尝试一下：
<button type="button">Click Me</button><p></p><script type="text/javascript"> $(document).ready(function(){ $("button").click(function(){ $.ajax({ type: 'POST', url: 'script.php', success: function(data) { alert(data); $("p").text(data); } }); });});</script>在script.php中
<?php echo "You win"; ?>
