    <p>Trying to get my feet wet with RxJS, specifically with rx.jquery. I found a little tutorial <a href="https://npmjs.org/package/rx-jquery" rel="nofollow">here</a> and tried to set it up as follows. It's supposed to take what you type and offer suggestions, pulled from Wikipedia. The call to Wikipedia is successful (I see in Chrome's Network debugging window), but the app gives me an error:</p> <blockquote> <p>Uncaught TypeError: Object #&lt;Object> has no method 'subscribe'</p> </blockquote> <p>I've tried several versions of jQuery (1.8.3, 1.10.2, 2.0.3), and that makes no difference. Bootstrap doesn't seem to be an issue, either. I see almost no mention of rx.jquery here (and there's no tag for it), so I don't know whether it's maybe not ready for prime-time or what. I have pulled the most recent rx.* libs, as older ones were giving me different errors.</p> <p>Of course, I can't rule out that I've just bungled something. But it's not jumping out at me.</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;title&gt;Reactive Elements&lt;/title&gt; &lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt; &lt;meta name="apple-mobile-web-app-capable" content="yes" /&gt; &lt;link href="/lib/bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css" /&gt; &lt;script src="/lib/jquery-1.8.3.min.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="container"&gt; &lt;div class="page-header"&gt; &lt;h1&gt;Reactive Extensions &lt;small&gt;in JavaScript&lt;/small&gt;&lt;/h1&gt; &lt;/div&gt; &lt;input id="textInput" type="text" class="form-control"/&gt; &lt;ul id="results"&gt;&lt;/ul&gt; &lt;/div&gt; &lt;script src="/lib/rx.min.js"&gt;&lt;/script&gt; &lt;script src="/lib/rx.binding.min.js"&gt;&lt;/script&gt; &lt;script src="/lib/rx.time.min.js"&gt;&lt;/script&gt; &lt;script src="/lib/rx.jquery.min.js"&gt;&lt;/script&gt; &lt;script&gt; $(function () { var throttledInput = $('#textInput'). keyupAsObservable(). map(function (ev) { return $(ev.target).val(); }). filter(function (text) { return text.length &gt; 2; }). throttle(500). distinctUntilChanged(); function searchWikipedia(term) { return $.ajaxAsObservable({ url: 'http://en.wikipedia.org/w/api.php', data: { action: 'opensearch', search: term, format: 'json' }, dataType: 'jsonp' }); } var suggestions = throttledInput.flatMapLatest(function (text) { console.debug('Searching wiki', text); return searchWikipedia(text); }); var selector = $('#results'); suggestions.subscribe( function (data) { console.debug('Data!', data); selector.empty(); $.each(data[1], function (_, text) { $('&lt;li&gt;' + text + '&lt;/li&gt;').appendTo(selector); }); }, function (e) { console.debug("ERROR!", e); selector.empty(); $('&lt;li&gt;Error: ' + e + '&lt;/li&gt;').appendTo('#results'); } ); }); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    3. COI tested this code with the latest versions of Rx and it works correctly (except for $.each, which is throwing an exception). The only thing I can think of this that one of the Rx libs is not being loaded correctly, or you that you may be using an older version that does not have one of the functions you are trying to use.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
