Google Maps api异步加载-尝试了所有解决方案-疯了

Question

I'm trying desperately to finish this project

http://kenziejoy.github.io/frontend-nanodegree-map/

(that is the gh-pages branch, the master is a little behind)

and while tinkering with other things my map disappeared...forever. I can't find what is wrong. I feel like I've tried everything: async, defer, async defer, callback to a function in the html that then calls a function in the js file (someone suggested it), initmap inside the viewmodel, outside the viewmodel, everything wrapped in a self running function.

Most of my errors are either, my callback isn't a function, google isn't defined or something in my js file isn't defined.

I've poured through to make sure it isn't something silly like a misplaced comma - but I'm getting so frustrated I've probably made a stupid mistake somewhere. Just any help would be really appreciated. At least so I can get a map up there and make some progress on everything else.

Looking at the code in your link In the app function in you main.js is not declared the googleMap var globally.

you must declare

var googleMap ;

in top of you main.js
