How to detect scroll direction
I managed to figure it out in the end, so if anyone is looking for the answer:
//Firefox
$('#elem').bind('DOMMouseScroll', function(e){
if(e.originalEvent.detail > 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
//IE, Opera, Safari
$('#elem').bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta < 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
Following example will listen to MOUSE scroll only, no touch nor trackpad scrolls.
It uses jQuery.on() (As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document).
$('#elem').on( 'DOMMouseScroll mousewheel', function ( event ) {
if( event.originalEvent.detail > 0 || event.originalEvent.wheelDelta < 0 ) { //alternative options for wheelData: wheelDeltaX & wheelDeltaY
//scroll down
console.log('Down');
} else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
Works on all browsers.
