A very good js countdown! Page real-time countdown, accurate to the second, and the day countdown principle. Js countdown is generally used in shopping mall website group purchase, sale, a lot of places are available to! I hope I can help you!

The effect is as follows:
< img SRC = "border = 0 / / files.jb51.net/file_images/article/201402/201402101105031.gif? 201411011526 ">
