Javascript/jQuery "Gotchas"
<p>What are some of the common Javascript and/or jQuery "gotchas" that you have seen or been tripped up by?</p>

<p>As an example, it was pointed out to me this morning that you have to be careful with the radix when doing <code>parseInt()</code>, because if your string starts with a 0, the radix will default to 8.</p>
