Call class page function from element Event

You can Edit page class to add your custom functions.

To call these function in an element Event, for example, you may:

_ Add an attribute, for example (contextmenu) in the element and directly call the function:

this['my_custom_function']()
or
my_custom_function()

_ Add an Event component to the Element and fill it with (contextmenu). Add a CustomAction component as a child, call your custom function:

page['my_custom_function'](params);

You may need to add the following code to prevent default browser behaviour:

event.preventDefault();
