Steps for Filling a List Box (combo box) with Data from a Multi-Dimensional Array

As a student learning JavaScript, I have an assignment due tonight and am facing challenges with populating a List Box (combo box) from a Multi-Dimensional Array.

After working on the code multiple times, I managed to create a multi-dimensional array that functions correctly (I tested it by sending the results to an alert box).

var concertArray = [
        ["Billy Joel", "99", "equal.png"],
        ["Bryan Adams", "89", "higher.png"],
        ["Brian Adams", "25", "lower.png"]
];

However, I am struggling to figure out how to populate this array into a select list box (combo box).

I would greatly appreciate any assistance provided. Thank you!

Try using the following code snippet.

<html>

    <head>
     <script type="text/javascript">
        var artistsArray = [
            ["Taylor Swift", "90", "equal.png"],
            ["Ed Sheeran", "85", "higher.png"],
            ["Adele", "70", "lower.png"]
            ];

            function displayArtists(){

                for(i=0;i<artistsArray.length;i++){
                    var selectElement = document.getElementById("artistSelection");
                    selectElement.options[selectElement.options.length] = new Option(artistsArray[i][0], artistsArray[i][1]);
                }

            }
        </script>
        </head>

    <body onload="displayArtists();">
        <select id="artistSelection">
        </select>
    </body>     
</html>

To populate a combo box with data from an array, first extract the desired data from the array and then utilize jQuery append to insert them into the select tag.

<select id="dropdown">
</select>

Loop through the array and save the data to be added in a variable, for example, var info, and proceed as follows:

$('#dropdown').append('<option value="'+info+'">'+info+'</option');
