<select id="Nazione" name="Nazione">
<option prefix='+93' value='AF' >Afghanistan </option>
<option prefix='+355' value='AL' >Albania </option>
<option prefix='+213' value='DZ' >Algeria </option>
<option prefix='+376' value='AD' >Andorra .... etc
</select>
and this js
$(document).ready(function() {
$('#Nazione').change(function(){
alert( $(this).find("option:selected").attr('prefix') );
alert( $(this).attr('prefix') );
});
});
I have alert NULL... WHy?
Your code is fine. Here's a demo : http://jsfiddle.net/hKktc/1/
The reason you're not getting a value for the second alert call is because the attribute prefix
doesn't exist for the select
and only exists for the option
