CSV File will not display points anymore in the JavaScript api?

[KeriLu]

Hmmm....not sure what's going on here. I used to be able to grab my csv file from our server and do and xy events so the point shows up on the webmap made with the Javascript Api but I can't seem to do that anymore. I have been reading the discussion forums and a few suggestions mention setting up a proxy server. I ran the .jsp file but I am not really sure how to proceed? Doen't seem to make a difference. My csv file simply doesn's show up as points on my map anymore. I do not clearly understand the process of registering an app on the ArcGIS for Developers site either? Can someone please help me clarify?

Thanks!!

When you run your app have you checked the browsers developer console to see if there are any error messages?

[KeriLu]

I do not know how to check the browser's developer console. I used to be able to run this simple code CSV | ArcGIS API for JavaScript  but I can't even do that anymore.

Keri which browser are you using for testing?

[KeriLu]

The code only works in the sandbox environment.

Keri,

Here is info on how to open the developer tools for Chrome. Once you have them open click on console then re-run your app and see if any error messages appear.

Do you have a proxy setup locally? Because the csv data used in the sample is not on the same domain as your web site you'll need to setup a proxy. Details on setting up a proxy can be found here:

Esri/resource-proxy · GitHub

If you want to test to see if this is a proxy issue you can download a copy of the csv and host it on your web server. http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_week.csv

Ok. Thanks.

Those are the error messages I am getting.

Keri,

It looks like you are running the code from file:// instead of from a web server. You'll want to setup a web server and test the samples there. More info on how to do this can be found here:
