How to Add A Layer?

EricBianchi1 — Sat, 09 Apr 2016 20:30:33 GMT

Hello,

So I am in the process of making a map that has interactive capabilities and operates through a website. Right now I have the website, and the esri base map (open streets) is all that is on there. The website is essentially just the map. I am using the arcGIS javascript to upload the map and the coordinates and extents etc. A screen-shot is shown below.

I need help with adding my layer to the map. The layer is compatible with arcGIS and esri, and I can add it the map editor, as you can see here... The rest endpoint data was obtained through a link.

->How do I add this layer to my web map?

Thank you for taking time to read my query, and I appreciate any insight, help, instructions, or links that may help in my pursuit to make this work.

Bonus question:

*** I want the user to be able to filter the data, is there a way to make certain kind of buttons that have a predetermined filtering function, that would filter multiple things at once. Say we have a visitor, and they want to see only spots visitors could park, I want them to be able to press 1 button and have the map filter in a way that has been predetermined. So how can I get these filter options to show up on the map?

Hi Eric,

Have you gone through the sample JavaScript code here:

Feature Layer (basic) | ArcGIS API for JavaScript

This may help answer the first part of your post.

There is some code regarding to filtering here:

Thanks for your response,

I just so happened to find that same link in my search today.

So yes, I have tried, here is my code.

It doesn't seem to want to add my layer.. or am I missing something?

Hmm, do you get an error or anything? Have you tried playing around in the Sandbox and changing some variables here and there to make it work?

Adrian,

I was able to get the layer to work after some research.

Thanks for all your help, you definitely kept me in the right direction.

I am glad some of that was helpful! If you can, can you post your final code to show how you get it to work?

Thanks!
