Creating a HTML5 datalist on the fly

Question

I\'m trying to create a datalist on they fly and attach it to an existing input element. But nothing happens (no dropdown arrow is shown) jQuery would be acceptable, too.

Answer 1

JS

    var optionList = ["Seattle", "Las Vegas", "New York", "Salt lake City"];

    function fillDataList() {

        var container = document.getElementById('my-text-box'),
        i = 0,
        len = optionList.length,
        dl = document.createElement('datalist');

        dl.id = 'dlCities';
        for (; i < len; i += 1) {
            var option = document.createElement('option');
            option.value = optionList[i];
            dl.appendChild(option);
        }
        container.appendChild(dl);
    }

fillDataList();
