Legend widget for tiled map service

JohnFell — Sat, 11 Dec 2021 06:16:11 GMT

Does anyone have an example for the legend widget using a tiled map service?

When I try to load the legend using our tiled map service I don't see the map service initially nor does the legend display. Please help. See code below.

      require(["esri/map", "esri/layers/ArcGISTiledMapServiceLayer", "dojo/domReady!", "esri/dijit/Legend"],
        function(Map, ArcGISTiledMapServiceLayer, Legend) {
          map = new Map("map", [{center: [ -96.851, 32.807 ]}]);
          


          var tiled = new ArcGISTiledMapServiceLayer("https://maps.dcad.org/prdwa/rest/services/Property/PropMap/MapServer");          
          map.addLayer(tiled);
          
          map.on("load", function(evt){
            var legend = new Legend({
              map: map,
            }, "legendDiv");
              
            legend.startup(); 
          });
        }
      );

The arguments in your function don't match the modules in the require statement. If you change it to this, it works properly.

require(["esri/map", "esri/layers/ArcGISTiledMapServiceLayer", "esri/dijit/Legend", "dojo/domReady!"],
    function(Map, ArcGISTiledMapServiceLayer, Legend) {‍‍‍‍
