title: Age from Date of Birth using JQuery
body: <p>I need to calculate if someone is over 18 from their date of birth using JQuery.</p>
  
  <pre><code>var curr = new Date();
  curr.setFullYear(curr.getFullYear() - 18);
  
  var dob = Date.parse($(this).text());
  
  if((curr-dob)&lt;0)
  {
      $(this).text("Under 18");
  }
  else
  {
      $(this).text(" Over 18");
  }
  </code></pre>
  
  <p>There must be some easier functions to use to compare dates rather than using the setFullYear and getFullYear methods.</p>
  
  <p>Note: My actual reason for wanting to find a new method is length of the code. I have to fit this code into a database field that is limited to 250 chars. Changing the database is not something that can happen quickly or easily.</p>
