AbstractWorker.onerror

概述

AbstractWorker接口的onerror特性是一个事件句柄，在 Worker的error (en-US)事件触发并冒泡时执行。

语法

myWorker.onerror = function() { ... };

示例

下面的代码片段展示了通过 Worker() 创建 Worker 对象的过程， 以及设置onerror回调函数：

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

myWorker.onerror = function() {
  console.log('There is an error with your worker!');
}

规范

浏览器兼容性

BCD tables only load in the browser

早期浏览器会抛出 SecurityError，在规范变更后，则是  error (en-US) 事件。具体见 Loading cross-origin worker now fires error event instead of throwing; worker in sandboxed iframe no longer allowed.
