javascript - jquery load do not answer on call via load -

i have seen voting system on http://htmlinspiration.com/ (click in heard)

they use:

$(".vote").click(function() {     $(this).load($(this).attr('href'));     console.log("voted");     return false; }); 

with html:

<aside>     <a onclick="return false" class="vote" href="http://www.dasunddas/vote.php">10</a> </aside> 

i tried too. without success. php file is:

<?php header('content-type: text/html; charset=iso-8859-1'); echo "100"; ?> 

i not answer load. if call php-file direct answers 100.
