How to update (append to) an href in jquery?

Question

I have a list of links that all go to a google maps api.

the links already have the daddr (destination) parameter in them as static. I am using Geo-Loca

Answer 1

var _href = $("a.directions-link").attr("href");
$("a.directions-link").attr("href", _href + '&saddr=50.1234567,-50.03452');

To loop with each()

$("a.directions-link").each(function() {
   var $this = $(this);       
   var _href = $this.attr("href"); 
   $this.attr("href", _href + '&saddr=50.1234567,-50.03452');
});
