title: Issues Stringifying a multidimensional array with json.js
body: <p>I have problems with <code>.stringify()</code>, but I think my JavaScript array must be wrong, here's my code:</p>
  
  <pre><code>var questions = new Array();
  
  $('#Valid').hover(function(){
      for (i=0;i &lt; $('.Questions').length;i++){
          questions[i]=new Array();
          questions[i]['numero']=$('.Numero:eq('+i+')').html();
          questions[i]['question']=$('.ItemInput:eq('+i+')').val();
          questions[i]['variable']=$('.VarName:eq('+i+')').val();
      }
  
      var stringJSON=JSON.stringify(questions)
      alert (stringJSON)
  })
  </code></pre>
  
  <p>The stringJSON var returns :</p>
  
  <pre><code>[[]]
  </code></pre>
  
  <p>What am I doing wrong?</p>
