Detecting mousewheel on the x-axis (left and right) with Javascript

Question

I know it\'s possible to detect up and down e.g.

    function handle(delta) {
    if (delta < 0) {
        alert(\'down\');
} else {
    alert(\'up\');
           


        

Answer 1

I believe you can find the 'horizontal' or x-axis data from

event.originalEvent.wheelDeltaX

You should debug the code, and see what properties the event object has at runtime. This should confirm or deny if that property exists. From there, it is just a matter of detecting if the value differs.
