as like the above image, the countdown get starts to go for windows location page. here we are going to see the script what we need to make this redirection. it should need jquery min file and the below script.
the highlight link is the url, where you have to redirect.
this code comes in the body tag. eval makes the countdown.
within the id="sec" what you given, that will make countdown from that number. then you will redirect to the page of what you given in the window.location url.
