您熟悉AJAX吗？如果您已经知道，请原谅我，但是如果您不知道，请原谅我：
Ajax将数据发布到外部php文件，该文件处理接收到的数据，并发送回答案。看起来像这样：
文件1：
<html> <head> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('#Sel').change(function() { var opt = $(this).val(); var someelse = 'Hello'; var more_stuff = 'Goodbye'; $.ajax({ type: "POST", url: "receiving_file.php", data: 'selected_opt=' + opt + '&something_else=' +someelse+'&more_stuff='+more_stuff, success:function(data){ alert('This was sent back: ' + data); } }); }); }); </script> </head><body><select id = "Sel"> <option value ="Song1">default value</option> <option value ="Song2">Break on through</option> <option value ="Song3">Time</option> <option value ="Song4">Money</option> <option value="Song5">Saucerful of Secrets</option></select>文件＃2：receiving_file.php
<?php $recd = $_POST['selected_opt']; echo 'You chose: ' . $recd;
