根据架构的其他部分，您可能希望使用Dojo的pubsub模块dojo/topic：
https://dojotoolkit.org/reference-guide/1.10/dojo/topic.html
例如，将代码更改为：

define("mySolution/ServerCookieWidget", [
    "dojo/request/notify",
    "dojo/cookie",
    "dojo/topic"
], function (notify, cookie, topic) {
    notify("load", function(response) {
        var cookieRead = cookie("myCookie");
        // console.log('Cookie read is: ', cookieRead);
        topic.publish("*/cookie/value", cookieRead);
    });
});

您可以创建订阅主题的小部件：

define("mySolution/SomeOtherWidget", [
    "dojo/_base/declare",
    "dojo/topic"
], function (declare, topic) {
    var OtherWidget = declare(null, {
        constructor: function (opt) {
           this.topicHandle = topic.subscribe("*/cookie/value", this._handleCookieValue.bind(this));
        },
        _handleCookieValue: function (cookieVal) {
            console.log("Cookie value is:", cookeVal);
        }
    });

    return OtherWidget;
});
