WorkerGlobalScope
interface returns the
WorkerNavigator
associated with the worker. It is a specific navigator object, mostly a subset of the
Navigator
for browsing scopes, but adapted to workers.
var navigatorObj = self.navigator;
A
WorkerNavigator
对象。
If you call the following
console.log(navigator);
inside a worker (which would basically be the equivalent of
self.console.log(self.navigator);
, as these are being called on the worker scope, which can be referenced with
WorkerGlobalScope.self
), you will get a
WorkerNavigator
object written to the console — something like the following:
Object {onLine: true, userAgent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) Ap…ML, like Gecko) Chrome/40.0.2214.93 Safari/537.36", product: "Gecko", platform: "MacIntel", appVersion: "5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKi…ML, like Gecko) Chrome/40.0.2214.93 Safari/537.36"…}

__proto__: Object
You could use this navigator object to return more information about the runtime envinronment, as you might do with a normal
Navigator
对象。
