The HTMLSelectElement.namedItem() method returns the HTMLOptionElement corresponding to the HTMLOptionElement whose name or id match the specified name, or null if no option matches.
In JavaScript, using the array bracket syntax with a String, like selectElt["value"] is equivalent to selectElt.namedItem("value").
var item = collection.namedItem(str); var item = collection[str];
DOMString

<option id="o2">Opt 2</option>
</select>
</form>
elem1 = document.forms[0]["myFormControl"]["o1"]; // Returns the HTMLOptionElement representing #o1
