如何添加下载链接php或javascript？

Question

我添加

"sources": <|php echo $file?>

结果

"sources":[{"type": "video/mp4", "label": "HD", "file": "https://video-12345.mp4"}]         }],

我想添加下载按钮

function() {
    window.location.href = " <|php echo $file?>";

结果

function() {
    window.location.href = [{"type": "video/mp4", "label": "HD", "file": "https://video-12345.mp4"}]            }],

所以我只想要视频链接？ 结果就像这样...

function() {
    window.location.href = "https://video-12345.mp4";

所以我想点击一下

进行下载

Answer 1

如果＆lt; | php echo $ file？＆gt;产生一个值数组，然后......

var data = [{"type": "video/mp4", "label": "HD", "file": "https://video-12345.mp4"}]; // output of <|php echo $file?>

function myFunction() {
    window.location.href = data[0]['file']; // first item in data array, file property value
}
