I get an undefine error in iframe

I have an iframe below:

<iframe class='upload_target' name='upload_target' src='#' style='width:0;height:0;border:0px;solid;#fff;'></iframe>

I am trying to stop a command below but I keep getting an undefined error: 

$('.upload_target').contentwindow is undefined

How can I fix this undefined error?

Below is code:

   $(".uploadbutton").click(function() {
          $(".upload_target").contentWindow.stop(); //for anything but IE
          $(".upload_target").contentWindow.document.execCommand("Stop"); // for IE
  return stopImageUpload();

});

You get undefined because contentWindow is native Javascript and you're using it on a jQuery collection, which doesn't have contentWindow as a value. You have to get the original DOM object first. Do this instead:

$('.upload_target').get(0).contentWindow
