How to detect if an element has focus using JavaScript
To detect if the element has the focus in JavaScript, you can use the read-only property activeElement of the document object.
const elem = document.activeElement;
The activeElement returns the currently focused element in the document.
The following example demonstrates how you can use the activeElement property to check if the <input> element with class name .name has focus:
const elem = document.querySelector('.name');
if (elem === document.activeElement) {
console.log('Element has focus!');
} else {
console.log('Element is not focused.');
}
