The debug method is not enabled by default because not all browsers support console.debug, but you can enable it in the configuration phase of your app with the $logProvider.
'use strict';
angular.module('analysis')
.config(function($logProvider){
$logProvider.debugEnabled(true);
})
.controller('AnalysisController', function(
$scope,
$timeout,
$mdSidenav,
$mdComponentRegistry,
$log,
Authentication
) {
$scope.user = Authentication.user;
// Option #1
//
// $scope.isOpen = function() { return $mdSidenav('right').isOpen(); };
// $scope.toggle = function() { $mdSidenav('right').toggle() };
// Option #2 - See https://github.com/angular/material/issues/974
$scope.toggle = angular.noop;
$scope.isOpen = function() {
return false;
};
$scope.toggleLeft = function() {
$mdSidenav('left').toggle().then(function() {
$log.debug('toggle left is done');
});
};
});
$log's debug method is disabled by default. You need to enable $log from app config phase like below.
app.config(function($logProvider){
$logProvider.debugEnabled(true);
});
仅供参考，当我无意中重新分配调试方法而不是调用它时，我遇到了同样的错误。
$log.debug = 'My log message'
而不是：
$log.debug('My log message')
浏览到包含错误语句的页面后，我会在其他包含日志语句的页面上获得"TypeError: $log.debug is not a function"。
