I have a problem related to "ArcGISTiledMapServiceLayer". I have an ArcGISTiledMapServiceLayer map service, which I have added to Map object. This service work as BaseMap. Now I want to add another ArcGISTiledMapServiceLayer map service layer to the same Map object. Before adding the new layer, I just removed the previous tiled map service layer by using method objMap.removeAllLayers(). But this method only removes the layer not the extent and it create problem when I add a new layer.

So I want to remove completely the ArcGISTiledMapServiceLayer (layer, extent, scale etc.).

I have tried all the below methods

  1. objMap.removeAllLayers();

  2. objMap.removeLayer(objMap.getLayer('myLayerID'));

Any solution?

  • After removing first layer, when I add second layer, the map not get zoom after zoom level 5. – Sanjay Gupta Jul 28 '14 at 7:02

    @StephenLead: My comment seems to be no longer corrrect. In the 1.x & 2.x version of the API you could change the projection & lods after setting it. It does not seem to be possible in the 3.x version. Hence the answer given by janechii seems to be the best way to do this. – Devdatta Tengshe Aug 28 '14 at 2:40
  • @StephenLead: you are right. I've deleted my comments. – Devdatta Tengshe Aug 28 '14 at 6:09
  • @DevdattaTengshe thanks for elaborating. I've never worked with pre v3 versions, so it's good to make this distinction! – janechii Aug 28 '14 at 20:39

You should be able to call destroy on the current map instance then create a new esri/Map instance and load the new base map.

See: https://developers.arcgis.com/javascript/jsapi/map-amd.html#destroy

var map1 = new Map('map');
var basemap1 = new ArcGISTiledMapServiceLayer(url);
map1.addLayer(basemap1);
...
map1.destroy();
...
var map2 = new Map('map'); // note we load to the same html node
var basemap2 = new ArcGISTiledMapServiceLayer(url);
map2.addLayer(basemap2);
