title: jQuery Auto Calculation based on Field
body: <p>I have this bit of code:</p>
  
  <pre><code>&lt;label&gt;Number of Shares:&lt;/label&gt;&lt;input name="shares" id="shares" type="text" /&gt;
  
  Total Value: &amp;euro; 0.00
  </code></pre>
  
  <p>All I need to do is to auto calculate while you type the total value. For example if someone enters 100 in the field, I need to multply it with 1.50 so 0.00 below the field will be replaced with 150.00.</p>
  
  <p>Can someone tell me how can I do this with jQuery?</p>
