How to debug javascript app errors?

I'm working through the KV-store tutorial and hit a snag ... which brought up the bigger question: how do I debug the calls being made from the Javascript UI to Splunk server?

In my case, I issue a 'service.del(...)' call against a KV-store, and the browser is showing no errors and refreshes the display -- but the key is never deleted.

(http://dev.splunk.com/view/SP-CAAAEZT ... on "step 5" of that tutorial ... I'm less concerned about my specific error and really asking how do you debug this in general)

( this is splunk-free running locally on a Mac, localhost:8000 connection so it isn't a network connectivity issue )

Now the problem is gone ... I did add an error handler to the service.del call (similar to what @poete recommended) but that error handler isn't called ... and the delete operation is working.

Hello @jbp4444,

I would start using the usual log display in the console (console.log(something).

If you open the console (F12 key for chrome), you will be able to see the output, and from there, debug your javascript code.
