Vue Validator - CompareRule

A validation rule that demands that a validated editor has a value that is equal to a specified expression.

Type:

Object

To specify the expression that the validated field must match, set the rule's comparisonTarget configuration option. Assign a function to this option. The validated value will be compared to the function's return value. The comparison will be performed by using the operator that is set for the comparisonType option.

You do not have to specify this field. In this instance, a default message will be shown. To include the name of the validated editor into the default validation message as a subject, set the name field of the dxValidator object.

If you assign an empty string to the message field, the message will not be shown.
