Fieldset » assertAllTouched

assertAllTouched()
assertAllTouched(options)
assertAllTouched(message, options)
assertAllTouched(messageFunction, options)

Assert that all entries of this fieldset that were present in the parsed eno document were also queried (and therefore touched) by the application. This, combined with eno's query methods, serves to ensure a two-way guarantee for both users and developers: No data that the application requires can be left out, and no data that the application does not process can be supplied.

enoImportant data:
A = I need to be processed!
B = Me too!

javascriptconst document = eno.parse(input);
const fieldset = document.fieldset('Important data');

const dataA = fieldset.entry('A');

// ... processing happens only for dataA

fieldset.assertAllTouched(); // throws an error

fieldset.assertAllTouched({ only: ['A'] })  // passes
fieldset.assertAllTouched({ except: ['B'] })  // passes

fieldset.assertAllTouched(({ name, value }) =>  // throws an error "B is not ..."
  `${name} is not supported by the application, please contact support if you think it should be`
);

Parameters

Optional, usually the default message (An excess element named [NAME] was found, is it possibly a typo?) will do fine. If you want to override it, provide either a static message as a string, or alternatively a function returning a string. (The function is passed name and value inside a single object parameter.)

only

An array of strings, e.g. ['name', 'email'], which specifies to only check these elements for whether they've been touched.

except

An array of strings, e.g. ['phone number'], which specifies to exclude these elements from checking whether they've been touched.
