javascript - Retrieving the text of the selected <option> in <select> element

In the following:

<select id="test">
    <option value="1">Test One</option>
    <option value="2">Test Two</option>
</select>

How can I get the text of the selected option (i.e. "Test One" or "Test Two") using JavaScript

document.getElementsById('test').selectedValue returns 1 or 2, what property returns the text of the selected option?

function getSelectedText(elementId) {
    var elt = document.getElementById(elementId);

    if (elt.selectedIndex == -1)
        return null;

    return elt.options[elt.selectedIndex].text;
}

var text = getSelectedText('test');
