问题:

i have some problems with my script. So, i want to detect end of my scrolling action. I have my alert when i'm scrolling but not if i'm ending it. Can you help me? This is my code:

var animatable = $('body, html');
var animating = false;
animatable.animate( {scrollTop: $('#foo').offset()})

$(window).scroll(function(e) { 
       if(!animating){
           animatable.stop(false, true); 
           alert('stop scrolling');
       }
       animating = false;
});

and some fiddle: http://jsfiddle.net/yhnKR/

回答1:

is this what you're trying to achieve:

$('body').animate( {scrollTop: $('#foo').offset().top},1000,function(){
 alert('stop scrolling');   
});

You don't have to watch the scroll event if you animate the scroll with jquery.

Ok, if you want to detect when the user stopped scrolling, you'll have to use a timeout to check if the user stopped. Otherwise you'll get the event for each scroll step. Like this:

var delay = 1000;
var timeout = null;
$(window).bind('scroll',function(){
    clearTimeout(timeout);
    timeout = setTimeout(function(){
        alert('scrolling stopped');
    },delay);
});
