Expresión Arcade para decodificar valores

AndrewL

<\/HEAD>

Estoy intentando usar una expresión Arcade para mostrar valores codificados en un popup en ArcGIS Online, pero no funciona. Estoy usando el código del ejemplo de decode<\/A>. No se muestra en el popup. No aparece ningún mensaje de error en el popup.<\/P>

<\/P>

var code = $feature.dn;
var decodedValue = Decode(code, 2, 'No Severo', 3, 'Marginal', 4, 'Leve', 'Otro');<\/P>

<\/P>

No soy el autor del servicio de mapas. El campo dn es un esriFieldTypeDouble.<\/EM> Gracias.<\/P><\/P><\/EM><\/P><\/BODY><\/HTML>

You needed to state what value to return. See the documentation about this.

<SPAN class="keyword token">var</SPAN> code <SPAN class="operator token">=</SPAN> $feature<SPAN class="punctuation token">.</SPAN>dn<SPAN class="punctuation token">;</SPAN>

or it could be a single line expression.
