Is there an alternative to using Gmaps.loadMaps when loading HTML/JS that contains Gmaps4Rails via AJAX?

I'm using Gmap4Rails in the body of a form that is loaded via Ajax. There are custom fields in the form and some of them may be location pickers that I have working on a non-Ajax version of开发者_运维问答 the form.

With the Ajax version of the form, I'm getting "Gmaps.my_map_id" undefined errors.

In the non-Ajax version of the form, I call Gmaps.loadMaps via JavaScript in the HTML page head for "window.onload" as is the normal practice with Gmaps4Rails.

However, this won't work in the context of Ajax, as the map(s) haven't been defined at window.onload time.

In my form, I also define a callback per Gmaps map object. This is what seems to be failing with the "undefined" error, even when I do a "Gmaps.loadMaps();" script directly before the first callback is defined in the code that is loaded by Ajax.

Basically it goes like this in code order:

1. in a loop, gmaps4rails partial is called to output each map custom field
2. after that loop finishes, Gmaps.loadMaps() is called once
3. in another loop, each Gmaps map object has the JS for its callback added

Any suggestions on how to get this working?

UPDATE: possibly only partly correct (i.e. I did have the problem that was outlined here, but calling Gmaps.loadMaps() still doesn't work).

2nd Update: I have had to alter the definition of the load_... to be on the Gmaps object and then alter Gmaps.loadMaps function accordingly. I've put in a pull request to the project at https://github.com/apneadiving/Google-Maps-for-Rails/pull/94.

The Gmaps.loadMaps() call wasn't the issue. So an alternative isn't necessary. The thing that was tripping me up is that in the partial enable_js was being called as false and the JavaScript that declares the new instance of the Gmaps4RailsGoogle and the function for loading it was not being called.

I have a custom version of the partial and in my case, even when enable_js (I interpret as "don't load javascript library files" for my app) is false, I still do the JavaScript that declares the new Gmaps4RailsGoogle instance and defines the load_... function.

That being said, the load_... function appears to be not working for me. It comes back with the following in my case:

TypeError: 'undefined' is not a function (evaluating 'window"load_" + key')

When I call the load_... function directly from the console (rather than the Gmaps.loadMaps call), I get a similar error:

"'undefined' is not a function (evaluating 'this.load_...()')"

Perhaps having to do with not having any markers declared? Any hints on that problem appreciated.

If I step through the steps in the load... function, the first bit that throws an error is .initialize(). Still investigating.
