Inconsistent Zoom Behavior with URL Parameters

ArielLow2146 — Mon, 03 Oct 2022 16:53:52 GMT

I have a Media Map configured with a URL parameter.

When I append &district=20 to the app URL the first time it loads it shows the typical map extent but if I refresh the page it loads the app zoomed into the feature I've specified with the URL parameter. Loading the app zoomed into the feature is the behavior I'd prefer. Is there a way to get that to happen on the first app load?

I put together a sample app to try and repro. When I run this app for the first time with the url param and a custom zoom level applied (using the level url param) it zooms to the location and shows the popup. Is this app working for you:

Hi @KellyHutchins. Yes that app loads consistently at the same zoom level for me. When I load this app https://geo.maps.arcgis.com/apps/instant/media/index.html?appid=b085638a28ad4d1498c5777bca5bffe1&district=20 without the level parameter is when I see the different zoom behavior on refresh. I tried applying a level parameter but it also resulted in some different zoom levels occurring on refresh. I'll take a look to see if I can figure out some better repro steps.

Hi @KellyHutchins. I was able to reproduce the behavior I was seeing in the app I shared in my last response. To do so I:

Added the USA Census States layer to a map https://geo.maps.arcgis.com/home/item.html?id=774019f31f8549c39b5c72f149bbe74e
Zoomed to the extent of the layer and saved the map.
Clicked the Create App button in Map Viewer and chose Instant Apps then chose Media Map.
Turned off express mode.
Configured the URL parameter as shown

When I publish and first view https://geo.maps.arcgis.com/apps/instant/media/index.html?appid=52f91e058bca4538a7aae359f1c5847b then add &fips=11 to the URL the first time it loads it is zoomed out but when I refresh it zooms in.

Thanks for the additional info. I'm working on debugging/testing this behavior out in the app today.

How/where are you configuring the url parameter here? In the map or in the app?

Thank you,

@RandyMcGregor3 I was doing this in the Instant App configuration

Thank you. I had to search for 'URL Parameters' then got a message saying I would no longer be in the some sort of mode (Simple Mode or something) is that OK? and I said, 'Yes.' Thank you for making me aware of this. It appears that Instant Apps have more limited url-based modification options than Web App Builder apps.

Is there documentation about the url parameters available in Instant Apps (as opposed to Web App Builder Apps)? I have Googled and searched and not found any documentation.

Thank you,

In some apps you can define custom url params in the app configuration. In those apps you choose the layer and field name you want to use. The apps also support defining extent. center, level webmap (or webscene). find and marker. Details about using those params can be found here: https://doc.arcgis.com/en/arcgis-online/reference/use-url-parameters.htm

Here's where I may be missing something and sorry if I'm being slow. The parameters in that link for for web maps. I have been able to find url parameters for web maps and for web app builder web applications (and for dashboards - different configuration), but not for instant apps.

Thank you,

We don't have doc for this but the url params I mentioned in my post above can be used with instant apps and have the same format as those used by web apps in the Online document I linked to. For example here's the Basic instant app using the find url parameter

Is this only in AGO? I recently upgraded to Enterprise 11.0 and all of my "apps/embed" based web maps being used by outside department webpages got hosed. I am trying to identify a workaround using instant apps but can't figure out how to use URL parameters to zoom to a specific feature.
