First of all, an existing widget must be identified in the dashboard to be the target of the triggered action, of which the id <TARGET_WIDGET_NAME> must be noted. In this example the target is a WidgetSingleContent.

The JavaScript function to be inserted in the appropriate CK Editor box (in more options) of the current widgetImpulseButton widget is of the following type:

 

function execute() {

       $('body').trigger({

             type: "showLastDataFromExternalContentGis_<TARGET_WIDGET_NAME>"

             eventGenerator: $(this),

             targetWidget: <TARGET_WIDGET_NAME>,

             color1: "#acb2fa",

             color2: "#231d5c",

             widgetTitle: "Occupied Parking Lots (Alberti Car Park)",

             field: "occupiedParkingLots",

             serviceUri: "http://www.disit.org/km4city/resource/iot/orionUNIFI/DISIT/CarParkPal.Giustizia"

       });

}
