JS does not work if the site is in a subfolder

I did a bit of old-school javascript debugging in combination with research on the $.ajax function and I think I found the root cause - the "url" option in the $.ajax function was failing because it is a relative url like "/taxonomy_quick_find/0/125". When I hardcoded the base url of my test system into the "url" it started working properly.

The other thing that helped me discover it was by adding an "error" option to the $.ajax function with some alerts to see that the JSON callback was indeed failing until I changed the url. Not sure what this means - is this a bug?

One more finding - the standard "url" value works ok on another system where the base_url of drupal is the hostname without any extra directories after it. But I had to hardcode the full server name on any systems that use something like http://example.com/cms rather than just http://example.com/.

In taxonomy_quick_find.js, I changed this:

        //Do an JSON callback using the AJAX handler
        $.ajax({
          type: "GET",
          url: "/taxonomy_quick_find/" + delta + "/" + select.value,
          dataType: "json",

to the following with a hardcoded URL:

        //Do an JSON callback using the AJAX handler
        $.ajax({
          type: "GET",
          url: "http://example.com/cms-app/taxonomy_quick_find/" + delta + "/" + select.value,
          dataType: "json",

Like I said, this change is not needed if your drupal system uses a url without any additional directory elements like "cms-app". Hope this helps...
