How to Implement Mouse Wheel Event Handling in jQuery?

Implement Mouse Wheel Event Handling in jQuery

jQuery provides a way to capture the mouse wheel events, which differ from scroll events. This article delves into the method to achieve this functionality effectively.

Solution:

jQuery offers the mousewheel event listener to handle mouse wheel events. It takes a callback function as its argument, which is executed upon registering the event. Here's a practical example:

<code class="javascript">$(document).ready(function() {
    $('#foo').bind('mousewheel', function(e) {
        if (e.originalEvent.wheelDelta / 120 > 0) {
            console.log('Scrolling up!');
        } else {
            console.log('Scrolling down!');
        }
    });
});</code>

In this snippet:

• $('#foo') specifies the element where you want to capture the mouse wheel events.
• mousewheel is the event listener that triggers the callback function when the mouse wheel is used.
• The callback function checks the direction of the mouse wheel scrolling based on the wheelDelta property.
• Positive wheelDelta signifies scrolling up, while negative values represent scrolling down.
