I have the below code.

How do I retrieve the value of class snipcart-details after the "add to cart" button has been clicked ?.

I keep getting the value of the first product even if I click on the second or third product.
        <script>

			$(document).ready(function() {

			    $(".button").click(function() {
					alert("Value: " + $("#item_name").val());
			    });
			});
			

        </script>

you should have a unique ID on a page : https://www.w3.org/TR/WCAG-TECHS/H93.html
anyway here how to do it : https://jsfiddle.net/ypwezcar/2/

			$(document).ready(function() {
			    $(".button").click(function(evt) {
			               evt.preventDefault(); // this is to stop posting the form, remove it if needed
			                var $myForm = $(this).closest("form");
			                var $myItem = $("input[id='item_name']", $myForm);
					alert("Value: " + $myItem.val());
			    });
			});

Your problem is that you have multiple forms with elements with the same ID.

This is not legal - id's must be unique. When you do a select on ID number multiple are going to be found but because ID's must be unique it will take the the first one. Consider this code
<html>
<body>
<div id="fred">fred 1</div>
<div id="fred">fred 2</div>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(function() {
  $('#fred').each(function(i,e) {
    alert(e.innerHTML);
  });
});
</script>
</body>
</html>

Open in new window

This will alert "Fred 1"
Now consider this code
<html>
<body>
<div class="fred">fred 1</div>
<div class="fred">fred 2</div>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(function() {
  $('.fred').each(function(i,e) {
    alert(e.innerHTML);
  });
});
</script>
</body>
</html>

Open in new window

This will alert Fred 1 and then Fred 2 - because classes can be duplicated - when you select on a class you get all matching elements.

While the above solution will work it is essentially just putting a plaster over the problem.

Here is how I would do your page.
1. Change your id="" to name="" for each form - this can be done with a search and replace
search: input" id=" and replace with input" name="

2. Add this jQuery
<script>
$(function() {
  $('form').submit(function(e) {
    // Prevent default form submit
    e.preventDefault();
	// get all the data for the input controls on the clicked form
    var data = $(this).serialize();
	// show them in the console
    console.log(data);
  });
});
</script>
