Google Maps API：TypeError：a未定义 [英] Google Maps API: TypeError: a is undefined
问题描述
我在网上搜索了这个问题，他们都没有给我任何解决方案。我有一个简单的脚本来显示南非的地图。

< head>

< meta http-equiv =x-ua-compatiblecontent =ie = edge，chrome = 1/>

函数initialize（）
{
var mapOptions = {
center：new google.maps.LatLng（-29.09958,26.18434），
zoom：5，
mapTypeControlOptions：{
position：google.maps.ControlPosition.TOP_LEFT
}
};
map = new google.maps.Map（document.getElementById（'map-canvas'），mapOptions）;
}
google.maps.event.addDomListener（window，'load'，initialize）;
< / script>
< / body>
< / html>
但是我总是一遍又一遍地得到相同的错误。我甚至在不同的服务器上试过。
请帮忙
我也经常在最后几天看到这个错误，实验性API版本似乎存在问题。

I have searched this problem all over the web and none of them seem to give me any resolution. I have a simple script to just display the map of South Africa.

}

But I keep on getting the same error over and over. I have even tried on a different server.
Please help
I've also seen this error often in the last days, there seems to be an issue with the experimental API-version.
Load the release-version instead(basically you should always load the release-version in production)
