Detect changes on disabled field

Question

It seems propertychange events are ignored when a field is disabled. Is there a way to run code when the value changes?

<input id="country" onpropertychange="alert(country.value)" disabled="disabled"/>
<input type="button" onclick="country.value='USA'" value="Go" />

Answer 1

Could you not just add in your event inside the button's onclick attribute after country.value='USA'? For example:

<input id="country" disabled="disabled" />
<input type="button" onclick="country.value='USA'; alert(country.value)" value="Go" />
