click event


Initiates when a mouse click occurs within the region. When a click event initiates for a text or numeric field, calculations or scripts execute immediately. However, the value of the field does not change in response to calculations and scripts until the field loses focus.

Note: You cannot place a calculation or script on the click event of a submit button because the calculation or script will override the submission action. Instead, place any calculations and scripts on the preSubmit event for a submit button. For more information about form submission actions, see the Designer Help.
