<h1 id="update">Update</h1>
<p>In fact this method works for old threads. But it fails to create new post threads. This is why I tried and be conquered by <a href="http://intensedebate.com">intensedebate</a>, as you can see in the bottom of this page.</p>
<p>Remark I didn’t have any comment on my blog when I switched. Therefore my lack of influence was a good thing :-).</p>
<hr />
<p>Before begining, I must state that I <strong>love</strong> Disqus.</p>
<p>I know there is a similar blog entry at <a href="http://trephine.org/t/index.php?title=Site_improvements_-_fighting_with_Disqus">Trephine.org</a>. Here I just add a straight and easy way to load disqus asynchronously using jQuery.</p>
<p>I also know there is a jQuery plugin to make just that. Unfortunately I had some issue with CSS.</p>
<p><em>Now let’s begin.</em></p>
<hr />
<h1 id="why">Why?</h1>
<p>Why should I want to load the disqus javascript asynchronously?</p>
<ul>
<li>Efficiency: I don’t want my page to wait the complete execution of disqus script to load.</li>
<li>More independance: when disqus is down, my page is blocked!</li>
</ul>
<hr />
<h1 id="how">How?</h1>
<p>I give a solution with jQuery, but I’m certain it will work with many other js library.</p>
<h3 id="javascript">Javascript</h3>
<p>replace:</p>
<div>
<div class="sourceCode" id="cb1"><pre class="sourceCode javascript"><code class="sourceCode javascript"><a class="sourceLine" id="cb1-1" title="1"><span class="op">&lt;</span>script type<span class="op">=</span><span class="st">&quot;text/javascript&quot;</span> src<span class="op">=</span><span class="st">&quot;http://disqus.com/forums/YOUR_DISQUS_ID/embed.js&quot;</span><span class="op">&gt;</span>&lt;/script<span class="op">&gt;</span></a></code></pre></div>
</div>
<p>by</p>
<div>
<div class="sourceCode" id="cb2"><pre class="sourceCode javascript"><code class="sourceCode javascript"><a class="sourceLine" id="cb2-1" title="1"><span class="va">window</span>.<span class="at">disqus_no_style</span><span class="op">=</span><span class="kw">true</span><span class="op">;</span></a>
<a class="sourceLine" id="cb2-2" title="2"><span class="at">$</span>(document).<span class="at">ready</span>(<span class="kw">function</span>()<span class="op">{</span></a>
<a class="sourceLine" id="cb2-3" title="3"> <span class="va">$</span>.<span class="at">getScript</span>(<span class="st">&quot;http://disqus.com/forums/YOUR_DISQUS_ID/embed.js&quot;</span>)<span class="op">;</span></a>
<a class="sourceLine" id="cb2-4" title="4"><span class="op">}</span>)<span class="op">;</span></a></code></pre></div>
</div>
<p>If you forget the <code>window.disqus_no_style=true;</code> then your page will be blank. Simply because without this option, the javascript use a <code>document.write</code> action after the document was closed, which cause a complete erasing of it.</p>
<h3 id="css">CSS</h3>
<p>But with this option you still need to provide a CSS. This is why you have to copy the css code from the <code>embed.js</code> file and rewrite it in a CSS file. You can <a href="../../../../Scratch/en/blog/11_Load_Disqus_Asynchronously/code/original_disqus.css">download the CSS</a> I obtained.</p>
<hr />
<p>Now it’s done. I believe all should be fine but I just finished the manip for my own site only 1 hour ago. Therefore there should be some error, tell me if it is the case.</p>
