I've tried getComponent("ComboBoxID").getChildCount() but that appears to not return the correct number. Anyone know if there is a method I can use? Or maybe a function needs to be created?
EDIT - And is there a way to loop through the options and get the values like in CSJS?:
for (var i = 1; i < comboBox.options.length; i++){ pmtPlan = comboBox.options[i].value; ...
