禁用AngularJS上的日志记录

Question

I'm using in my code the angularJS service for logging ($log.error(), $log.debug(), $log.info(), etc) and it works fine.

Now, I'm trying to disable all the logs. I already tried this:

var app = angular.module('app', []);

app.config(
    ['$logProvider',
    function ($logProvider) {
        $logProvider.debugEnabled(false);
    }]
);

But this does nothing, the logs continues to show...

What is the best way to disable all the angularJS logs that I put in my code?

EDIT:

I'm calling the logs like this:

(function () {
    app.controller('MyController', ['$log',

            function($log) {
                 this.testFunction = function() {
                    $log.debug("debug");
                    $log.info("info");
                    $log.error("error");
                };

            }])
})();

You can "override" logging methods like below ( here full post ):

angular.module('app', [])

.config(['$provide', function ($provide) {
    $provide.decorator('$log', ['$delegate', function ($delegate) {
        // Keep track of the original debug method, we'll need it later.
        var origDebug = $delegate.debug;
        /*
         * Intercept the call to $log.debug() so we can add on 
         * our enhancement. We're going to add on a date and 
         * time stamp to the message that will be logged.
         */
        $delegate.debug = function () {
            var args = [].slice.call(arguments);
            args[0] = [new Date().toString(), ': ', args[0]].join('');

            // Send on our enhanced message to the original debug method.
            origDebug.apply(null, args)
        };

        return $delegate;
    }]);

Here is my two cents:

var IN_DEVELOPMENT = true;

$provide.decorator('$log', ['$delegate', function ($delegate)
{
        var originals = {};
        var methods = ['info' , 'debug' , 'warn' , 'error'];

        angular.forEach(methods , function(method)
        {
            originals[method] = $delegate[method];
            $delegate[method] = function()
            {
                if (IN_DEVELOPMENT) {
                    var args = [].slice.call(arguments);
                    var timestamp = new Date().toString();
                    args[0] = [timestamp.substring(4 , 24), ': ', args[0]].join('');
                    originals[method].apply(null , args);
                }
            };
       });

       return $delegate;
}]);

Just set boolean and done.

debugEnabled function should disable only $log.debug() messages. So if you want to disable logging with simple config as you have written, then rename all your debug calls to $log.debug , not to $log.log or $log.error or $log.info or $log.whatever .

You can see an example here http://jsfiddle.net/jccrosby/N2B6R/light/
