Parameter

Description
elementId

The ID or name attribute of the control.

attributeName

The control attribute to get; by default, the value attribute, or, for cfselect, the value of the selected element in the control.

For cftree controls, you must use this attribute and specify PATH or NODE. The function returns the item path or node value of the currently selected tree item.
