Welcome to Stack Overflow. *"please do check my codes for some problem"* - Please [edit] your question to describe more clearly the desired behaviour and the actual behaviour. When you run your code what happens? (Nothing? Something, but the wrong thing? Are there errors in the browser's dev console?) — nnnnnn, Jul 23 '16 at 23:49
sorry about that. what i really want to express is that, when animate() done executing, after 1000 of ms the reverse() well take place. something like this animate() wait 1 sec and then reverse() and repeat. — Ryan Khoo, Jul 24 '16 at 00:45

Use slideShow(); at the end of your javascript code.

Anyway, I recommend you to use http://unslider.com/ as a jQuery plugin.

He calls the function in the onload attribute of body so if he does call it at the end of his js, he would have duplicated the call. – Cameron Jul 24 '16 at 00:08
My bad. I didn't fully understand what he is trying to do. – Paulius K. Jul 24 '16 at 00:10
some what looping? when animate() done executing , wait for 1 sec then reverse() will do . and repeat. – Ryan Khoo Jul 24 '16 at 00:52
Ya, my bad dude, I didn't understand what you were trying to do. You can do that with setTimeout function, source: http://stackoverflow.com/questions/1183872/put-a-delay-in-javascript and then use the reverse funtion. – Paulius K. Jul 24 '16 at 15:26

For the setInterval function in slideShow(), put either

setInterval('animate()', 1000);

Or

setInterval(animate, 1000);
