I want to run a javascript function from the browser console,
I'm trying to do it in Chrome (windows 7) and my function is this:

function playVideo() {
    var popo = document.getElementsByTagName("object");
      for (var i=0; i<popo.length; i++) {
        popo[i].playVideo(); 
      }
  }

normally this function works fine when I fire it from a webpage

<button onclick="playVideo();">play</button>

or

<a href="javascript:playVideo();">play</a>

but if I paste it into the browser console, and I press Return,
it doesn't work and there is this error:
"undefined"

What i'm doing wrong?

After paste to console and pressing return you must call this function by name, in you case, after "undefined" write to consle "playVideo()" and press Return.
