Dart Polymer & dart:js: getElementById() returns only [object Object]

Question

When I execute this code:

<!DOCTYPE html>
  <html>
    <head>
      <script language="javascript">
        function foobar() {
           alert(document.getElementById("myPdf"));
        }
      </script>
    </head>
    <body>
      <object id="myPdf" type="application/pdf" data="file.pdf"></object>
      <input type="button" value="Click" onClick="return foobar();">
    </body>
  </html>

[object] HTMLObjectElement is alerted.

But doing the same thing with Dart Polymer in combination with dart:js, ie the object-element is added to the DOM via Dart Polymer and the javascript code is executed via context.callMethod("foobar") , only [object] Object is alerted. Why is this the case? How to get the more specific HTMLObjectElement in this case?

我自己找到了解决方案：对象具有属性“ impl”，其中存储了HTMLObjectElement。
