此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。
console
只读特性在
WorkerGlobalScope
interface returns a
控制台
object providing access to the browser console for the worker.
var consoleObj = self.console;
A
控制台
对象。
This property allows you to have access to a browser console for debugging purposes, inside a worker. So for example you could call
console.log('test');
inside a worker (which would basically be the equivalent of
self.console.log('test');
, as these are being called on the worker scope, which can be referenced with
WorkerGlobalScope.self
), to return a test message out to the browser console.
If you are calling
console.log()
从
DedicatedWorkerGlobalScope
or other worker scope that acts on a single loaded window, that tab's web console will receive the logs. However, If you are calling
console.log()
从
SharedWorkerGlobalScope
, the global browser console will receive the logs.
