ESRI Map Frage

Question

Ich bin neu bei ESRI maps und möchte eine Karte mit javascript erstellen, bei der Benutzer Punkte, Polygone oder Liniensegmente anklicken können, um sie auszuwählen. Ich würde mich über Hinweise zur besten Methode und Beispielcodes freuen, die Sie teilen können.<\/P> Vielen Dank<\/P>

Using Map Viewer point, polygon, and line layers can be added individually. Depending on what you want to do, those layers can remain individual layers or you can add them to a group layer. The choice is yours, and the decision will really be based upon what works best for you. Often the streets are just part of the basemap you choose to use, unless you are doing something specifically with the streets or streets that are different than what appears in basemaps.

Thank you for the reply.

How to get polygon, points and streets together on the map? Do you need to create a group layers using adding feature layer service?

thanks

Just something to keep in mind - you can always author the web map using Map Viewer and reference it in your JavaScript code. Saves you a lot of code and time, IMHO.
