Event capturing is one of two ways to do event propagation in the HTML DOM. In event capturing, an event propagates from the outermost element to the target element.
Event capturing is a type of event propagation where the event is first captured by the outermost element, and then successively triggers on the descendants (children) of the target element in the same nesting hierarchy till it reaches the innermost target DOM element.
You need to pass true value for addEventListener method to trigger event handlers in event capturing phase.
const parent = document.querySelector(“div”);
const child = document.querySelector(“.child”);
parent.addEventListener(“click”,
function () {
console.log(“Parent”);
},
true
);
child.addEventListener(“click”, function () {
console.log(“Child”);
});
// Parent
// Child
