ArcGIS JavaScript API 实现基本的地图功能

代码如下:

<!DOCTYPE html>
<html>
<head>
    <title>创建一幅地图</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

        html, body, #mapDiv{

        var map,lods,fullExtent,tiledMapServiceLayer;
        require(["esri/map", "esri/geometry/Extent", "esri/layers/ArcGISTiledMapServiceLayer", "dojo/domReady!"], function(Map, Extent, ArcGISTiledMapServiceLayer) {
            lods = [
