jquery how to fire the same event every 5 seconds

问题

I've built a simple carousel with left and right scroll. Now I want to scroll automatically every 5 seconds. Here's my code:

function carousel(){
        $j('#carousel_ul li:first').before($j('#carousel_ul li:last'));

        $j('#right_scroll img').click(function(){

            var item_width = $j('#carousel_ul li').outerWidth() + 10;

            var left_indent = parseInt($j('#carousel_ul').css('left')) - item_width;

            $j('#carousel_ul:not(:animated)').animate({'left' : left_indent},800, 'easeOutExpo',function(){

                $j('#carousel_ul li:last').after($j('#carousel_ul li:first'));

                $j('#carousel_ul').css({'left' : '-750px'});
            });
        });

        $j('#left_scroll img').click(function(){

            var item_width = $j('#carousel_ul li').outerWidth() + 10;

            var left_indent = parseInt($j('#carousel_ul').css('left')) + item_width;

            $j('#carousel_ul:not(:animated)').animate({'left' : left_indent},800, 'easeOutExpo',function(){

            $j('#carousel_ul li:first').before($j('#carousel_ul li:last'));

            $j('#carousel_ul').css({'left' : '-750px'});
            });

        });
}

How do I achieve that? Thanks in advance :)

回答1:

You can use setInterval. Look:

window.setInterval(event, 5000);

And function event would be

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

EDIT:

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

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

回答2:

var i = setInterval(carousel, 5000)

And to stop it later:

clearInterval(i);
