            alert("working");
        $.post('download.php',{pdf:'Intro.pdf'},function(data){if(data=="y"){alert("Downloaded");}});

Try this: 尝试这个：

<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>
    </head>
    <body>
        <a href="download.php?pdf=Intro.pdf">download</a>
    </body>
</html>

<?php
if(isset($_GET['pdf'])){
    $bbpdf = $_GET['pdf'];

    header("Pragma: public"); // required
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private", false); // required for certain browsers
    header("Content-Type: application/pdf");
    header("Content-Disposition: attachment; filename=\"" . basename($bbpdf));
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: " . filesize($bbpdf));
    ob_clean();
    flush();
    readfile($bbpdf);
}

Note: Don't use AJAX. 注意：不要使用AJAX。 There is no cross-browser way to force the browser to show a save-as dialog in JavaScript for some arbitrary blob of data received from the server via AJAX. 没有跨浏览器方式强制浏览器在JavaScript中显示一个存储对话框，用于通过AJAX从服务器接收的任意blob数据。
