Part 2：CSS

html, body, #viewDiv01 {padding: 0;margin: 0;height: 100%;width: 100%;}#popdiv_write{position: absolute;top: 10px;right: 10px;width: 140px;height: 93%;padding: 5px;background-size: 100%;background-color: #C0C0C0;opacity: 0.8;z-index: 9;border: 3px dashed #000000;border-radius:5px ;}.basemap{margin: 10px;z-index: 20;}

Part 3：Javascript

require(["esri/Map","esri/views/MapView"], function(Map, MapView) {//**********************************************功能1：切换地图的底图**********************************************************var map01 = new Map({basemap: "streets"});var view = new MapView({container: "viewDiv01",map: map01,center: [-118.71511,34.09042],zoom: 11});document.getElementById("basemap01").addEventListener("click",function(){map01.basemap= "gray";});document.getElementById("basemap02").addEventListener("click",function(){map01.basemap= "hybrid";});document.getElementById("basemap03").addEventListener("click",function(){map01.basemap= "national-geographic";});document.getElementById("basemap04").addEventListener("click",function(){map01.basemap= "osm";});document.getElementById("basemap05").addEventListener("click",function(){map01.basemap= "streets";});//**********************************************功能：显示地图的比例尺，鼠标等坐标点等**********************************************************//*** 添加DIV用于显示坐标等信息 ***//var coordsWidget = document.createElement("div");coordsWidget.id = "coordsWidget";coordsWidget.className = "esri-widget esri-component";coordsWidget.style.padding = "7px 15px 5px";view.ui.add(coordsWidget, "bottom-left");//***显示经纬度、比例尺大小和尺度***//function showCoordinates(pt) {var coords = "Lat/Lon " + pt.latitude.toFixed(3) + " " + pt.longitude.toFixed(3) + " | Scale 1:" + Math.round(view.scale * 1) / 1 +" | Zoom " + view.zoom;coordsWidget.innerHTML = coords;}//*** 添加事件显示中心的坐标（在视图停止移动之后） ***//view.watch(["stationary"], function() {showCoordinates(view.center);});//*** 添加显示鼠标的坐标点***//view.on(["pointer-down","pointer-move"], function(evt) {showCoordinates(view.toMap({ x: evt.x, y: evt.y }));});});
