Question

我正在尝试在登录控件中写入空闲超时问题，但是却无法读取未定义的属性'watch'。

我正在尝试在Tomcat Server 7和Angular 1.5中执行以下代码

$scope.started = false;

function closeModals() {

    alert(1);
    if ($scope.warning) {
        $scope.warning.close();
        $scope.warning = null;
    }

    if ($scope.timedout) {
        $scope.timedout.close();
        $scope.timedout = null;
    }
}

$scope.$on('IdleStart', function() {
    closeModals();

    $scope.warning = $modal.open({
        templateUrl: 'warning-dialog.html',
        windowClass: 'modal-warning'
    });
});

$scope.$on('IdleEnd', function() {
    closeModals();
});

$scope.$on('IdleTimeout', function() {
    closeModals();
    $scope.timedout = $modal.open({
        templateUrl: 'timedout-dialog.html',
        windowClass: 'modal-danger'
    });
});

$scope.start = function() {
    console.log('start');
    closeModals();
    Idle.watch();
    $scope.started = true;
    alert("Hi")
};

$scope.stop = function() {
    console.log('stop');
    closeModals();
    Idle.unwatch();
    $scope.started = false;
};

nuncasApp.config(function(IdleProvider, KeepaliveProvider) {
    alert(3);
    IdleProvider.idle(5);
    IdleProvider.timeout(5);
    KeepaliveProvider.interval(10);
    IdleProvider.interrupt('keydown wheel mousedown touchstart touchmove scroll');
});

我从https://jsfiddle.net/esoyke/fkqLqy7c/获得了代码。

我收到以下错误：

angular.js:13920 TypeError: Cannot read property 'watch' of undefined at b.$scope.start (loginCtrl.js:141)

请确认您已正确注入此依赖项，如var myApp = angular.module("myApp", ['ngIdle'])和app.controller('DemoCtrl', function($scope, Idle /*other injections*/)中一样。

TypeError：无法读取angularjs ng-idle中未定义的属性“ watch”？
