下载.php
<?php
//file path in server
$path = $_POST["folder_name"] . '/' . $file;
// check if file exist in server
if (file_exists($path)) {
header("Cache-Control: public");
header('Content-Description: File Transfer');
header('Content-Type: application/x-javascript');
header('Content-Disposition: attachment; filename="' . basename($path) . '"');
header('Content-Length: ' . filesize($path));
// Clear output buffer
flush();

exit();
} else {
echo "File not found.";
}
?>
现在的问题是，当我从服务器下载javascript文件时，它会下载文件，但其中没有任何内容。在服务器上，文件包含内容，因此从网站下载文件时一定有问题。我认为问题出在下载上.php但在我看来语法是正确的。这也可能是索引.php和行动.php中remove_file功能的问题。参见 $(document(.on('click'， '.remove_file'， function(( in index.php
我会说你需要html。我不知道你是否可以为此使用 PHP。如果你真的需要使用 PHP：
<?php
echo "<a href='file.js' download>Click Here to Download</a>";
?>
从本质上讲，这样做是创建一个链接，用户在其中单击以下载文件。
