Get the ID of a lookup field

Mar 16, 2015 at 2:41 AM
It looks like GetValue() returns the text value (description) of the drop down. Is there a way to get the "value" (ID) of the selected item?

You are correct. If you'd like get the ID of the current selected item in the dropdown, you could use the Dropdown property.

For example:
var f = SPUtility.GetSPField('Dropdown Choice');
var index = f.Dropdown.selectedIndex;
// index is selected index of the dropdown
