So I'm stumped on this one. I've gone ahead and republished my map service in question here, and now I'm seeing even weirder behavior. But since it doesn't merely relate to the 'visible' property, I'll start a new thread. Thanks for chiming in, Dan. ... View more

Works for me when I try this: aString = "US20 EB <br> <br> FID 57 <br> RampDate 9/30/2013 \ <br> RouteId 161 <br> RouteName US20 EB <br> TownId 314 <br> \ TownName Watertown <br> IsMissingR False <br> IsMissingS False <br> \ IsMissingC True <br> InspNotes <br> DistrictId 6 <br> LegacyID \ 335 <br> status 6 <br> StatusText Deficient <br> DstrctRank 669 \ <br> deficient -1 <br> GlobalID {C4BBAA58-9DFE-4953-AC74-FF3448002388} \ <br> created_us <br> created_da <br> last_edite DAVID.DINOCCO \ <br> last_edi_1 10/17/2017 <br> ReInspectn 0 <br> AssetID <br> \ ProgNotes <br> Rank 669" aString.split("<br>")[14] >>> ' status 6 '‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ len(aString.split("<br>")) >>>27‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Something wrong with the field name?

Sorry ,,, never a good idea to tweak things in transition from IDE to Geonet... I'm flipping the attribute to its Boolean opposite, so it should read: layer.visible = not layer.visible If it was visible to begin with, I want to hide it, and the other around. Any idea why this would fail for some layers? Thanks, Dan. ... View more

So to refine my approach after re-reading the documentation on layer properties and methods, I try this: # ... while iterating over layers print("Layer Name: "+layer.name) print("Layer visible: ",layer.visible) print("Layer supports 'visible': ",layer.supports("visible")) if layer.supports("visible"): try: layer.visible = !layer.visible print("Switched Layer visibility") except Exception as e: print("Unable to switch visibility") print(e) print("Layer visible: ",layer.visible)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ On most cases, there result is as expected: Layer Name: My Well Behaved Layer Layer visible: True Layer supports 'visible': True Switched Layer visibility Layer visible: False‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ But in other cases, I get this: Layer Name: My Poorly Behaved Layer Layer visible: True Layer supports 'visible': True Unable to switch visibility The attribute 'visible' is not supported on this instance of Layer. Layer visible: True‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ It seems that it the layer says it supports 'visible', it should do so. Would love to know how to make sense of this. ... View more

Tanu Hoque‌, Noah Sager‌ - so I've looked at this again, and notice that in the JSON under operational layers, in fact, I get this... "operationalLayers": [ { "id": "defaultBasemap", "title": "World Topographic Map", "opacity": 1, "minScale": 0, "maxScale": 0, "url": "https://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" }, { "id": "My_Map_365", "title": "My_Map", "opacity": 1, "minScale": 0, "maxScale": 0, "url": "HTTPS:// ...<MapService URL>", "layers": [ { "id": 1, "layerDefinition": { "source": { "type": "mapLayer", "mapLayerId": 1 } } }, { "id": 2, "layerDefinition": { "source": { "type": "mapLayer", "mapLayerId": 3 } } }, ...MORE ...‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Since I'm trying to consume the JSON in a GP Service. The easiest to do is just to drop the "layers" key entirely. That way the GP service gets fed all the sublayers of the Map Services, which is specific by URL, and I weed through what I want to show using Python. Didn't realize this was working. I saw the additional layers and thought only those showing were passed through. If I leave the "layers" key, then I end up with duplicate layers on the Python side of the fence, which makes it unworkable. Anyway, thanks for chiming in. Now, I just need to figure out why some layers refuse to turn of using arcpy. ... View more

Just what I needed. As someone who is constantly learning new Javascript stuff and API hacks at the same time, I was playing with ... document.getElementById("myElement").style.cursor = "<pointer-style>";‍‍‍ But the above did the trick for me! ... View more

Haha - sorry for not speaking more clearly, Noah. Basically, I want to capture the JSON for the current webmap in a variable... let webMapAsJSON = printTask._getPrintDefinition(currentMap, params); let webMapAsJSONasString = JSON.stringify(webMapAsJSON); ... then I want to sneak in the JSON for some layers that are belong to the underlying webmap coming out of Portal but without modiifying what's showing in the map. (Working on custom widget for WAB, so I'm getting my map services via reference to a webmap item in Porta,.) I've been playing with some Javascript to basically add/modify portions of the JSON myself. I had merely hoped somebody had some ArcGIS specific snippets to share. ... View more

Let me modify the direction of my inquiry as I've thought through this further. So I have an event handler hooked up to a button that calls my printTask. I can make this same event add any layers to the map that I want passed in the JSON. But that has the seemingly inexplicable effect for the user why different layers now showing up in map and/or legend. Is there a simple way to grab the JSON, replace/update the layer info I want include and then feed it into my GP processing service, thereby avoiding the map refresh/change? Right now, the only way I can envision is by brute force string manipulation.  ... View more

Rebuilding from scratch a 3rd of 4th time, finally did the trick. Oh how I wish that error messages were a little more helpful when working with the JSAPI. ... View more

Still haven't had time to try this but I will report back after doing so eventually. ... View more

Never did get the selectFeatures() to work so I resorted to a work-around, simply iterating over the features which queryFeatures() would return and making them into Graphics one by one. Then adding them to map.graphics‍ Seems these days that half the things i try to do don't work out the way that my interpretation of the documentation says it should. In the end, what matters though are result and work-arounds do the job. ... View more

Cool, thanks, Your one-liners are like fresh batteries in the caverns of ESRI documentation. Haha. Also. I just found that I may be complicating matters by using the result from a Search (with suggestions) to get my buffer center point and that seems to default to a WKID different from what's in my service. Not sure but I'm going to try to fix that it needed,. ... View more
