So I am currently writing an application using the ArcGIS JavaScript API, and I want to access the map object that is held inside of my div from a js module I have. I was thinking it would be a simple JQuery call but it doesn't seem to be the case, as when I try to use map.centerAndZoom(), it states that it is not a member of the object that returned by that call.

Is there anyway to be able to reference the map object that was created in my main index.html elsewhere?

I'm not an expert on this, so this may not be best-practise - I'll defer to more expert programmers to come up with a better approach.

But what I usually do is create a single global JSON object and hitch everything off this. eg:

var myObject = {};
myObject.map = new Map("map", {.....});
myObject.layers = {.....};

You can access this object using window.myObject:

window.myObject.map.centerAndZoom(...);

I ended up just using map = new Map() instead of var map = new Map(). Making it global seemed to do the trick. –  Logan Lehman Jun 10 at 3:48

After further research, I don't believe it is possible. Instead, I created a global variable to access the map that way.

map = new Map()

instead of

var map = new Map()
