Returns the number of the image area clicked by the Web user.
This function can only be used in the click code of a Clickable Image control (control with an action set to "Clickable areas defined in edit mode (Image map)" in the "General" tab of the control description window).
// Click on IMG_IMAGE1
n is int = ImageArea()
CASE 0: STC_Caption1 = "External area"
CASE 1: STC_Caption1 = "Area 1"
CASE 2: STC_Caption1 = "Area 2"
Number of the clicked area. This number is undefined if ImageArea is used in an event other than the "Click" event of an Image control.
Remark: In the "General" tab of the Image control description window, "Action on click" corresponds to "Clickable areas defined in edit mode (Image map)".
If your project uses pre-launched sessions, this function must not be used in the project initialization event. This function must be used in the "Initializing the project after connection to the site" event.
