@mixes <OtherObjectPath>

概述

The @mixes tag indicates that the current object mixes in all the members from OtherObjectPath, which is a @mixin.

示例

To start, we document a mixin with the @mixin tag:

Example of a @mixin

/**
 * This provides methods used for event handling. It's not meant to
 * be used directly.
 *
 * @mixin
 */
var Eventful = {
    /**
     * Register a handler function to be called whenever this event is fired.
     * @param {string} eventName - Name of the event.
     * @param {function(Object)} handler - The handler to call.
     */
    on: function(eventName, handler) {
        // code...
    },

    /**
     * Fire an event, causing all handlers for that event name to run.
     * @param {string} eventName - Name of the event.
     * @param {Object} eventData - The data provided to each handler.
     */
    fire: function(eventName, eventData) {
        // code...
    }
};

Now we add a FormButton class and call a “mix” function that mixes all of the Eventful functions into FormButton, so that FormButton can also fire events and have listeners. We use the @mixes tag to indicate that FormButton mixes the Eventful functions.

Using the @mixes tag

/**
 * @constructor FormButton
 * @mixes Eventful
 */
var FormButton = function() {
    // code...
};
FormButton.prototype.press = function() {
  this.fire('press', {});
}
mix(Eventful).into(FormButton.prototype);
