Currently, I am facing a scenario where I have a button and I need an event to continuously trigger while the button is being hovered. Unfortunately, using the mouseover method only causes the event to fire once when the cursor initially moves over the button from outside.
btn.addEventListener("mouseover", function(){
console.log("Hello");
});
Ideally, I would like the console log to display continuously as long as the cursor remains hovering over the button.
To achieve this effect, you can utilize the mouseover and mouseout events along with a setInterval. Simply start an interval when the mouse enters an element and clear it when it exits.
let customInterval;
button.addEventListener("mouseover", function(){
customInterval = setInterval(function() {
console.log("Greetings!");
}, 100);
});
button.addEventListener("mouseout", function(){
clearInterval(customInterval);
});
Could you please verify if the mousemove event is functioning correctly on your end?
let interval = null;
btn.addEventListener("mousemove", function(){
console.log("Hello");
});
btn.addEventListener('mouseenter', function(){
interval= setInterval(()=>console.log('Hello'), 100)
})
btn.addEventListener('mouseout', function(){
clearInterval(interval)
})#btn{
width: 300px;
height: 60px;
border-radius: 8px;
} <button id="btn">
hover me
</button>If you're looking to determine which elements are currently being hovered over, there are a few methods you can try:
While it may seem like an unusual scenario (since you can't hover over multiple adjacent elements simultaneously), it's still a useful exercise.
function addEventListeners(button) {
button.addEventListener("mouseover", () => button.dataset.hovered = "1");
button.addEventListener("mouseout", () => button.dataset.hovered = "0");
}
function reportHovers(elements) {
const hoveredIds = elements.filter(el => el.dataset.hovered === "1").map(el => el.id);
document.getElementById("out").value = `${Math.floor(new Date() / 1000)}\n${JSON.stringify(hoveredIds)}`;
}
var buttons = Array.from(document.querySelectorAll("button"));
buttons.forEach(button => addEventListeners(button));
setInterval(() => reportHovers(buttons), 100);<button id="b1">Button 1</button>
<button id="b2">Button 2</button>
<button id="b3">Button 3</button>
