JavaScript在新窗口打开链接后跳转到新窗口

<script>
    var mp3 = 'https://example.com/somefile.mp3';
    var newWindow = window.open(mp3, '_blank');
    newWindow.onload = function() {
        window.location.href = newWindow.location.href;
    };
</script>
<p>这段代码会在新窗口中打开 'https://example.com/somefile.mp3' 链接，并在新窗口加载完成后将当前窗口重定向到新窗口的URL。请将 'https://example.com/somefile.mp3' 替换为你要打开的链接。</p>
