[Plugin: Query Multiple Taxonomies] Need code to generate query URL

Hi

I am trying to include post reorder function on my qmt results page using
jquery. below is the code that generates the output url.

window.location.href = "<?php echo home_url(); ?>/reorder-posts/?o="+str;

does anyone know what code I could use to generate the url created by a QMT query within this code.
