How to get value in option when selected, via jquery?

Question

JavaScript

<select id="selectYear">
<option>Все</option>
<option>1999</option>
<option>2000</option>
<option>2001</option>
<option>2002</option>
</select>

I’ll clarify: how to make it so that when you click on an option, an alert appears with the text from the option.

Answer 1

$('#selectYear').change(function() {
    alert(this.value);
});
