The id for all the elements are same in your code. Use document.querySelectorAll to get the list of elements.

 function getdata() { var num = document.getElementById("number").value; console.log(num); $(document).ready(function() { for (var i = 0; i < num; i++) { $('<div><select id="select-meal-type' + i + '"><option value="TYPE A">TYPE A</option><option value="TYPE B">TYPE B</option><option value="TYPE C">TYPE C</option></select><br></div>').appendTo('#container'); } }); } function getValues() { var nodeList = document.querySelectorAll("[id^=select-meal-type]") var values = Array.from(nodeList).map(val => val.value) console.log(values); }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <br><br> type a number<input type="text" id="number"> <br><br> <div id="container"></div> <button onclick="getdata()">GET DATA</button> <button onclick="getValues()">GET VALUES</button>
