Question

我正在做一个非常标准的地图加载，例如：

 map = new Microsoft.Maps.Map(document.getElementById('map_canvas'));

在Chrome中它运行正常，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＆＃39; matchMedia＆＃39;

Bing地图代码中的行是：

return window.matchMedia("(-ms-high-contrast:active)").matches

定义了窗口变量，但如果我检查它，则matchMedia未定义。

整个堆栈跟踪是：

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'matchMedia'

感谢您的帮助！

Answer 1

Internet Explorer 11 should support matchMedia。因此，最可能的原因是文档正在non full standard mode中解析。可能是因为您未在HTML顶部指定doctype，例如：

<!DOCTYPE html>

作为最顶层的HTML行。

另一种可能性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。如果此标记存在，请尝试删除它。如果它不存在，请尝试添加

<meta http-equiv="X-UA-Compatible" content="IE=Edge">

确保IE正在使用最新模式。 Read more here.
