"Summarize" The map class of the ArcGIS JS API

ArcGis for Javascrept_esri_map class:

　　1. Construction method: Esri. Map ();

Parameters:

Extent	If this option is set, once the projection of this option is set, all the layers are drawn in the defined projection.
Logo	Whether to display ESRI's logo.
wrapAround180	Whether to move the map continuously (that is, by date Line, similar to horizontal rotation of the map 360 degrees).
LODs	Sets the initial scale level of the map.
Maxscale	Set the maximum visual scale for a map
Sliderstyle	Sets the style of the slider (the value is large or small

Cases:

1 startextent = new Esri.geometry.Extent (119.9299, 30.1652, 120.3687, 30.4028,//These four parameters are the maximum and minimum latitude and longitude of 2         new ESRI. Spatialreference ({wkid:4490}),//This parameter defines the coordinate system of map 3); 4 Esri.config.defaults.map.sliderLabel = null;5 Map = New ESRI. Map (' MyMap ', {6         logo:false,7         slider:false,8         extent:startextent,9});
