如何从一个页面导航到另一个页面.假设我有一个登录页面,在输入用户名和密码文件后,点击提交按钮需要验证,如果用户名和密码都正确,则需要进入主页.主页内容需要显示.我在这里发布代码.在浏览器中,网址正在发生变化,但内容不会发生变化
的index.html
<html ng-app='myApp'>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"/>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
<script
src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular-route.js"></script>
</head>
<body >
<div id='content' ng-controller='LoginController'>
<div class="container">
<form class="form-signin" role="form" ng-submit="login()">
<h3 class="form-signin-heading">Login Form</h3>
<span><b>Username :</b> <input type="username"
class="form-control" ng-model="user.name" required> </span> </br>
</br> <span><b>Password :</b> <input type="password"
class="form-control" ng-model="user.password" required> </span>
<br><br>
<button class="btn btn-lg btn-primary btn-block" type="submit">
<b>Sign in</b>
</button>
</form>
</div>
<!-- /container -->
</div>
<script src='test.js' type="text/javascript"></script>
</body>
</html>
home.html的
Hello I am from Home page
test.js
var applog = angular.module('myApp',['ngRoute']);
applog.config([ '$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl : 'home.html',
controller : 'HomeController'
}).otherwise({
redirectTo : 'index.html'
});
//$locationProvider.html5Mode(true); //Remove the '#' from URL.
}
]);
applog.controller("LoginController", function($scope, $location) {
$scope.login = function() {
var username = $scope.user.name;
var password = $scope.user.password;
if (username == "admin" && password == "admin") {
$location.path("/home" );
} else {
alert('invalid username and password');
}
};
});
applog.controller("HomeController", function($scope, $location) {
});

的login.html
<div id='content' ng-controller='LoginController'>
<div class="container">
<form class="form-signin" role="form" ng-submit="login()">
<h3 class="form-signin-heading">Login Form</h3>
<span><b>Username :</b> <input type="username"
class="form-control" ng-model="user.name" required> </span> </br>
</br> <span><b>Password :</b> <input type="password"
class="form-control" ng-model="user.password" required> </span>

</div>
<!-- /container -->
</div>
正如@dfsq所说,你需要一个ng-view来放置你的新视图.当然,如果您在索引中添加ng-view,您将看到索引和home的内容.这里的解决方案是创建两个部分视图,一个用于登录身份验证,另一个用于主页.索引文件应仅包含ng-view以及要在整个应用程序中保持不变的元素(菜单,页脚...)
这是我所说的代码:index.html
<html ng-app='myApp'>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"/>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
<script
src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular-route.js"></script>
<script src='test.js' type="text/javascript"></script>
</head>
<body >
<div ng-view></div>
<script src='test.js' type="text/javascript"></script>
</body>
</html>
您的新路线配置
applog.config([ '$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl : 'home.html',
controller : 'HomeController'
})
$routeProvider.when('/', {
templateUrl : 'auth.html',
controller : 'LoginController'
}).otherwise({
redirectTo : 'index.html'
});
//$locationProvider.html5Mode(true); //Remove the '#' from URL.
}
]);
并将您的登录代码放在auth.html文件中
<div id='content' ng-controller='LoginController'>
<div class="container">
<form class="form-signin" role="form" ng-submit="login()">
<h3 class="form-signin-heading">Login Form</h3>
<span><b>Username :</b> <input type="username"
class="form-control" ng-model="user.name" required> </span> </br>
</br> <span><b>Password :</b> <input type="password"
class="form-control" ng-model="user.password" required> </span>
<br><br>
<button class="btn btn-lg btn-primary btn-block" type="submit">
<b>Sign in</b>
</button>
</form>
</div>
<!-- /container -->
</div>
请记住,如果将test.js脚本放在索引中,它将在整个应用程序中.
希望能帮助到你
