Improve this Doc View Source ngMaxlength

  1. directive in module ng

ngMaxlength adds the maxlength validator to ngModel. It is most often used for text-based input controls, but can also be applied to custom text-based controls.

The validator sets the maxlength error key if the ngModel.$viewValue is longer than the integer obtained by evaluating the Angular expression given in the ngMaxlength attribute value.

Note: This directive is also added when the plain maxlength attribute is used, with two differences:
  1. ngMaxlength does not set the maxlength attribute and therefore HTML5 constraint validation is not available.
  2. The ngMaxlength attribute must be an expression, while the maxlength value must be interpolated.
