Using value from column for right clickable menu in table

I hope someone can help. I have a 13 column table of members details, using javascript I have a right clickable menu displayable on each row.
In one column one, which is hidden, is the record ID number of each member. Is it possible to get the value from this column and use it to show the member details. Ie if the id is 12345 then store it in variable called id-column-one. I have included my code below.

Thanks Rob

Your actions here case "View": window.open("https://url/memb-details-all/"id-column-one); break; case "Renew": alert("Renew"); break; case "Amend": alert("Amend"); break; } // Hide it AFTER the action was triggered $(".custom-menu").hide(100); }); </script>
