我有一个简单的控制器(logincontroller),在加载login.html时会启动两次,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的：

<!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" />
<link href="Content/MyCss.css" rel="stylesheet" />
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1">

</head>
<body>
<div>
<div ng-view></div>
</div>


<script src="//code.jquery.com/jquery-2.0.3.min.js"></script>
<script src="Scripts/bootstrap.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0-beta.2/angular.min.js"></script>

<script src="Scripts/Services/ModalService.js"></script>
<script src="Scripts/Services/AuthenticationService.js"></script>
<script src="Scripts/Controller/LoginController.js"></script>
<script src="Scripts/Controller/ModalController.js"></script>
<script src="Scripts/MyApp.js"></script>


</body>
</html>

的login.html：

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

解决方法

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>

>从与路线相关的控制器 – /登录

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

怎么修？您应该从login.html中删除ng-controller属性
