Is there a SelectedIndex for an HTML5 DataList?

Question

You can pick the current option of any select element:

mySelect.options[mySelect.selectedIndex]

Can I do the same wit

No, the datalist element is for providing autocomplete to inputs. It is a source of data, is hidden from the user, and multiple inputs may link to it. Therefore it doesn't make sense to have a selectedIndex.

Instead, you should simply check the .value of the input:

var datalist = document.getElementById ("datalist");
var input = document.getElementById ("input");

input.addEventListener ("keyup", function (event) {
    if (event.which === 13) {
        alert(input.value);
    }
}, false);
