Component closest method

[Baghunts]

For finding some closest element by selector, we can use the closest method, which in your turn, uses jQuery's closest method.

jQuery's closest method also returns the element self too. I think it will be great to use the parents method instead closest, for skipping the element from the search

@Baghunts Hello,

Thanks for the highlight.

Will this change improve performance to traverse the DOM?

[Bagunc]

Yes, because it will skip the element itself from the search. But here the problem is a more logical case than speed.

For example, we have a structure

row#mainRow > col > row#innerRow

If I will use the closestType("row") in #innerRow component it will return itself because the jQuery .closest method starts from elements.
I suggest using jQuery .parent, for excluding the element itself in the search.

closest seems to be the fastest 🤔

Well, honestly I think it's better to keep it as it is even because that might introduce unexpected behavior due to how it works right now.
If you need to skip the component itself just select the parent and then do the closest call (eg. cmp.parent().closest('...'))
