How to get particular index by click event in js

Question

I am confused to get index by click event
<ul class="list">
<li>a</li>
<li>b</li>
</ul>
If we get document.getElementsByClassName("list");
It will return an array so I want to get a particular index of an element like first tag li tag index is 0 2nd li tag index is 1

Answer 2

What does index mean here? did you mean to get the text in one <li> element one at a time?
Which element should trigger this on click event?

Answer 3

document.getElementsByClassName("list"); will return a collection of all element references having "list" as class name, or undefined in case no element was found to match the class name filter.
I see in the code <ul class="list">. So document.getElementsByClassName("list") will (on success) return a collection of <ul> element references, rather than a collection of <li> elements.
Anyways, which element is to be clicked to trigger the behaviour? a <button>? or something else?

Answer 4

Yes

Answer 5

When we click on any li tag it should return their appropriate index
