未捕获的ReferenceError：未定义Gmaps

Question

I'm using Gmaps4rails with Foundation 5. I followed the Gmaps4rails video tutorial and the map is not showing up. I'm getting the Uncaught ReferenceError: Gmaps is not defined and the offending line is the first line of the custom script:

handler = Gmaps.build('Google');

I assume there's some kind of conflict with Foundation because I tried creating a Rails app with only Gmaps4rails and no Foundation and everything works fine.

Answer 1

According to the sample app, the issue is the following: you call Gmaps before the script containing its definition is loaded... it cant work.

Explanation is you put = javascript_include_tag "application" at the bottom of your html, to meet Foundation's expectations. So every previous javascript will fail: you have to put your scripts after the files defining them.

So AFTER = javascript_include_tag "application" , add:

= yield :scripts

And then whenever you need in a view:

- content_for :scripts do
 :javascript
   // Gmaps can be called safely here...
