How can I access the contents of a form submission via Javascript?
<p>I have server side caching running on a website, and need to trigger functionality based on the submission of a form.  How can I access the contents of a form submission via Javascript?  Usually I would access these with PHP via $_POST.</p>

<p>I can't get the values via PHP because the page that is being served after the form submission is the cached page, and no PHP will be executed.</p>

<p>I am using jQuery.</p>
