Mit dem Ausdruckseditor für Pop-ups aus einer Liste von Feldern mit JA- oder NEIN-Einträgen ein neues Feature erstellen

Anonymous User

Hallo zusammen,

Ich habe eine Webkarte in ArcGIS Online, deren Daten aus einem REST-Service stammen. Der REST-Service zeigt aktive Bauernmärkte in meinem Bundesstaat und listet auf äußerst umständliche Weise auf, in welchen Monaten die einzelnen Märkte geöffnet sind. Der angehängte Screenshot zeigt, dass für jeden Markt im Pop-up-Fenster zwölfmal ein JA- oder NEIN-Wert aufgeführt ist. Ich möchte all diese JA- und NEIN-Werte in einem neuen Feature zusammenfassen, das einfach angibt, in welchen Monaten der Markt geöffnet ist.

So sieht das Pop-up für diesen Markt in einem Dashboard aus, das die endgültige Anwendung dieser Karte sein wird.

Ich möchte lediglich, dass im Pop-up für jeden angeklickten Markt etwas in der Art von „Geöffnet im: Juni, Juli, August, September“ steht.

Ich sollte erwähnen, dass ich über meine Organisation keinen Zugriff habe, um Änderungen an deren REST-Service(s) vorzunehmen. Deshalb brauche ich eine Umgehungslösung.

Vielleicht verwende ich den Begriff „Feature“ als Lösung für mein Problem falsch – korrigiert mich also gern auch diesbezüglich. Meine Idee für eine Umgehungslösung war, die Funktionen „feature“ oder „featureset“ im Ausdruckseditor zu verwenden, um ein neues Feature zu erstellen, das auf die vorhandenen zwölf Monatsspalten für alle etwa 360 Märkte verweist. Seit ein paar Tagen versuche ich zu lernen, wie man einen Arcade-Ausdruck schreibt, der das erledigt, aber all die verschiedenen Funktionen bringen mich ganz durcheinander, und ich habe noch nie versucht, irgendetwas in irgendeiner Programmiersprache zu programmieren. Ich komme schon bei den Grundlagen der Syntax nicht weiter, haha!

@XanderBakker Ich hoffe, es macht dir nichts aus, dass ich dich erwähne! Ich habe gesehen, dass du hier eine offenbar ähnliche Lösung für das Problem vorgeschlagen hast. Ich dachte, vielleicht wärst du die richtige Person, die ich um Hilfe bitten könnte!

Hi @Anonymous User ,

I think you could use something like this:

// create a disctionary with field names and month names (change the field names!)
var dct = {"OpenJan": "January", "OpenFeb": "February",
           "OpenMar": "March", "OpenApr": "April", 
		   "OpenMay": "May", "OpenJun": "June",
		   "OpenJul": "July", "OpenAug": "August",
		   "OpenSep": "September", "OpenOct": "October",
		   "OpenNov": "November", "OpenDec": "December"};

// start with an empty result string
var result = "";

// loop through field names in dct
for (var fldname in dct) {
	// read the value of the field
	var fldval = $feature[fldname];
	// validate if the value is YES
	if (fldval == "YES") {
		// add the month to the result
		if (result == "") {
			// first month
			result = "Open in: " + dct[fldname];
		} else {
			// any next month
			result += ", " + dct[fldname];	
		}
	}
}

return result;	‍

Hi @Anonymous User ,

A simple fix could be this:

// create a disctionary with field names and month names (change the field names!)
var dct = {"OpenJan": "January", "OpenFeb": "February",
           "OpenMar": "March", "OpenApr": "April", 
		   "OpenMay": "May", "OpenJun": "June",
		   "OpenJul": "July", "OpenAug": "August",
		   "OpenSep": "September", "OpenOct": "October",
		   "OpenNov": "November", "OpenDec": "December"};

// simple fix, use a list of field names with the right order
var lst = ["OpenJan", "OpenFeb", "OpenMar", "OpenApr", 
		   "OpenMay", "OpenJun", "OpenJul", "OpenAug",
		   "OpenSep", "OpenOct", "OpenNov", "OpenDec"];

// start with an empty result string
var result = "OK";

// start with an empty result string
var result = "";

// loop through the list of field names
for (var i in lst) {
    var fldname = lst[i];
	// read the value of the field
	var fldval = $feature[fldname];
	// validate if the value is YES
	if (fldval == "YES") {
		// add the month to the result
		if (result == "") {
			// first month
			result = dct[fldname];
		} else {
			// any next month
			result += ", " + dct[fldname];	
		}
	}
}

return result;

You're a wizard! It worked perfectly besides listing a couple months in the wrong order, but I can manage fixing that myself I think.

One more piece of help please! It lists the months in alphabetical order instead of by the order of months in a year. I try and type some solutions to this into your code but I can't seem to do anything other than break it. What to do? @XanderBakker

Hi @Anonymous User ,

Glad to hear that it helped. If you run into problems with making the required changes just let me know.

About your questions:

For example, why use this method instead of creating an entire new feature?
- I wonder how you would create a new feature if you are not the owner of the data. You could with a notebook access the data, transform it the way you need it, and write a local feature layer and use that. This is more complex to implement.
What was the purpose of starting the logic part of the expression with "an empty results string?"
- Any variable you want to assign a value needs to be initialized. This is done using "var NameOfVariable = InitialValue". Perhaps this could be omitted and line 21 could start with "var ". However, sometimes this could create an error when compiling the code, so I prefer to initialize the variable before the loop.
Finally, what exactly do the "{" and "}" symbols do in this expression?
- The "{" and "}" are used to contain logic that needs to be executed. It also helps the readability of the code. To learn more about Arcade you could follow the learn path: https://learn.arcgis.com/en/paths/try-arcade/

Thanks for your explanations. I will be sure to explore the resources you linked to asap.

Hi @Anonymous User ,

Can you share the expression you have now?
