title: jQuery detect select in radio button
body: <p>I want to build form with radio buttons, where i need to detect if all radio has bee selected.</p>
  
  <p>It's quite easy function .change. In my situation:</p>
  
  <pre><code>    $('input:radio').change(function() {
      alert($('[name|="pyt10"]:checked').val() + " / " + $('[name|="pyt11"]:checked').val() + " / "+ 
  })
  </code></pre>
  
  <p>But here is small issue - i have 3 groups of radios. When i select first radio, alert shows me, that all fields are udefined, after second select first radio has value, but second is still undefined, and so on.</p>
  
  <p>It means, that my alert shows radio value before change, not after.</p>
  
  <p>What should i do to write radio value after select ?</p>
