<p><em>Converse.js</em> implements <aclass="reference external"href="https://en.wikipedia.org/wiki/Xmpp">XMPP</a> as its messaging protocol, and therefore needs
to connect to an XMPP/Jabber server (Jabber is really just a synonym for XMPP).</p>
<p>Your website and <em>Converse.js</em> use <aclass="reference external"href="https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol">HTTP</a> as protocol to communicate with
the webserver. HTTP connections are stateless and usually shortlived.</p>
<p><aclass="reference external"href="https://en.wikipedia.org/wiki/Xmpp">XMPP</a> on the other hand, is the protocol that enables instant messaging, and
its connections are stateful and usually longer.</p>
<p>To enable a web application like <em>Converse.js</em> to communicate with an XMPP
server, we need a proxy in the middle that can act as a bridge between the two
protocols.</p>
<p>This is the job of a connection manager. A connection manager can be either a
standalone application or part of an XMPP server. <aclass="reference external"href="http://www.ejabberd.im">ejabberd</a> for example,
includes a connection manager (but you have to enable it).</p>

<p>The domain of the <em>Converse.js</em> demo is <em>conversejs.org</em>, but the domain of the connection manager is <em>opkode.im</em>.
HTTP requests are made by <em>Converse.js</em> to the connection manager via XmlHttpRequests (XHR).
Until recently, it was not possible to make such requests to a different domain
than the one currently being served (to prevent XSS attacks).</p>
<p>Luckily there is now a standard called <aclass="reference external"href="https://en.wikipedia.org/wiki/Cross-origin_resource_sharing">CORS</a> (Cross-origin resource sharing), which enables exactly that.
Modern browsers support CORS, but there are problems with Internet Explorer <
10.</p>
<p>IE 8 and 9 partially support CORS via a proprietary implementation called
XDomainRequest. There is a <aclass="reference external"href="https://gist.github.com/1095825/6b4517276f26b66b01fa97b0a78c01275fdc6ff2">Strophe.js plugin</a> which you can use to enable
support for XDomainRequest when it is present.</p>
<p>In IE < 8, there is no support for CORS.</p>

<p>First, find out which object is referred to by <ttclass="docutils literal"><spanclass="pre">Object</span><spanclass="pre">[object</span><spanclass="pre">Object]</span></tt>.</p>
<p>It will probably be the jQuery object <ttclass="docutils literal"><spanclass="pre">$</span></tt> or perhaps the underscore.js object <ttclass="docutils literal"><spanclass="pre">_</span></tt>.</p>
<p>For the purpose of demonstration, I’m going to assume its <ttclass="docutils literal"><spanclass="pre">$</span></tt>, but the same
rules apply if its something else.</p>
<p>The bundled and minified default build of converse.js, <ttclass="docutils literal"><spanclass="pre">converse.min.js</span></tt>
includes within it all of converse.js’s dependencies, which include for example <em>jQuery</em>.</p>
<p>If you are having conflicts where attributes or methods aren’t available
on the jQuery object, you are probably loading <ttclass="docutils literal"><spanclass="pre">converse.min.js</span></tt> (which
includes jQuery) as well as your own jQuery version separately.</p>
<p>What then happens is that there are two <ttclass="docutils literal"><spanclass="pre">$</span></tt> objects (one from
converse.js and one from the jQuery version you included manually)
and only one of them has been extended to have the methods or attributes you require.</p>
<p>Which jQuery object you get depends on the order in which you load the libraries.</p>
<p>There are multiple ways to solve this issue.</p>
<p>Firstly, make sure whether you really need to include a separate version of
jQuery. Chances are that you don’t. If you can remove the separate
version, your problem should be solved, as long as your libraries are loaded in
the right order.</p>
<p>Either case, whether you need to keep two versions or not, the solution depends
on whether you’ll use require.js to manage your libraries or whether you’ll
load them manually.</p>
