    <p>I am trying to implement an autocompleter on a nodejs app using nowjs. </p> <pre><code>everyone.now.sendAutocomplete = function(search) { var response = getAutocomplete(search); console.log("response"); console.log(response); }; </code></pre> <p>which calls:</p> <pre><code>function getAutocomplete(search) { console.log(search); var artist = new Array(); request({uri: 'http://musicbrainz.org/ws/2/artist/?query=' + search + '&amp;limit=4', headers: "Musicbrainz Application Version 1"}, function(error, response, body) { par.parseString(body, function(err, result) { var count = result['artist-list']['@']['count']; var artists = result['artist-list']['artist']; // var artist = new Array(); if (count &gt; 1) { artists.forEach(function(a) { var att = a['@']; var id = att['id']; var name = a['name']; var dis = a['disambiguation']; if (dis) { var display = name + " (" + dis + " )"; } else { display = name; } artist.push({'id':id, 'name': name, 'disambiguation':dis, 'label':display, 'value':name, 'category':"Artists"}); }); //everyone.now.receiveResponse(artist); console.log("artist"); console.log(artist); return artist; } else { console.log(artists); var att = artists['@']; var id = att['id']; var name = artists['name']; var dis = artists['disambiguation']; var resp = [{'id':id, 'name': name, 'disambiguation':dis, 'label':name, 'value':name, 'category':"Artists"}]; return resp; // everyone.now.receiveResponse([{'id':id, 'name': name, 'disambiguation':dis, // 'label':name, 'value':name, 'category':"Artists"}]); } }); }); } </code></pre> <p>However, console.log(response) says that response is undefined. I am new to node so the answer is probably simple, but still can't figure it out. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
