Google Maps Api 3: Uncaught TypeError: Cannot call method 'setCenter' of undefined
提问by Mike Averto
I have been trying to get my geocoder working this morning for the following URL but can't seem to figure out what I am doing wrong: http://www.dlplaw.com/media/map.html
今天早上我一直试图让我的地理编码器为以下 URL 工作，但似乎无法弄清楚我做错了什么：http: //www.dlplaw.com/media/map.html
When clicking encode, the geocoder is doing it's job and returning the correct Lat / Long coordinates but it gets hung up on setCenter.
单击编码时，地理编码器正在执行其工作并返回正确的纬度/经度坐标，但它在 setCenter 上挂断了。
Uncaught TypeError: Cannot call method 'setCenter' of undefined
I tried to follow the Google example here and can't understand why this won't work: http://code.google.com/apis/maps/documentation/javascript/examples/geocoding-simple.html
我试图在此处遵循 Google 示例，但不明白为什么这不起作用：http: //code.google.com/apis/maps/documentation/javascript/examples/geocoding-simple.html
Thanks in advance.
提前致谢。

mapis not in scope. You declare maptwice – once in the global scope and once in initialize, but you only set the mapin initialize(the global mapis shadowed).
map不在范围内。你声明了map两次——一次在全局范围内，一次在 中initialize，但你只设置了mapin initialize（全局map被遮蔽）。
Remove the varfrom var map = new google.maps.Map(...);(but not the var map;at the top).
删除varfrom var map = new google.maps.Map(...);（但不是var map;顶部）。
