() {
    var href = $(this).attr('href');
    if(this.hostname && this.hostname !== location.hostname) {
        $(this).removeAttr('target')
               .attr('rel', 'external')
               .attr('title', href)
               .click(function() {
                   window.open(href);
                   return false;
               });
    } 
});
