在使用ArcGIS API For JavaScript开发web地图应用时，首先需要加载一个底图，大多时候我们使用官方提供的底图服务，该文介绍如何使用自定义底图以及多个底图之间的切换

一.多个官方底图切换

            margin: 0;
            padding: 0;
        }
        #map {
            padding: 0;
        }
    </style>
    <script>
        var map;
        require([
          "esri/map",

          "dojo/domReady!"
        ], function (
          Map,
          BasemapGallery,
          arcgisUtils,
          parser,
          Basemap,
          BasemapLayer
        ) {
            parser.parse();
            map = new Map("map", {
                basemap: "gray",
                center: [120.127653, 36.009423],
                zoom: 5
            });
            var basemapGallery = new BasemapGallery({
                showArcGISBasemaps: true,
                map: map
            }, "basemapGallery");
            basemapGallery.startup();
            basemapGallery.on("error", function (msg) {
                console.log("basemap gallery error:  ", msg);
            });
        });
    </script>
</head>

                    <div data-dojo-type="dijit/layout/ContentPane" style="width:380px; height:280px; overflow:auto;">
                        <div id="basemapGallery"></div>
                    </div>

二.自定义basemapGallery

除了引用官方的地图作为底图,也可以使用自己发布的底图服务作为BasemapGallery里面的底图，使用basemapgaller.add（）方法将自定义的底图加入；设置showArcGISBasemaps: false,可以隐藏官方的底图.
