Javascript and Jqeury consecutive countdown

I found a countdown script

JS FIDDLE

how do I change hours, minutes, second and title with JSON object like this?

[{"id":"1","title":"countdown 1","hour":"0","minute":"0","second":"10"},{"id":"2","title":"countdown 2","hour":"0","minute":"0","second":"10"},{"id":"3","title":"countdown 3","hour":"0","minute":"0","second":"10"}]

and show it one by one consecutively then redirect when all countdown done?

already using foreach loop, but it broke the countdown.
this script is different than other countdown that use Date.
