Basemap Gallery Widget not populating!

EricPollard2 — Wed, 30 Apr 2014 21:17:49 GMT

Hello - I am trying to get the basemap gallery widget to work with our story map. I am using the stock example of San Diego right now to try and add the basemap gallery widget. Currently we can get the widget in the map area, but cannot get the basemaps to populate. Any ideas ?! Thanks !

Hi Eric,

Tough to say, but I don't see the map constructor in the code you posted.

There is: "var map;" and "map: map" only.

I would compare what you have to the basemap gallery sample and look for differences.

Hope this helps!

If there is no map you can't see the basemap gallery.
Check out my code.

you see where it says map: map if there is no map it wont show.

var basemapGallery = new BasemapGallery({
          showArcGISBasemaps: true,
          map: map
        }, "basemapGallery");
        basemapGallery.startup();

I took out the part that constructs a new map, because if I leave that in it will add a new basemap over the top of the web map I am referencing in the config section of the application. So what I removed was :

[HTML]        map = new Map("map", {
          basemap: "osm",
          center: [-98.185272, 26.282376],
          logo: false,
          sliderStyle: 'large',
          zoom: 9,
        });
        [/HTML]

When I removed this, it removed the duplicated basemap that was put over the top of my web map, but are you saying that this is what is causing me to not see the basemap gallery now? How do I have this not create a brand new blank topo basemap over the top of the referenced AGO web map?
Thanks!!
Eric

Hi Eric,

I highly recommend reading the starter tutorials for the ESRI JSAPI.
Even though you are using a storymaps template, you really do need to know javascript basics before coding with our library.

Concerning your issue: it looks like the majority of your application logic exists in main.js, which you did not post.

I assume the map object is defined in main.js, which would most likely be out of scope if you were trying to access it from your main html. You also override any preexisting context by using "var map" at the beginning of your require block.

The starter tutorials address things like this. If you don't know much about scope and context, I also suggest reading up on those concepts.

Hope this helps!

Thank you for the help. I am working through the tutorials and trying to figure this out. It looks like I will need to move most of the functionality of the basemap gallery to the javascript file and then just insert it with a <div> in the HTML. Still trying to make sure the map that gets called up in the basemap gallery code is the existing web map from AGO and not a new "blank" basemap.
Appreciate the time and response!

I am having the same issue. Even when I copy the entire sample code from
https://developers.arcgis.com/javascript/jssamples/widget_basemap.html
and paste it into a new html file, the BasemapGallery does not populate. What am I doing wrong????

Are you hosting the application using something like IIS?

Hi Erik,

Where you able to accomplish this? I'm having the same problem. Where did you create the parser to reference to only one map (div).
