How to check for the presence of an element?
<p>I'm using the <code>.length</code> method in a conditional statement that polls the page for the presence of an externally-loaded object (I can't style it with jQuery until it exists):</p>

<blockquote>
<pre><code>function hackyFunction() {
  if($('#someObject').length&lt;1)
  { setTimeout(hackyFunction,50) }
  else
  { $('#someObject').someMethod() }}
</code></pre>
</blockquote>

<p>Is <code>length</code> the best way to do this?</p>
