Bing 地图 v8 未加载 IE11
Bing maps v8 not loading for IE11
我正在执行非常标准的地图加载，例如：
map = new Microsoft.Maps.Map(document.getElementById('map_canvas'));
在Chrome中它工作正常，但在IE11中，我在地图代码中遇到异常：
0x800a01b6 - JavaScript 运行时错误：对象不支持 属性 或方法 'matchMedia'
Bing 地图代码中的行是：
return window.matchMedia("(-ms-high-contrast:active)").matches
window 变量已定义，但如果我检查它，则 matchMedia 未定义。
整个堆栈跟踪是：

感谢您的帮助！
Internet Explorer 11 should support matchMedia. Therefore, the most likely cause is that the document is being parsed in a non full standard mode。可能是因为您没有在 HTML 的顶部指定文档类型，例如：
<!DOCTYPE html>
作为最上面的 HTML 行。
另一种可能是您声明浏览器应使用兼容模式，例如使用 http-equiv="X-UA-Compatible" 元标记。如果存在此标记，请尝试将其删除。如果不存在，请尝试添加
<meta http-equiv="X-UA-Compatible" content="IE=Edge">
确保 IE 正在使用它可以使用的最新模式。 Read more here.
