ArcGIS API for JavaScript ^3.29

• In this example, a new map named "map" is created and will be placed inside a container named "mapDiv".
  

  require([
    "esri/map", ... 
  ], function(Map, ... ) {
    var map = new Map("mapDiv");
    ...
  });
  

  Later in the code, the map container is referenced in the DIV id.
  

  <div id="mapDiv" style="width:600px; height:600px; border:1px solid #000;"></div>
  

• In this second example, the optional extent parameter is also included in the constructor.
  

  require([
    "esri/map", "esri/geometry/Extent", ... 
  ], function(Map, Extent, ... ) {
    var map = new Map("mapDiv", { extent: new Extent(-124.71, 31.89, -113.97, 42.63) });
    ...
  });
  

• This example creates a map with no slider or pan arrows.

  require([
    "esri/map", ... 
  ], function(Map, ... ) {
    var map = new Map("mapDiv", { slider:false, nav:false });
    ...
  });
  

• In this example, graphics are turned off whenever the map is panned.

  require([
    "esri/map", ... 
  ], function(Map, ... ) {
    var map = new Map("mapDiv", { displayGraphicsOnPan:false });
    ...
  });
  

  
  If you want the graphics turned off during a pan only for Internet Explorer, use the following constructor:

  require([
    "esri/map", ... 
  ], function(Map, ... ) {
    var map = new Map("mapDiv", { displayGraphicsOnPan:! dojo.isIE });
    ...
  });
  

function showExtent() {

  var s = "";

  s = "XMin: "+ map.extent.xmin

      +" YMin: " + map.extent.ymin

      +" XMax: " + map.extent.xmax

      +" YMax: " + map.extent.ymax;

      dojo.byId("info").innerHTML = s;

}

require(["esri/map"], function(Map) {
  var map = new Map( ... );
  map.on("extent-change", function(){
    var geo = map.geographicExtent;
    console.log(geo.xmin, geo.ymin, geo.xmax, geo.ymax);
  });
  ...
});

require([

  var map = new Map( ... );
  map.on("load", function() { ShowLocation(-81.3765, 28.54175); });

  function ShowLocation(x, y) {
    var point = new Point(x, y, new SpatialReference({wkid:4326}));

    var graphic = new Graphic(point, simpleMarkerSymbol);

    map.graphics.add(graphic);
