提问by Volatil3
I am getting undefinedfor $routeParams. Here is my code:
我得到undefined了 $routeParams。这是我的代码：
var ngAddressBook = angular.module('ngAddressBook', ['ngRoute']);
ngAddressBook.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'views/list.html',
controller: 'ngAddressListController'
}).
when('/add', {
templateUrl: 'views/add.html',
controller: 'ngAddressListController'
}).
when('/details/:id', {
templateUrl: 'views/details.html',
controller: 'ngAddressDetailsController'
});
}]);
// add a controller to it
ngAddressBook.controller('ngAddressListController', ['$scope', function ($scope)
{
$scope.contacts = [
{id:1,first_name:'Jane', last_name:'Doe','Phone':'123-456789','Email':'[email protected]'},
{id:2,first_name:'Jhon', last_name:'Doe','Phone':'123-456789','Email':'[email protected]'}
];
$scope.getTotalContacts = function () {
return $scope.contacts.length;
};
}]);
ngAddressBook.controller('ngAddressDetailsController', ['$scope', function ($scope,$routeParams)
{
alert($routeParams);
$scope.id = $routeParams.id;
}]);

There is a problem in controller parameter injection. You have not added $routeParamsin your array injection list.
控制器参数注入有问题。您尚未添加$routeParams到阵列注入列表中。
ngAddressBook.controller('ngAddressDetailsController', ['$scope','$routeParams', function ($scope,$routeParams)
{
alert($routeParams);
$scope.id = $routeParams.id;
}]);

As I found this on top on google:
apart from the missing injection - asign the object $routeParamsand not the Key $routeParams.id
正如我在谷歌上发现的那样：除了丢失的注入 - 分配对象$routeParams而不是密钥$routeParams.id
I found the explination here (from Sander Elias)
ngAddressBook.controller('ngAddressDetailsController', ['$scope','$routeParams', function ($scope,$routeParams)
{
$scope.id = $routeParams
alert($routeParams);
}]);
