add to href value of a link using jquery

Question

How do i add some address to the value of the link below using jquery? like http://maps.google.com/maps?q=indianapolis

<div class="driving-directions-link">
<a href="http://maps.google.com/maps?q=">Get Direction</a>
</div>

Answer 1

$("div.driving-directions-link > a").prop("href", function (index, oldHref) {
    return oldHref + "indianapolis";
});

Check out .prop, which can take a function where oldHref is well, the old href.
