In fact, there are two examples of ArcGIS API for JavaScript, but there are some parameters that are not clearly explained. An example of ArcGIS is a service published by GeoServer as an example, and here is an independent Geowebcache service WMTS service, the address is HTTP://LOCALHOST:8080/GEOWEBCACHE/SERVICE/WMTS, The example given by ArcGIS has not been tuned for two days, as in the following example (
Mouse events on maps and graphics(Mouse events on map and graphics, specifically those on map and graphiclayer)
The ArcGIS javascript API map and graphics layer provide a large set of MouseEvents users can use to interact with these objects(ArcGIS javascript API map and graphiclayer provide a large number of mouse ev

One, what is DOM?
What do you mean Dom,dom is the Document Object model, a set of API interfaces that are based on browser programming (in this tutorial, DHTML programming), the recommended standards for the Web, and each browser has some subtle differences, One of Mozilla's browsers is closest to the standard. Simple JavaScript can be used to make DHTML programming with DOM in order to make a beautiful eff
