<权限被拒绝>尝试实例化 Web Worker 对象时出错

问题描述

第一次尝试网络工作者 API，似乎无法得到后台工作者的响应.

Trying out the web worker API for the first time and can't seem to get a response from the background worker.

标记:

<script src="~/Scripts/script.js"></script>
<button onclick="TriggerWorker()">Trigger Worker</button>

script.js 文件内容:

Contents of script.js file:

function TriggerWorker() {

    var myWorker = new Worker('worker.js');

    myWorker.onmessage = function (e) {
        console.log(e.data);
    }

    console.log(myWorker);

    myWorker.postMessage("Text sent to worker");
}

worker.js 文件内容:

Contents of worker.js file:

onmessage = function (e) {
    postMessage('OK');
}

我可以让 myWorker 对象写入控制台，但响应OK"永远不会让它回到控制台.检查 myWorker 对象时，可以看到 onmessage 属性设置为权限被拒绝".

I can get the myWorker object to write to the console, but the response "OK" never makes it back into the console. When inspecting the myWorker object, I can see that the onmessage property is set to "Permission denied".

推荐答案

包含 worker onmessage 声明的文件的路径是相对于 html 文件 - 而不是调用脚本文件.

The path of the file containing the worker onmessage declaration is relative to the html file - not the calling script file.

我通过进行以下编辑使其正常工作:

I got it working by making the following edit:

var myWorker = new Worker('../Scripts/worker.js');
