title: Is it possible to use external function (Chrome extension) in my JS file?
body: <p>When loading Chrome extension, I am able to use the (for example) <code>function x()</code> from the console. I'm trying to write script when the page <code>onload</code> it will execute <code>x()</code> function... read about <code>eval()</code>... didn't go well...
  is there any way to ask the console to execute <code>x()</code>?</p>
  
  <p>Maybe someone have any idea how to do that?</p>
  
  <p>Thanks!</p>
