I am learing event.target and event.currentTarget. I think i am clear with the difference between the two. But stuck in a situation where event.currentTarget value turns out to be null.
Following are the HTML and JS code snippets:
HTML code
<form id="form">
This is a form
</form>
JavaScript Code
form.addEventListener('click', func);
function func(event) {
console.log(event.target.tagName); //line1
console.log(event.currentTarget.tagName); //line2
setTimeout(()=> {
console.log(event.target.tagName); //line3
console.log(event.currentTarget.tagName); //line4
}, 0) ;
}
My doubt is that in line1 and line3 I got the value of event.target the same. But there is a difference in the value of event.currentTarget in line2 and line4.
The output in line3 is 'form', but in line4 it is:
Uncaught TypeError: Cannot read property 'tagName' of null.
That means currentTarget is null in line4.
Can you explain why value of currentTarget is null in line4 ?
