ReactJS: Display value in Alert

Question

I'm trying to create an alert with value, but it is always displayed like: [object object]

 alertify.confirm(
      "Confirm your data",
      utility._htmlToString(utility._html(utility.t("REGISTRATION_CONFIRM1"))) + <b>{formRegistrazione.values.FiscalCode}</b>,

this {formRegistrazione.values.FiscalCode} is displayed like [object object], how can I display the value?

Answer 1

alertify.confirm(
  'Confirm Message' + {formRegistrazione.values.FiscalCode}</b>, 
  () => { alertify.success('Ok') }, 
  () => { alertify.error('Cancel')}
)

Answer 2

Your object - formRegistrazione.values.FiscalCode - should have at least one key/value pair. ie,

const FiscalCode = { foo: 'bar' }

So to print the value 'bar' you would type formRegistrazione.values.FiscalCode.foo.
