How to use addEventListener with hover in JavaScript

If you want to perform an action when a user hovers over an HTML element, you can use the addEventListener method with the hover event in JavaScript.

To use addEventListener, you first need to select the HTML element you want to add the event to. You can do that using document.querySelector or similar methods. Once you have the element, you can add the event listener like this:


const myElement = document.querySelector('#myElement');

myElement.addEventListener('mouseenter', (event) => {
  // Do something when the mouse enters the element
});

myElement.addEventListener('mouseleave', (event) => {
  // Do something when the mouse leaves the element
});

In the example above, we select an element with the ID myElement and add two event listeners to it: mouseenter and mouseleave. The first one will trigger when the mouse enters the element, and the second one will trigger when the mouse leaves the element.

You can replace mouseenter and mouseleave with mouseover and mouseout, respectively, if you want the event listener to trigger when the mouse moves over the element, instead of just entering or leaving it.

If you prefer, you can also use the shorthand method of adding event listeners:


const myElement = document.querySelector('#myElement');

myElement.onmouseenter = (event) => {
  // Do something when the mouse enters the element
};

myElement.onmouseleave = (event) => {
  // Do something when the mouse leaves the element
};

This achieves the same result as using addEventListener, but some developers prefer this syntax because it's shorter.
