Retrieving all option values from listbox

[SpeedStick]

Hi,

I'm working with a javascript function that allows you to move options back and forth between listboxes. This is working fine - however, when the form is submitted, I want to retrieve all the option values from one of the listboxes to see which values have been removed. Is there any way to retrieve the options of a listbox whether they are selected or not? Thanks....

Is there any way to retrieve the options of a listbox whether they are selected or not?

var listBox = document.getElementById('listboxID');
for(var i = 0; i < listBox.options.length; i++){
  if(listBox.options[i].selected == true){
    //do stuff
  }
}

pretty sure it goes something like that ...
