javascript - 是否可以在 WebWorker 中加载 JavaScript 文件？

Question

我有一个 WebWorker，我从它开始

new Worker("worker.js");

在这个 worker 中，我尝试通过以下方式加载所需的 JavaScript 文件，但没有成功

self.importScripts("NeededJs.js");
const m = new NeededJs();

如何解决这个问题并在我的 WebWorker 中包含所需的 JavaScript 文件？

编辑:

我收到错误消息:

Uncaught ReferenceError: NeededJs is not defined

谢谢

这是我需要包含的文件 File I need to Inlcude

是的，这是可能的。你应该注意到它是一个全局函数，所以删除 self.

Worker threads have access to a global function, importScripts(), which lets them import scripts. It accepts zero or more URIs as parameters to resources to import; all of the following examples are valid:

和

Note: Scripts may be downloaded in any order, but will be executed in the order in which you pass the filenames into importScripts() . This is done synchronously; importScripts() does not return until all the scripts have been loaded and executed.

此外，当您为导入的文件使用模块模式时，您需要传递一个选项来指定:

new Worker("worker.js", {type:"module"});
