用于JavaScript的ArcGIS API是在web应用程序中嵌入地图和任务的轻量级方法。您可以从ArcGIS Online、您自己的ArcGIS Server或其他服务器获取这些地图。
（一）创建地图
描述
此示例演示如何创建一个完整的页面映射应用程序。此示例创建一个以旧金山市为中心的新地图，并将其中一个预定义的基本地图添加到地图中。
<!DOCTYPE html>
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"/><title>Simple Map</title><link rel="stylesheet" href="https://js.arcgis.com/3.44/esri/css/esri.css"><style>html, body, #map {height: 100%;margin: 0;padding: 0;}</style><script src="https://js.arcgis.com/3.44/"></script><script>var map;require(["esri/map", "dojo/domReady!"], function(Map) {map = new Map("map", {basemap: "topo-vector", //For full list of pre-defined basemaps, navigate to http://arcg.is/1JVo6Wdcenter: [-122.45, 37.75], // longitude, latitudezoom: 13});});</script></head><body><div id="map"></div></body>
</html>
（二）基准图库
描述
使用BasemapGallery小部件可以选择地图的基础地图。这个小部件提供了一个基本地图库，这些地图可以由用户定义，也可以由ArcGIS.com的查询生成。
您可以向库中添加其他基础地图，但是添加到基础地图库中的所有基础地图必须位于同一投影中。如果您正在通过设置从ArcGIS.com显示棒球地图
showArcGISBasemaps = true
那么附加的基本地图必须在Web-Mercator投影中

（三）编辑书签
描述
书签小部件可以配置为允许用户创建、更新和删除书签。
<!DOCTYPE html>
<html><head><meta charset="utf-8"><meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"><title>Bookmark Widget (Editable)</title><link rel="stylesheet" href="https://js.arcgis.com/3.44/esri/themes/calcite/dijit/calcite.css"><link rel="stylesheet" href="https://js.arcgis.com/3.44/esri/themes/calcite/esri/esri.css"><style>html, body, #map {height: 100%;margin: 0;padding: 0;}.bookmark-container {position: absolute;top: 100px;left: 15px;padding: 1rem;background: #ffffff;border-radius: 4px;border: 1px solid #eeeeee;}</style><script src="https://js.arcgis.com/3.44/"></script><script>require(["esri/map","esri/dijit/Bookmarks","dojo/domReady!"],function (Map, Bookmarks){var map = new Map("map", {basemap: "topo-vector",center: [-100, 40],zoom: 4});// Create the bookmark widget// specify "editable" as true to enable editingvar bookmarks = new Bookmarks({map: map,bookmarks: [],editable: true}, "bookmarks");// Bookmark data objectsvar bookmarkJSON = {first: {"extent": {"xmin": -12975100,"ymin": 3993900,"xmax": -12964100,"ymax": 4019500,"spatialReference": {"wkid": 102100,"latestWkid": 3857}},"name": "Palm Springs, CA"},second: {"extent": {"xmin": -13052100,"ymin": 4024900,"xmax": -13041100,"ymax": 4050500,"spatialReference": {"wkid": 102100,"latestWkid": 3857}},"name": "Redlands, California"},third: {"extent": {"xmin": -13048800,"ymin": 3844800,"xmax": -13037800,"ymax": 3870400,"spatialReference": {"wkid": 102100,"latestWkid": 3857}},"name": "San Diego, CA"},};// Add bookmarks to the widgetObject.keys(bookmarkJSON).forEach(function (bookmark){bookmarks.addBookmark(bookmarkJSON[bookmark]);});});</script></head><body class="calcite"><div id="map"></div><div class="bookmark-container"><div id="bookmarks"></div></div></body>
</html>
（四）主页按钮
描述
使用HomeButton小部件快速返回到地图的默认起始范围。创建小部件时，开发人员指定一个将用作“主扩展区”的扩展区。当用户在地图上平移和缩放时，他们可以单击主页按钮返回到指定的起始范围。
<!DOCTYPE HTML>

