Getting values from multi select option in DCR

I have a multi select option in dcr. I want to reterive all the multi selected values in the presentation template. I've tried using this function in the FormAPI but it only returns the first value.

function checkVenueOptions (item) {

var venue_option = item.getName();

var ven_ops = IWDatacapture.getItem(venue_option).getValue();

for (var i = 0; i < ven_ops.length; i++) {

var venue_value = item.getOptions()[parseInt(item.getValue())].value;

alert(ven_ops);

}

Am I missing something? Thanks.

Hard to say without seeing the relevant piece of the DCT, but asking for item.getValue() inside the loop doesn't really make sense, especially if "item" refers to a multiselect list. Perhaps you meant to use ven_ops[i] instead?

OK - I took out the loop and replaced it with the following code. It works fine if I select just one value but nothing displays when I select mulitple values.

function checkVenueOptions (item) {

var venue_option = item.getName();
var ven_ops = item.getOptions()[item.getValue()].value;

alert(ven_ops);

return true;

}

That's just farther from the answer.

When "item" is a multi-select, the item.getValue() call will return an array of selected indicies. Thus, your code should look like this:

function checkVenueOptions (item) {
  var itemOptions = item.getOptions();
  var itemValues = item.getValue();
  for (var i=0; i<itemValues.length; i++) {
    var selectedOption = itemOptions[itemValues[i]].value;
    alert(selectedOption);
  }
  return true;
}

Thank you! That works great.

OR,

var test = item.getName();

 for (var i = 0; i < test.getOptions().length; i++) {
     if(test.getOptions()[i].selected ==true){ 
          alert(test.getOptions()[i].value);
      }

  }
