什麼是共享工作者？工人與共享工人有什麼不同？

Question

我不得不看共享工人的例子。但我無法確定工人與共享工人之間的差異。 共享工作人員示例https://github.com/mdn/simple-shared-worker。 任何人都可以請解釋一下嗎？

Answer 1

Worker和SharedWorker的工作流程如下。工人和共用工作之間

Difference between Worker and SharedWorker

類似的特徵。

The Worker works in another thread. So it's not affecting the main thread. So that time users can scroll, view the page without blocking. 

1. Worker can't access DOM elements from the web page. 
2. Worker can't access global variables and functions from the web page. 
3. Worker can't call alert() function. 
4. Objects such as window, parent, document can't be accessed inside the worker. 

工人自己的功能。

Workers life time between page creates and closure. Once the page creates the new workers will be created. View first image that blog diagram says about Wokers. 

共享工作者自己的功能。

共享工作者連接來自同一個域的所有網頁。查看博客圖表中關於Wokers vs Shared Workers的第二張圖片。
