@mixes <OtherObjectPath>
概述
¥Overview
@mixes 标签表示当前对象混合了 OtherObjectPath 中的所有成员，即 @mixin。
¥The @mixes tag indicates that the current object mixes in all the members from OtherObjectPath,
which is a @mixin.
示例
¥Examples
首先，我们用 @mixin 标签记录一个 mixin：
¥To start, we document a mixin with the @mixin tag:
/**
* 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...
}
};
现在我们添加一个 FormButton 类并调用 "mix" 函数，该函数将所有 Eventful 函数混合到 FormButton 中，以便 FormButton 也可以触发事件并具有监听器。我们使用 @mixes 标签来指示 FormButton 混合了 Eventful 功能。
¥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.
/**
* @constructor FormButton
* @mixes Eventful
*/
var FormButton = function() {
// code...
};
FormButton.prototype.press = function() {
this.fire('press', {});
}
mix(Eventful).into(FormButton.prototype);
