  • ArcGIS api for js OverviewMap(鹰眼/概览图)

    说明、本篇博客中主要介绍 地图显示在某个div情况

    1、运行效果

    2、HTML

    <!DOCTYPE html>

        <script>
            var dojoConfig = {
                parseOnLoad: true
            };
        </script>
        <script type="text/Javascript" src="http://localhost/arcgis_js3_api/library/3.3/jsapi/init.js"></script>
        <script>
            // 导入必要包
            dojo.require("dijit.layout.BorderContainer");
            dojo.require("dijit.layout.ContentPane");
            dojo.require("esri.map");
            dojo.require("esri.dijit.OverviewMap");
            var map;
    
            function init() {
                map = new esri.Map("map", {
                    basemap: "topo", // 指定的地图底图.有效选项:"streets","satellite","hybrid","topo","gray","oceans","national-geographic","osm".
                    center: [-122.445, 37.752],    // 居中的经纬度
                    zoom: 14    // 缩放深度级别
                });
    
                dojo.connect(map, "onLoad", function (theMap) {
                    // 添加概览地图
                    var overviewMapDijit = new esri.dijit.OverviewMap({
                        map: map,    // 必要的
                        visible: true,    // 初始化可见,默认为false
                        attachTo: "bottom-right",    // 默认右上角
                         150,    // 默认值是地图高度的 1/4th
                        height: 150, // 默认值是地图高度的 1/4th 
                        opacity: .40,     // 透明度    默认0.5
                        maximizeButton: true,    // 最大化,最小化按钮,默认false
                        expandFactor: 3,    //概览地图和总览图上显示的程度矩形的大小之间的比例。默认值是2,这意味着概览地图将至少是两倍的大小的程度矩形。
                        color: "red"    // 默认颜色为#000000
                    });
                    overviewMapDijit.startup();    // 开启
                });
            }
    
            dojo.ready(init);
        </script>
      </head>
      
      <body class="claro">
        <div style="700px;height:600px;">
            <div data-dojo-type="dijit.layout.BorderContainer" 
             data-dojo-props="design:'headline', gutters:false" 
             style=" 100%; height: 100%; margin:0;">
     
          <div id="map" 
               data-dojo-type="dijit.layout.ContentPane" 
               data-dojo-props="region:'center'" 
               style="padding:0">
          </div>
        </div>
        </div>
      </body>
    
    </html>

    其中代码

         map = new esri.Map("map", {
                    basemap: "topo", // 指定的地图底图.有效选项:"streets","satellite","hybrid","topo","gray","oceans","national-geographic","osm".
                    center: [-122.445, 37.752],    // 居中的经纬度
                    zoom: 14    // 缩放深度级别
                });
    

     还可以替换为下面这种形式

    map = new esri.Map("map", { center: [-122.445, 37.752], zoom: 4 });
    MyTiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer
    ("http://localhost/arcgis/rest/services/DZDT2012/MapServer");
    map.addLayer(MyTiledMapServiceLayer);

    注意:直接拷贝代码的时候 要把引用文件的

    arcgis_js3_api修改为
    arcgis_js_api
    例如:
     <link rel="stylesheet" type="text/css" href="http://localhost/arcgis_js3_api/library/3.3/jsapi/js/dojo/dijit/themes/claro/claro.css"/>修改为
    <link rel="stylesheet" type="text/css" href="http://localhost/arcgis_js_api/library/3.3/jsapi/js/dojo/dijit/themes/claro/claro.css"/>
    因为我本机IIS文件夹名称是
    arcgis_js3_api
