Answer: Use the jQuery $.each() Function
You can use the jQuery $.each() function to easily populate a select box (dropdown list) using the values from a JavaScript object. The $.each() function can be used to iterate over any collection, whether it is an object or an array. Let's try out an example to see how it actually works:
Example
Try this code »<!DOCTYPE html>
<html lang="en">
<head>
<title>jQuery Add Options to a Select from a JS Object</title>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
// Sample JS object
var colors = { "1": "Red", "2": "Green", "3": "Blue" };
$(document).ready(function(){
var selectElem = $("#mySelect");
// Iterate over object and add options to select
$.each(colors, function(index, value){
$("<option/>", {
value: index,
text: value
}).appendTo(selectElem);
});
});
</script>
</head>
<body>
<label>Color:</label>
<select id="mySelect">
<option value="0">Select</option>
</select>
</body>
