I needed to obtain a list of Omeka Exhibits to display in a non-Omeka website. The following Javascript provided a list of the titles and descriptions.

 

 

<!DOCTYPE HTML>
<html>
<body>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script>

    var json_obj = JSON.parse(Get('http://yoururl/api/exhibits/'));
    for (i = 0; i <  json_obj.length; i++) {
      exhibit = json_obj[i];
      document.write('<h3>' + exhibit.title + '</h3>');
      document.write('<p>' + exhibit.description + '</p>' );
    }

function Get(yourUrl){
    var Httpreq = new XMLHttpRequest(); // a new request
    Httpreq.open("GET",yourUrl,false);
    Httpreq.send(null);
    return Httpreq.responseText;          
}
  </script>

</body>
</html>
