控制器启动两次

Question

我有一个简单的控制器 (logincontroller)，它在加载时启动两次 login.html，但我不知道为什么会这样。

MyApp.js:

angular.module('PVM', [
    'Authentication',
    'Modal',
    'ngRoute'
])
.config([
    '$routeProvider', function($routeProvider) {
        $routeProvider
            .when('/Login', {
                controller: 'LoginController',
                templateUrl: 'Login.html'
            })
            .when('/Home', {
                controller: 'ModalController',
                templateUrl: 'Home.html'
            })
            .otherwise({
                redirectTo: '/Login'
            });
    }
]);

LoginController.js:

angular.module("Authentication")
.controller("LoginController",
[
    "$scope", "$rootScope", "$location", "AuthenticationService",
    function($scope, $rootScope, $location, AuthenticationService) {
        AuthenticationService.ClearCredentials();

        $scope.login = function() {

            var foo = "bar"; //Breakpoint hits here twice when loading login.html
        };
    }
    ]);

index.html:

<!DOCTYPE html>
<html ng-app="PVM">
<head>
<title>My Ang</title>
<link href="Content/bootstrap.min.css" rel="stylesheet" />
<link href="Content/bootstrap-theme.min.css" rel="stylesheet" />

</body>
</html>

Login.html:

<div class="container centeredDiv" ng-controller="LoginController">
    <p>Login page</p>
</div>

Answer 1

因为你的控制器在 2 个地方执行。

来自 login.html - ng-controller

<div class="container centeredDiv" ng-controller="LoginController">
    <p>Login page</p>
</div>

来自与路由关联的控制器 - /Login

.when('/Login', {
   controller: 'LoginController',
   templateUrl: 'Login.html'
})

如何解决？您应该从 login.html

中删除 ng-controller 属性

Answer 2

您的模板中不需要 ng-controller login.html，因为它在您的路由中。只需将其删除即可。
