You need to enable “Show whitespace characters” and the like.

See also <http://devtoolsecrets.com/> (referred to by the FAQ).

/Essato/.  With a for-in statement you only get the *enumerable* properties, 
and you cannot convert all property values to string.  In theory, ES 5’s 
Object.getOwnPropertyNames(…) gives you the names of all own property names, 
regardless whether the property is enumerable; but I have observed that it 
does not work that well with host objects – the array may be empty, 
unexpectedly.  However, the two approaches can be combined for a more 
complete picture.  (I wonder how they are doing it in the DOM Inspector; 
probably it is just a matter of UTSL.)

Undeclared identifier.  (You *really* want to use strict mode, and JSHint.)

  onclick="console.log(this)"
