title: radio button ID value
body: <p>I have a radio group where I need to do some math calculations based on the value of the radio selected, but I also need a way to know my identity value for the SQL record it represents. Normally I would have that stored in the "value" attribute of the radio button. </p>
  
  <p>What I tried to do here is have different ID's for the same class, and I am trying to figure out how to determine the ID assigned</p>
  
  <pre><code>&lt;input type="radio" class="price" name="price" value="20.00" checked="true" id="1" /&gt;
  &lt;input type="radio" class="price" name="price" value="385.00" id="2" /&gt;
  &lt;input type="radio" class="price" name="price" value="504.00" id="3" /&gt;
  
  $('.price').change(function() {
  calculate();
  });
  
  function calculate () {
      var q = $('input#quantity').val();
      var p = $("input[name=price]:checked").val();
      var tot = ((q*p)+parseInt(s));
      $('input#total').val(tot);
  };
  </code></pre>
  
  <p>So in the calculate() function, I get the value but how can I get the ID for the radio button checked? Maybe this is backwards and there is a better way to get my dollar value for the math calculation part and I am open to any suggestions.</p>
  
  <p>TIA - Dan</p>