（六）测量小工具
描述
此示例显示如何将Measurement小部件添加到应用程序中。2.3版新增的Measurement小部件提供了用于确定x、y位置以及测量区域和距离的工具。此示例显示如何创建新的Measurement小部件并将其与地图关联。
（可选）您可以定义自定义线和点符号，测量小部件在地图上绘制时将使用该符号。启用捕捉后，测量工具将执行此操作并捕捉到地图中的要素。

（七）概览图
描述
使用OverviewMap小部件在主地图的右上角显示一个小地图。
<!DOCTYPE html>
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"><title>Overview Map</title><link rel="stylesheet" href="https://js.arcgis.com/3.44/dijit/themes/claro/claro.css"><link rel="stylesheet" href="https://js.arcgis.com/3.44/esri/css/esri.css"><style>html, body { height: 100%; width: 100%; margin: 0; padding: 0; }</style><script src="https://js.arcgis.com/3.44/"></script><script>var map;require(["esri/map", "esri/dijit/OverviewMap","dojo/parser","dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"], function (Map, OverviewMap,parser) {parser.parse();map = new Map("map", {basemap: "satellite",center: [-122.445, 37.752],zoom: 14});var overviewMapDijit = new OverviewMap({map: map,visible: true});overviewMapDijit.startup();});</script></head><body class="claro"><div data-dojo-type="dijit/layout/BorderContainer"data-dojo-props="design:'headline', gutters:false"style="width: 100%; height: 100%; margin:0;"><div id="map"data-dojo-type="dijit/layout/ContentPane"data-dojo-props="region:'center'"style="padding:0"></div></div></body>
</html>
（八）比例尺
描述
此示例显示如何将比例尺添加到地图中。比例尺可以添加到地图或用户指定的位置。下面的代码显示了显示在地图左下角的默认比例尺。您可以通过将attachTo选项设置为以下值之一来修改比例尺的位置：右上角、右下角、上中心、下中心、左下角、左上角。

</html>
（九）要素图层（基本）
描述
此示例演示如何将基本要素图层添加到地图中。FeatureLayer至少必须指向ArcGIS Server或ArcGIS Online上托管的有效要素服务，或者使用要素集合对象构建。要了解有关功能服务的更多信息，请阅读本文档。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no">
<title>FeatureLayer</title><link rel="stylesheet" href="https://js.arcgis.com/3.44/esri/css/esri.css">
<script src="https://js.arcgis.com/3.44/"></script><style>
html, body, #map {padding: 0;margin: 0;height: 100%;width: 100%;
}
</style><script>
require(["esri/map","esri/layers/FeatureLayer","dojo/domReady!"],function(Map,FeatureLayer) {var map = new Map("map", {basemap: "hybrid",center: [-82.44109, 35.6122],zoom: 17});/***************************************************************** Add feature layer - A FeatureLayer at minimum should point* to a URL to a feature service or point to a feature collection * object.***************************************************************/// Carbon storage of trees in Warren Wilson College.var featureLayer = new FeatureLayer("https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Landscape_Trees/FeatureServer/0");map.addLayer(featureLayer);});
</script>
</head><body><div id="map"></div>
</body></html>
（十）向地图添加图形
描述
可以使用“绘制”工具栏在地图上绘制形状。
工具栏不是您在页面上自动看到的用户界面组件。相反，它是一个辅助类，可以用来让人们在地图上绘制几何图形。它省去了编写用于绘制每种几何图形类型的代码的工作量。您只需激活希望人们绘制的几何图形类型。在本例中，每个按钮都会激活不同的几何图形类型。
单击按钮时，工具栏将激活相应的工具。或者，您可以允许从下拉列表、一组单选按钮或其他控件中选择几何图形类型。
当工具栏的“draw-end”事件触发时，将调用一个函数，以确保在绘制完要素后在地图上看到某些内容。addGraphic函数为几何图形类型设置适当的符号。有关符号，请参阅API参考，以了解有关定义不同符号的更多信息。
