1. Add Two Dynamic Layers(添加两个动态图层)

Description

Add two dynamic map services to a map and use the setInfoTemplates method to specify what information should be shown when a feature from a map service is clicked.

向地图添加两个动态地图服务，并使用setInfoTemplates方法指定单击地图服务中的某个功能时应显示哪些信息。

dynamicLayer和一般的Layer的区别是？好像现在的mapserver都是dynamiclayer了。。不用设置。。以前的mapserver好像是需要设置是否可以动态的更改。而现在不用。但是这种设置是临时的，不会修改服务器端的默认配置 [Wrong!也是需要设置的]试验：https://blog.csdn.net/nmj2008/article/details/115000401

dynamicLayer的好处：https://blog.csdn.net/u012123612/article/details/53641234用于动态变化的图层，它的好处在于不需要发布地图？？？这是在ArcGIS Server10.1版本之后，ArcGIS Server才提供的一种新的功能：动态图层。准确的说，动态图层并不是一种新的地图服务，它更像是地图服务（MapServer）的一种扩展。不需要将shp文件发布为服务，服务器可以直接读取shp文件在前端显示，实现拓展。既然知道动态图层并不是一种新的服务类型，而是地图服务的一种扩展，因此我们不需要发布服务，只需要对地图服务添加动态图层功能即可。启用地图服务的步骤为：。。。但是我使用动态图层的目的并不是为了扩展现有的服务。。而是。。。修改原有图层的属性或者样式。

2. Change attribute used for a renderer(更改用于渲染器的属性)

Description

This functionality requires an ArcGIS Server 10.1 service.

Dynamic layers provide the ability to change the renderer(s) for layers in a dynamic map service. In this sample, a drop-down list is populated with attribute field names for a layer that is displayed on the map using an ArcGIS Server 10.1 dynamic layer and a dynamic map service layer. When the selected field changes, a new map image is requested using the new field as the basis for the layer's renderer.

动态图层提供更改动态地图服务中图层的渲染器的功能。在此示例中，下拉列表中填充了使用ArcGIS Server 10.1动态图层和动态地图服务图层在地图上显示的图层的属性字段名称。当选定字段更改时，将使用新字段作为层渲染器的基础来请求新的地图图像。
