Make Ajax call after page load

1000 is in milliseconds -- ten seconds would be 10000. Also, you're looking for $(document).ready:

$(document).ready(function(){
    setTimeout(function(){
       loadajax();
     },10000); // milliseconds
});

http://api.jquery.com/ready

So many answers, all slightly different, but the shortest recommended syntax to run the function 10 seconds after DOM ready, while still retaining best practices, would be:

$(function(){
    setTimeout(loadajax,10000);
});

As Blazemonger mentions below, you could simply put setTimeout(loadajax,10000); at the end of the document, however that is not as flexible to change. jQuery DOM load code should always be in a jQuery DOM load event (i.e. $(function(){...});)
