Question sur la carte ESRI

Question

Je suis nouveau dans les cartes ESRI, et je cherche à créer une carte en utilisant javascript où les utilisateurs peuvent cliquer pour sélectionner des points, des polygones ou des segments de ligne. J'apprécierais des conseils sur la meilleure méthode et tout code d'exemple que vous pourriez partager.<\/P> Merci<\/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.
