    The easiest way to go about doing this, is to use jQuery.

    First, include jQuery in your <head></head> section:

    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>

    Then add in the following Javascript:

    $(document).ready(function() {
  $('input.foo').blur(function(){
    $.ajax('myScript.php');
  });
});

    This will setup the input (who’s class is foo) to use ajax to run myScript.php whenever someone clicks out of it, which in development terms is called blurring.
