推荐答案

您可以使用工厂而不是简单的服务，并在其上创建一个 reset 方法，将其设置为初始状态".

You could use a factory instead of simple service and create a reset method on it which would set it to its "initial state".

例如，您的工厂可能如下所示:

For example, your factory could look something like this:

function MyFactory() {

    // generate the initial structure of the service
    let Factory = _getDefaultFactory();

    // expose the service properties and methods
    return Factory;

    /**
     * Reset the factory back to its default state
     */
    function reset() {
        // generate the initial structure again
        // and override the current structure of the service
        Factory = _getDefaultFactory();
    }

    /**
     * Generate a default service structure
     */
    function _getDefaultFactory() {

        return {

            // include the reset method so you can call it later
            // e.g. MyFactory.reset();
            reset: reset

            // include other factory properties and methods here

        };

    }

}
