mapValidationMetadata - Methods - Questions API

Questions API Methods


Returns metadata for the question instance mapped to responses. This should only be used on validatable questions that can have multiple response areas. The metadata being mapped should be an array within metadata. For information about using this function to display distractor rationale, view this tutorial.

If successful, returns an object literal containing arrays that are keyed by "correct", "incorrect", and "unattempted". Each item in these arrays is an object that contains value property that holds the response value; an index property that refers to the shared index of both the response area and the metadata value; and metadata property that contains the metadata value.

Returns false if the all the necessary data doesn't exist, e.g. non-existent metadata, or question does not contain multiple response areas, etc.

Note For more information, see this tutorial article.
