The change event is triggered by the field receiving focus, changing
value from whatever the defaultValue was, and then losing focus. Maybe
you could step through those events within the function that's
currently only changing the picker.
Or use a synthetic event, and have onchange on the picker set to fire
it along with your change function. Then you only need one piece of
code to observe the synthetic event.
document.observe('my:event',function(){ /*do something here*/ });
select id="myCars" onchange="$(this).fire('my:event');"
function foo(){
$('myCars').setValue('audi').fire('my:event');
}

Hi,
I have simple select box
<select id="myCars">
<option value="volvo">Volvo</option>
<option value="audi">Audi</option>
</select>
and my Javascript
$('myCars').observe('change', doSomething);
function doSomething(){
alert('doSomething');
}
In My code I want to programatically select "audi"... for which i do
$('myCars').value="audi"; // also tried other options like making
options selection true
This changes the selection in UI but doesn't trigger the onChange
event.
How can I fire the on change event programatically.
Thanks and Regards
Hari
