MGRS Geocoder Issue

StevenGraf1 — Fri, 12 Sep 2014 14:38:26 GMT

I'm trying to use the custom geocoder widget to zoom to a USNG coordinate and not having much luck. It keeps throwing an init.js error.

I am using the custom geocoder widget that I modified slightly. I thought maybe I need to project the map to the same spatial reference as the geocoder so i added that in.

Here is a fiddle: Edit fiddle - JSFiddle

Thanks!

Maybe this can help?

That's where I started at first and was able to pull out the zoom to usng part of it, but it was still throwing me an error although working at the same time. I don't remember if I saved the error as it was a few weeks ago.

I decided to see if I could get the customer geocoder widget to work with the MGRS geocoder because that's the only aspect of your fiddle that I need.

Thanks!

Steven,

do you need to do it through the geocoder or can you do it through a textbox like i have it?

Either way would be fine.

Thanks for your help!

Thanks so much!

So basically you are just passing a string through a text box on to the locator?

Any reason you can think of that the geocoder wouldn't work?

Yes thats right.

I have no idea why the geocoder would not be working, When I use the debugger it does not return anything after I run the geocoder.
