title: How to get current value of input element node
body: <p>I've been trying to make a browser extension that checks for if a certain string is present on a web page. It's able to find text in regular text nodes, but I'm trying to expand it to include inputs as well. I have the input node in hand, but using the <code>node.value</code> I am only able to get the initial value of the input. How would I go about getting the current value of an unsubmitted input?</p>
  <p>This is the documentation I've been reading</p>
