JavaScript Create list from each create list from array,create list from string python,create

I am looping through elements using jQuery like this:

$(".myelement").each(function() {
  $element = $(this).closest(".panel").attr("id");
  console.log($element);
});

This is working correctly and I am seeing each of the elements it finds in my console log. I am now trying to get a string containing each element that looks like this:

#element1, #element2, #element3

What is the easiest way to do this? Does anybody have an example they can point me at?

Answer:1

You could use map() to build an array of the id then join() it, something like this:

var ids = $(".myelement").map(function() {
  return '#' + $(this).closest(".panel").prop("id");
}).get().join(', ');

console.log(ids);
Answer:2

You could use an array to store them by adding the # in every iteration, then after the loop end join them using join() method like :

var ids = [];

$(".myelement").each(function() {
  ids.push('#' + $(this).closest(".panel").attr("id"));
});

console.log(ids.join(', '));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="element1" class="panel">
  <span class="myelement">My element 1</span>
</div>
<div id="element2" class="panel">
  <span class="myelement">My element 2</span>
</div>
<div id="element3" class="panel">
  <span class="myelement">My element 3</span>
</div>
