您可以使用setInterval.看:

You can use setInterval. Look:

window.setInterval(event, 5000);

函数事件应该是

function event() {
 $j("#right_scroll img").click();
}

谢谢@cris！ setTimeout仅调用一次.我更改为setInterval.

Tks @cris! setTimeout calls only one time. I changed to setInterval.

Tks @熊！现在，我将一个函数传递给setInterval.

Tks @bears! Now I pass a function to setInterval.
