detect dropdown changes

[yonghan]

Hi all,i'm wondering how to detect select option changes.For example i want the data in database changed when i click on update button and if there are changes on the select option side.If the values on the select option are not changed,i can't update the data..Is there a way to achieve it?Thanks a lot...

You'll can use the onchange event.

<select onchange='someJavaScriptfunction()'>...

Actually i look at the virtuemart that they implement that way,where if the select option value is not changed,then i can't update the order status and it will show message that there are no changes ..The update button was a submit button i suppose..I'm intending to follow it..Thanks...
