How can I handle loop running twice in javascript?

Question

I am working on a project in which I am using dragster library.I am trying to build a cards game . I stuck when I am trying to get values of card using dragster function.It runs loop twice which I dont want(first it runs 13 times then it run to what I want) .I want only that loop that runs last as it contain all elements which I need.First one run 13 times always.Its running like this:

0
1
.
.
upto 12
then it again run
0 to 11(this loop I want).

How can I ignore above loop. My code:

$('.test .block').find('div.Hearts').each(function(i,val){
                 let h = $(val).find('p#number').text();
                  console.log(h)

            })

You need to find out why it runs twice, rather than add more code to stop it doing that. — Reinstate Monica Cellio

you say the second loop has what you want ... so what does the first loop (0 - 12) "have"? and this code snippet suggests you have multiple <p> elements with the same id - which is invalid HTML for a start - also, there are 13 hearts in a deck of cards, just sayin' — Jaromanda X

I am using dragster package and using dragster function also which also on drag it runs loops and after dropping element it also run (this one which I want) — Andrew

This looks like an issue with understanding jQuery's

Each http://api.jquery.com/jquery.each/

Find https://api.jquery.com/find/

The issue most likely relates to you having multiple elements returned in the find which the each then runs on.

I would advise you either use more specific selectors - for debugging log out $(this) from inside the each to see which element it's targeting.

This is what I was thinking, there must be multiple elements returned by find() method.
