Retrieving element with no name or id
<p>I am trying to write some code to accomplish something very simple.  I have never worked with a PayPal button before, which is causing some difficulty.  </p>

<p>I have been able to simulate a button click before, using document.getElementById or document.getElementsByName(), however, the form I am trying to submit above does not have a name, or an id, so I do not know how to refer to it in my code. </p>

<p>I am trying to write a short chrome extension using Javascript that will find the paypal form/button on the page (that I do not own or have control over), and submit it without me having to click it.  Any guidance/links would be much appreciated.  </p>
