"Use URL Parameter" to make visible Layers

deleted-user-CQZbjNeBXm49 — Tue, 22 Nov 2016 09:36:17 GMT

Hi all,

Please as anyone been able to use the instruction here "Use URL parameters" to make visible certain layers with their maps (dev: On-premise server deployment)? kindly guide someone in need.

Baba,

There is nothing in the url parameters that says you can set which layers are visible. What gave you that indication?

Robert,

There isn't, however, you can make certain layers visible using ArcGIS JavaScript API like here, I was think that might be possible when we deploy the app locally

Baba,

Nope that is not part of the WAB capabilities.

Robert,

The reason for the question is that in the share widget, the url (see image) shows a "?visiblelayer=" parameter but only that of the extent worked, so that got me curious

Baba

EDIT: As using the embed option look foolish if only the extent parameter works in the WAB Dev edition

Baba,

My only suggestion is to call support and file an enhancement request.

Hi. I've been working on this based on this ESRI document, which seems to elude to the fact that you can make layers visible using the URL. See 'Set Layer Visibility'. Use URL parameters to modify maps—ArcGIS Online Help | ArcGIS

Of course (as with most ESRI articles), the demonstration link works, but I have not been able to get this to work with one of my own web maps.

B Bulla,

Think your problem is that you are confusing the url abilities of the AGOL Map Viewer (which is what your link is referencing) and the supported url parameters of WAB:

Use URL parameters—Web AppBuilder for ArcGIS | ArcGIS

Perhaps, but shouldn't modifying the URL for a webmap and a webapp work basically the same? For example, using the /?find= with a wemapp URL and using &find= with a webmap URL both do the same thing.

So if I have a webmap that is used in a webapp, shouldn't I be able to turn a layer visible regardless of whether it is in a map or an app??

Hopefully that makes sense.

Actually No, As the only url parameters that are parsed from the url in WAB are those that are supported by the App and not all the one supported by the web map.

Re: "Use URL Parameter" to make visible Layers

BBulla — Wed, 22 Feb 2017 19:51:14 GMT

OK. I think I understand now. Each one has it's own specific parameters.

Thanks for your help.

I have spoken to the tech support from ESRI on this and they informed me that for a WAB Dev, the parameter to use will be the "?config=", where you had need to create new main config_name.json that will be referencing a new web map also or LocalLayer_config. See discussion here https://community.esri.com/thread/181279

It is a good workaround though it requires you to create webmaps and associated config files for each use case (the number of operational layers you need to show in individual URL )

It would have been great if the URL to services (operational layers) works directly like in the portal viewer.

Robert Scheitlin, GISP, I wonder what is the dataSource object in the config.json all about? there is a url parameter and is indicating some sort of Layers...

Mehretab,

Datasources are layer that are added to the application but NOT the map. They are available to widgets that use datasources like the infographic widget.

Thanks as always Robert.

cheers!!!

If anyone is still interested in turning layers on and off using url parameters and you're using the WAB developer edition, I've modified the url parameter handler module so you can toggle layers and sub layers on and off. I needed this functionality in an app I built and couldn't find a solution anywhere else. I posted about how to use it at https://ryandavison.net/toggle-layer-visibility-using-url-parameters-in-web-app-builder-developer-edition/ . There's a link at the bottom of the post to the updated module on Github.
