[HTML 5] stopPropagation & stopImmediatePropagation
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | const app = document.getElementById( 'app' ); app.innerHTML = ` <h1>JavaScript DOM</h1> <div class = "one" > <div class = "two" > <button type= "button" class = "three" > Click Me </button> </div> </div> `; const one = document.querySelector( '.one' ); const two = document.querySelector( '.two' ); const three = document.querySelector( '.three' ); function handleClick( event ) { event .stopPropagation(); // event.stopImmediatePropagation(); console.log( event .target); } one.addEventListener( 'click' , handleClick); two.addEventListener( 'click' , handleClick); three.addEventListener( 'click' , handleClick); three.addEventListener( 'click' , event => console.log( event ), { capture: true }); |
When use 'stopPropagation', the code:
three.addEventListener('click', event => console.log(event), { capture: true });
will still running.
But when use 'stopImmediatePropagtion', that line of code will not run any more
