Just noticed that the BaseMapToggle widget has properties renamed... found this thanks to the helpful error messages when using Typescript. Used to be for 4.10 as follows... let basemapToggle = new BasemapToggle ( { view : view , secondmap : "satellite" } ) Now, it's let basemapToggle = new BasemapToggle ( { view : view , nextBasemap : "satellite" } ) Not a big deal but I didn't see that in the Release Notes. Is there a place to note observations like this that may be missing from documentation?

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

BaseMapToggle widget is different in 4.11...

Just noticed that the BaseMapToggle widget has properties renamed... found this thanks to the helpful error messages when using Typescript. Used to be for 4.10 as follows...

<SPAN class="keyword token">let</SPAN> basemapToggle <SPAN class="operator token">=</SPAN> <SPAN class="keyword token">new</SPAN> <SPAN class="token class-name">BasemapToggle</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">{</SPAN>

Now, it's

<SPAN class="keyword token">let</SPAN> basemapToggle <SPAN class="operator token">=</SPAN> <SPAN class="keyword token">new</SPAN> <SPAN class="token class-name">BasemapToggle</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">{</SPAN>

Correct the widget never had either a secondmap or secondBasemap property. I think it just looked like it was working because if the nextBasemap property isn't set a default base map (hybrid) is used. The thumbnail for hybrid looks similar to the one specified in the tutorial (satellite) so it gives the impression that it is working.

I'll contact the team who built the tutorial and let them know its incorrect.

Thanks, Kelly - now I get it. Either way, I'm glad that by use of Typescript and the jsapi types, I was alerted to this!

Okay, I'm confused.... it's quite possible that I got it backward though. This is what I was using before and which seemed to work. (Source: https://developers.arcgis.com/labs/javascript/select-a-basemap/ ) .

In the main function, create a BasemapToggle widget. Set the view and the secondBasemap property to satellite.

var basemapToggle = new BasemapToggle({     view: view,     secondMap: "satellite"   });

Interestingly, the text says 'secondBasemap' and the code 'secondmap'. Both wrong? So are you saying they never existed? Anyway, like I said, it's working after I changed it to nextBasemap.

khutchins

The property to select the alternate basemap has always been nextBasemap. We haven't had a property called secondmap. You can see nextBasemap working in this code pen but if you switch to secondmap it will use the default alternate basemap instead of the specified one (national geographic).

The code pen above is pointing to 4.10.
