Javascript not resolving worker path relative to current script

问题

I have a script at http://localhost/js/foo.js which needs to spawn a Web Worker from the file http://localhost/js/fooWorker.js. I assumed I could just do something like this:

var worker = new Worker('fooWorker.js')

However, this results in a 404 error, as the browser cannot find http://localhost/fooWorker.js. I was under the impression that worker paths were resolved relative to the script spawning the worker, so shouldn't I just be able to specify the name of another .js file in the same directory without having to provide an absolute path? Am I doing something wrong?

回答1:

From http://www.w3.org/TR/workers/:

When the Worker(scriptURL) constructor is invoked, the user agent must run the following steps:

1. Resolve the scriptURL argument relative to the entry script's base URL, when the method is invoked.

回答2:

Actually, it should be relative to the embedded document path

For example,

I have

pathDoc\docA.html
js\b.js
js\worker\c.js

then code should be

var worker = new Worker('..\js\worker\c.js')
