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 selectElt.namedItem('value')
is equivalent to selectElt.options.namedItem('value')
.
<form>
<select id="myFormControl">
<option id="o1">Opt 1</option>
<option id="o2">Opt 2</option>
</select>
</form>
let selectElt = document.getElementById("myFormControl");
elem1 = selectElt.namedItem("o1");
But, you cannot write:
let selectElt = document.getElementById("myFormControl");
elem1 = selectElt.o1;
elem1 = selectElt["o1"];
