I am trying this code to detect if the mouse direction is going up or down:
<html>
<head></head>
<body>
<div style="width: 500px; height: 500px; background: red;"></div>
</body>
</html>
var mY = 0;
$('body').mousemove(function(e) {
mY = e.pageY;
if (e.pageY < mY) {
console.log('From Bottom');
return;
} else {
console.log('From Top');
}
});
However this code doesn't work was i expect. Console log always show "from top"
Any idea ?
