Javascript 使用'；谷歌地图API'；在网络工作者中

我试图在Javascript Web Worker中加载GoogleMapsAPI，但它无法加载地图库。Web Worker代码如下所示：

importScripts('http://maps.googleapis.com/maps/api/js?libraries=geometry&key=MYAPIKEY&sensor=FALSE'); 

这在一个简单的例子中失败了

Script Error.

在Chrome中，当我尝试加载工人时

我假设maps库中有东西试图访问DOM。但这只是一个猜测。有人有解决办法吗

编辑： 我打开了上面的链接，试图提取并修改它的内容。因此WebWorker.js现在看起来像这样：

var window = {google: {}};
var google = {maps: {}};
(function() {

  function getScript(src) {
      importScripts(src);
    //document.write('<' + 'script src="' + src + '"><' + '/script>');
  }

  var modules = google.maps.modules = {};
  google.maps.__gjsload__ = function(name, text) {
    modules[name] = text;
  };

  google.maps.Load = function(apiLoad) {
    delete google.maps.Load;

但这仍然会导致“脚本错误”。

谷歌客户端api（如map、drive等）需要dom元素，因此您无法在web worker中使用map api。我在过去几个小时的研究中也遇到过类似问题，我确认至少目前无法完成。以下是有关web Wriker的几点您需要了解的内容

我们可以在web workers中访问的对象很少：

XMLHttpRequest、JSON、Worker、navigator、位置、设置和清除超时、导入脚本、设置和清除间隔

无法从Web worker访问窗口或父本地存储对象

我实际上已经能够创建一个标记实例，方法是愚弄工作人员，使其认为有一个DOM对象可供其使用。我从尝试在遇到相同问题的工作人员中使用jQuery命令的人那里学到了这个想法。我的参考资料如下：

// create a fake document for jQuery to function - DOES NOT PROVIDE ACCESS TO ACTUAL DOM ELEMENTS
// from Tomáš Zato comment on http://stackoverflow.com/questions/10491448/how-to-access-jquery-in-html-5-web-worker
var document = self.document = {parentNode: null, nodeType: 9, toString:function() {return "FakeDocument"}};
var window = self.window = self;
var fakeElement = Object.create(document);
fakeElement.nodeType = 1;
fakeElement.toString=function() {return "FakeElement"};
fakeElement.parentNode = fakeElement.firstChild = fakeElement.lastChild = fakeElement;
fakeElement.ownerDocument = document;

document.head = document.body = fakeElement;
document.ownerDocument = document.documentElement = document;
document.getElementById = document.createElement = function() {return fakeElement;};
document.createDocumentFragment = function() {return this;};
document.getElementsByTagName = document.getElementsByClassName = function() {return [fakeElement];};
document.getAttribute = document.setAttribute = document.removeChild =
  document.addEventListener = document.removeEventListener =
  function() {return null;};
document.cloneNode = document.appendChild = function() {return this;};
document.appendChild = function(child) {return child;};

我被困在这上面了
