If you are adding custom code to your APS app, from the low code editor (activiti-app), and you need to access a specific field on your form, you can do it using the scope parameter, available from one of many customizable functions.
Use the following JavaScript code inside a form function to get the value from a field whose id is “field-id”. One of the function parameters must be scope, that will provide access to the fields.
scope.findFormFieldWithId(scope.allFormFields,"field-id").value
Some of the out-of-the-box functions that have scope as a parameter are listed as follows:
formRendered:function(form, scope)
