Request: Stop using webmaps in samples

JeffPace — Wed, 02 Oct 2013 15:06:09 GMT

Wasn't sure where to put this.

The trend of using webmaps in

var mapDeferred = arcgisUtils.createMap("62702544d70648e593bc05d65180fd64", "map");

Is really frustrating as a developer. It hides so much code.

For example:
I looked at the LayerSwipe sample. Looks cool, I wonder what the overlay layers are and how to specify them. Open source code.

Oh.. its a webmap, cant see anything.

Oh well, can't use sample.

Is there anyway, that at least in the samples, everything can be manually defined?

Here's some code that shows working with the LayerSwipe without a web map. The only difference in this sample is that we add the layers to the map manually - working with the LayerSwipe stays the same. Was there a particular option on the LayerSwipe widget that you were trying to get to work?

    require([
      "esri/map", 
      "esri/dijit/LayerSwipe",
      "esri/layers/ArcGISDynamicMapServiceLayer",
      "esri/arcgis/utils",
      "dojo/_base/array",
      "dojo/domReady!"
    ], function(
      Map, LayerSwipe, ArcGISDynamicMapServiceLayer, arcgisUtils, array 
    )  {

      map = new Map("map", {
        basemap:"gray",
        center: [-96.5, 38.3],
        zoom: 6
      });
      
     var cities = new ArcGISDynamicMapServiceLayer("http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer"); 
     cities.setVisibleLayers([0]);
     var Hurricanes = new ArcGISDynamicMapServiceLayer("http://sampleserver6.arcgisonline.com/arcgis/rest/services/Hurricanes/MapServer");
     Hurricanes._div = map.root;
     cities._div = map.root;

     map.addLayers([Hurricanes, cities]);

    var swipeWidget = new LayerSwipe({
      type: "vertical",  //Try switching to "scope" or "horizontal"
      map: map,
      layers: [Hurricanes]
    }, "swipeDiv");

    swipeWidget.startup();  

    });
