Working with dropdown list items in JavaScript
Let us have a reference to the option
tag in a variable. For example, obtained as
follows:
let select = document.querySelector('#select');
let option = select[0];
In this case, the text property will store
the text of the option, the value property
will store the value of the attribute of the same
name, and the selected property will store
the value of true or false depending
on whether the list item is selected or not:
console.log(option.text);
console.log(option.value);
console.log(option.selected);
Go through the list items in a loop and add an exclamation mark to the end of the text for the selected item, and a question mark for unselected items.
