check if a drop down list box has been edited

Hi
How can I use javascript to check if a date drop down list has been edited? ie the date selected in it has been changed on the form?

Thanks

Save the initial value when the page is loaded, then check the current value against the saved value.

window.onload=getSelected;
var s;
function getSelected(){
  s=document.formName.selectName.selectedIndex;
}
function checkSelected(){
  if(s==document.formName.selectName.selectedIndex){
    alert('Select changed');
  }
  else {
    alert('Select did not change');
  }
}
