title: Array length in Javascript chrome error
body: <p>I have a very strange problem with js console in chrome,
  if i go in chrome console and write :</p>
  
  <pre><code>var numero = new Array(["/php/.svn/tmp", "/php/.svn/props"]);
  </code></pre>
  
  <p>return me "undefined" so i think numero is an array with 2 elements, but if i write:</p>
  
  <pre><code>numero
  </code></pre>
  
  <p>returns:</p>
  
  <pre><code>[Array[2]]
  </code></pre>
  
  <p>after </p>
  
  <pre><code>numero.length
  </code></pre>
  
  <p>and return 1 ..... why? don't return 2 ???
  where am I doing wrong?
  can i give a method that returns 2? 
  thanks in advance</p>
  
  <p>EDIT:
  I will explain my problem.
  I have a function that return this when i selected 2 items :</p>
  
  <pre><code>myFolders.getSelected()
  ["/php/.svn", "/php/upload.php"]
  </code></pre>
  
  <p>and this when selected one items:</p>
  
  <pre><code>myFolders.getSelected()
  "/php/upload.php"
  </code></pre>
  
  <p>as u note the second one isn't an array.</p>
  
  <p>now i use this method to activate on change selected item an calculate a global variable:</p>
  
  <pre><code>function calcoloNumeroElementi(){
      var numero = new Array(myFolders.getSelected());
      numeroElementiSelezionati = numero[0].length;
  }
  </code></pre>
  
  <p>but returns always 1 or the number of characters when i selected only one items.</p>
