Javascript无法解析相对于当前脚本的工作路径 [英] Javascript not resolving worker path relative to current script

问题描述

我在 http：//localhost/js/foo.js 上有一个脚本，它需要从文件 http生成一个Web Worker： //localhost/js/fooWorker.js 。我以为我可以做这样的事情：

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')

但是，这会导致404错误，因为浏览器找不到 http：// localhost /fooWorker.js 。我的印象是工作路径相对于产生工作者的脚本被解析了，所以我不应该只能在同一目录中指定另一个.js文件的名称而不必提供绝对路径？我做错了吗？

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?
