我是angularjs的新手,我正在尝试使用这篇文章中概述的样式:https://github.com/johnpapa/angular-styleguide。当使用var vm = this样式而不是$ scope时,我试图在模板中绑定的变量不可用。在控制台中检查vm会显示一个空对象,与$ scope不同。
/ * index.js * /
angular.module('myApp', ['ngAnimate', 'ngCookies', 'ngTouch', 'ngSanitize', 'ngResource', 'ngRoute', 'ui.bootstrap', 'loginModule', 'sidebarModule', 'jm.i18next'])
.value('baseUri', "/myApp/api")
.config(config)
.run(function($rootScope, $injector) {
$injector.get("$http").defaults.transformRequest = function(data, headersGetter) {
if ($rootScope.oauth !== undefined) {
console.log($rootScope.oauth);
headersGetter()['Access-Token'] = $rootScope.oauth.access_token;
}
if (data) {
return angular.toJson(data);
}
};
});
function config($routeProvider, $i18nextProvider) {
$routeProvider
.when('/', {
templateUrl: 'app/my-module-login/login.html',
controller: 'loginController',
conrollerAs: 'vm' // not available in template
})
.otherwise({
redirectTo: '/'
});
/ * login.module.js * /
angular.module('loginModule', ['utils']);
/ * login.controller.js * /
(function(){
'use strict';
angular.module('loginModule')
.controller('loginController', login);
login.$inject = ['$rootScope', '$scope', 'credsFactory', 'loginFactory'];
function login($rootScope, $scope, credsFactory, loginFactory) {
var vm = this; //empty object
vm.user = {};
vm.login = doLogin;
function doLogin(user) {
//user creds
var creds = {
userName: user.username,
password: user.password
};
loginFactory.login(creds)
.success(function (data) {
credsFactory.setCreds(data);
$scope.status = 'Logged in user!';
$scope.creds = creds;
var storageCreds = credsFactory.getCreds();
$rootScope.oauth = {};
$rootScope.oauth.access_token = storageCreds.accessToken;
window.location.hash = "#/logged-in";
}).
error(function(error) {
$scope.status = 'Unable to login user: ' + error.message;
});
}
}
})();
/ * login.html * /
<div class="form-group form-group-sm">
<div class="text-center">
<!-- how to access vm, {{vm.login(user)}} doesn't work -->
<button type="button" class="btn btn-default" id="login-submit" ng-i18next="button.cancel" ng-click="login(user)"></button>
</div>
</div>

您可以在设置路线时声明 controllerAs - 您的示例中存在拼写错误。 (名称不必与loginController函数中的名称相同)
路线:
$routeProvider
.when('/', {
templateUrl: 'app/my-module-login/login.html',
controller: 'loginController',
controllerAs: 'vm'
})
查看:
<button ng-click="vm.login(user)"></button>
另外,使用“var vm = this;”时在控制器功能中,您不需要注入$ scope。而不是doLogin成功函数中的$ scope:
vm.status = 'Logged in user!';
