This validator compares the specified input datetime with another one and make sure if their relationship is as specified by the operator property.

• compareAttribute: the name of the attribute whose value should be compared with.
• compareValue: a constant value that the input value should be compared with. When both of this property and compareAttribute are specified, this property will take precedence.
• operator: the comparison operator. Defaults to =. The following operators are supported:
  • =: check if two values are equal. The comparison is done is non-strict mode.
  • !=: check if two values are NOT equal. The comparison is done is non-strict mode.
  • >: check if value being validated is greater than the value being compared with.
  • >=: check if value being validated is greater than or equal to the value being compared with.
  • <: check if value being validated is less than the value being compared with.
  • <=: check if value being validated is less than or equal to the value being compared with.
• format: Date format to parse values with. Defaults to Y-m-d.
• jsFormat: Date format to parse values with client side. Defaults to YYYY-MM-DD.
