Generate HTML List From JavaScript Array

Generate an HTML ul/li list based on the contents of a JavaScript array.

By modifying the makeList() function to accept parameters and target elements, you can pass different arrays and generate different lists inside different containers.

This vanilla JavaScript function has zero dependencies and works in all browsers.

function makeList() {
    // Establish the array which acts as a data source for the list
    var listData = [
        'Blue',
        'Red',
        'White',
        'Green',
        'Black',
        'Orange'
    ];

    // Make a container element for the list
    var listContainer = document.createElement("div");

    // Add it to the page
    document.getElementsByTagName("body")[0].appendChild(listContainer);

    // Make the list
    var listElement = document.createElement("ul");

    // Add it to the page
    listContainer.appendChild(listElement);

    // Set up a loop that goes through the items in listItems one at a time
    var numberOfListItems = listData.length;

    for (var i = 0; i < numberOfListItems; ++i) {
        // create an item for each one
        var listItem = document.createElement("li");

        // Add the item text
        listItem.innerHTML = listData[i];

        // Add listItem to the listElement
        listElement.appendChild(listItem);
    }
}

// Usage
makeList();
