javascript - Angular Controller 不工作

Question

我是 Angular 的新手 我的 Angular Controller 是:

var chatApp = angular.module('chatApp.controllers', []);

chatApp.controller('loginController', ['$scope', function($scope) {
$scope.user_name="name";
$scope.user_password="name";
}]);

app.js 是:

'use strict';
angular.module('chatApp', [
'ui.router',
'chatApp.filters',
'chatApp.services',
'chatApp.directives',
'chatApp.controllers'
]).config(function($stateProvider, $urlRouterProvider) {
$stateProvider
    .state('login', {
        url: "/login",
        templateUrl: "partials/login.html",
        controller : "loginController"
    })
});

login.html 是:

<div>
<div id="wrapper">
    <form name="login-form" class="login-form" action="" method="post">
        <div class="header">
            <h1>Login Form</h1>
        </div>
        <div class="content">
            <input name="username" type="text" class="input username" placeholder="{{user_name}}" />
            <div class="user-icon"></div>
            <input name="password" type="password" class="input password" placeholder="{{user_password}}" />
            <div class="pass-icon"></div>
        </div>
    </form>
</div>

我使用 stateprovider 进行路由。 但是，它没有在占位符中显示任何内容。这是什么原因？

使用 ng-model 代替 {{}} 解决了问题。

<div class="content">
            <input name="username" type="text" class="input username" placeholder="username" ng-model="user_name" />
            <div class="user-icon"></div>
            <input name="password" type="password" class="input password" placeholder="password" ng-model="user_password"/>
            <div class="pass-icon"></div>
        </div>
