CODE HIỂN THỊ THỜI GIAN VIDEO TRÊN YOUTUBE

[tintuc]
Trong hướng dẫn này tôi sẽ hướng dẫn bạn cách làm để có thể lấy được thời gian của một Video đó thông qua ID của Video.

Đây là script để lấy thời gian dưới dạng số giây thông qua ID của Video là : OnyXzPuF2tQ

<script type="text/javascript">
var erhayid = "OnyXzPuF2tQ";
function youtubeFeedCallback(json){
document.write(json["data"]["duration"]);
}
var timer = document.write("<script src=\"http://gdata.youtube.com/feeds/api/videos/"+erhayid+"?v=2&alt=jsonc&callback=youtubeFeedCallback&prettyprint=true\"><\/script>");
</script>

Trong đoạn Code trên erhayid là chính là ID của Video của mỗi Youtube. Với đoạn code này sẽ chỉ giúp bạn lấy được thời gian dưới dạng second(giây) của Video đó. Để chuyển sang dạng phút:giây bạn dùng. Bạn có thể save với đuôi HTML để chạy thử.

<script type="text/javascript">
//This code by Erhay.com
function youtubeFeedCallback(json){
var sec1 = (json["data"]["duration"]);
var hour = Math.floor(sec1 / 3600);
var minutes = Math.floor((sec1 - (hour * 3600)) / 60);
var sec = ( json["data"]["duration"] % 60);
document.write(minutes + " : "+sec);
}
var erhayid = "OnyXzPuF2tQ";
var stimer = "<script src=\"http://gdata.youtube.com/feeds/api/videos/"+erhayid+"?v=2&alt=jsonc&callback=youtubeFeedCallback&prettyprint=true\"><\/script>";
document.write(''+stimer+'');
</script>

Ok. Giờ chúng ta sẽ áp dụng vào Json để lấy ra Video và thời gian như sau. Áp dụng vào Blogspot của bạn. Style dạng bài viết mới nhất như hình :

- Tạo button comment dạng lightbox blogspot.

- Cách thêm font vào Website.

- Ẩn hiện thẻ div với button.

- Đưa form liên hệ vào lightbox với fancybox
