AngularJS: API: ngMessages/directive/ngMessages


ngMessages

  1. - directive in module ngMessages

ngMessages is a directive that is designed to show and hide messages based on the state of a key/value object that it listens on. The directive itself compliments error message reporting with the ngModel $error object (which stores a key/value state of validation errors).

ngMessages manages the state of internal messages within its container element. The internal messages use the ngMessage directive and will be inserted/removed from the page depending on if they're present within the key/value object. 默认情况下, only one message will be displayed at a time and this depends on the prioritization of the messages within the template. (This can be changed by using the ng-messages-multiple on the directive container.)

A remote template can also be used to promote message reuseability and messages can also be overridden.
