1、引用gis的css样式和js文件

@*gis的css*@
<link href="http://11.101.9.53/arcgis_js_v39_sdk/arcgis_js_api/library/3.9/3.9/js/dojo/dijit/themes/claro/claro.css" rel="stylesheet" />
<link href="http://11.101.9.53/arcgis_js_v39_sdk/arcgis_js_api/library/3.9/3.9/js/esri/css/esri.css" rel="stylesheet" />

@*gis的js*@
<script src="http://11.101.9.53/arcgis_js_v39_sdk/arcgis_js_api/library/3.9/3.9/init.js"></script>
<script src="/Static/js/gis.js"></script>

2、

var GISSERVERURL = "http://11.101.9.53:6080/";// 定义地图的服务器地址
var map;// 定义地图容器
var locationPoint;// 定义定位地图的方法

// 加载地图引用
