You could either use an inline <script> tag to immediately execute
JavaScript or you simply attach an event listener:

<script type="text/javscript">
  window.addEventListener('load', function() {
    /* do something onload */
  }, false);
</script>

No, in this case use XHR.get:

<script type="text/javscript">
  XHR.get('/some/url', { random: 'post', data: 'foo' },
          function(x, data) {
            /* do something with x.responseText or data if the reply is
             * valid JSON */
          }
  );
</script>

HTH,
Jow
