0.引言
ArcGIS For JS 是一种用于创建和编辑地理信息的 JavaScript 库，它允许用户在线编辑 ArcGIS Server 发布的几何要素。本文从ArcGIS创建几何要素、编辑要素，然后发布要素到ArcGIS Server，最后由ArcgisForJS访问A如此GIS Server发布的几何要素。
1.ArcGIS创建几何要素
（1）新建一个mxd地图文档，命名geoedit。
（2）新建点、线、面要素
创建要素时，添加字段，名称：va，类型：文本。
创建结果如下：
（3）注册要素
（4）编辑点、线、面要素
设置各要素的值，以下以点为例：
再设置线要素和面要素的va值。
（5）设置点、线、面样式
（6）可以保存要素为模板
2.ArcGIS Server发布几何要素
在ArcGIS Server中查看发布的几何要素。
REST URL：http://localhost:6080/arcgis/rest/services/geoedit/FeatureServer
3.ArcgisForJS在线编辑ArcGIS Server发布的几何要素
（1）实现代码

</head> <body> <div id="viewDiv"></div>
</body> </html>
