Detecting mousewheel on the x-axis (left and right) with Javascript
internet-explorer-10, internet-explorer-9, javascript, mousewheel, scroll
Solution
The `DOMMouseWheel` event in Firefox has an `axis` property.
The `mousewheel` event in Chrome has `wheelDeltaX` and `wheelDeltaY`.
Sadly, I cannot find any equivalent propery for IE events (testing on IE9).
Problem
I know it's possible to detect up and down e.g. ``` function handle(delta) { if (delta < 0) { alert('down'); } else { alert('up'); } } function wheel(event){ var delta = 0; if (!event) event = window.event; if (event.wheelDelta) { delta = event.wheelDelta/120; } else if (event.detail) { delta = -event.detail/3; } if (delta) handle(delta); if (event.preventDefault) event.preventDefault(); event.returnValue = false; } /* Initialization code. */ if (window.addEventListener) window.addEventListener('DOMMouseScroll', wheel, false); window.onmousewheel = document.onmousewheel = wheel; ``` But is there a way to detect if a user's mouse went left or right with the mousewheel?
