jQuery scroll() detect when user stops scrolling

Question

Ok with this..

$(window).scroll(function()
{
    $(\'.slides_layover\').removeClass(\'showing_layover\');
    $(\'#slides_effect\').show();
});

Answer 1

Using jQuery throttle / debounce

jQuery debounce is a nice one for problems like this. jsFidlle

$(window).scroll($.debounce( 250, true, function(){
    $('#scrollMsg').html('SCROLLING!');
}));
$(window).scroll($.debounce( 250, function(){
    $('#scrollMsg').html('DONE!');
}));

The second parameter is the "at_begin" flag. Here I've shown how to execute code both at "scroll start" and "scroll finish".

Using Lodash

As suggested by Barry P, jsFiddle, underscore or lodash also have a debounce, each with slightly different apis.

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('SCROLLING!');
}, 150, { 'leading': true, 'trailing': false }));

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('STOPPED!');
}, 150));
