how to see phonegap javascript log messages on xco

Question

I am trying to develop a basic hello world application with phonegap on Xcode. But i can not see the log messages on Xcode console. I have tried console.log and debug.log but they did not worked for me?

How can i see javascript log messages on xcode console?

Answer 1

In Phonegap 3.0 you have to add a plugin for console.log to work in the xcode console.

$ phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-console.git

More info: http://docs.phonegap.com/en/edge/guide_cli_index.md.html#The%20Command-line%20Interface

Answer 2

console.log("msg here: "+var); should work. It will come out as ...[INFO] msg here: hi! (after the date, time, app, etc.).

To view the messages go to View > Debug Area > Activate Console (or shift+cmd+C)

Answer 3

1. Add the Debug console plugin
2. Add a console.log message in onDeviceReady in the sample phonegap code or code that runs after that.

Important: console messages are displayed after the 'deviceready' event. Console.log will not generate message before that.

Answer 4

Phonegap has a pretty good blog post about this here.

One of the things they mention includes JSLint which I personally use a decent amount. You just post your JS code there and it'll scan for errors and good styling. I also suggest trying to put t the code in a simple html file and run it on the browser. Anything that might seem phone-related, just get rid of it. Its nice to sandbox your javascript on the browser side and then use things like Firebug or Chrome's debugger. (Also I'm sure console.log() will work there :D)

I've also seen a lot of people mention, including in the blog post, about Weinre so that is something worth checking out.

Answer 5

confirm("msg here: "+var);

or

console.log("msg here: "+var);

Answer 6

As @NickBreen said, you must add the right plugin, but we also needed to wait for the deviceready event to fire before the console displayed log statements.
