我做了一个webworker并尝试添加一个名为progress的自定义事件,如下所示:

self.updateProgress = function(no){
    let event = new CustomEvent(
        'progress',
        {
            detail : {
                description: "event from webworker to update progress",
                timeofevent: new Date(),
                eventcode: 15
            },
            bubbles: true,
            cancelable: false,
            data : no
        });
        self.console.log(self.dispatchEvent(event));
    };

在父JavaScript上:

scope.worker.addEventListener('progress', (e) => { //cannot add custom events to worker yet
    scope.progress = e.data;
});

问题是事件永远不会被触发,从我读过的内容来看,似乎消息和错误是唯一附加到worker对象的事件.是否无法添加自定义事件？
