创建登录页面的任何更好方法

Question

我是Angular JS的新手。这是我的第一个基本步骤。我创建了简单的登录页面以访问。我面临的问题是，当我单击login()按钮时， form（）没有提交，并且显示出无效的用户名和密码。我刚刚在其他一些博客中搜索。但是我不正确地理解。

下面有我的代码：

html：

<div class="package" ng-controller="credientials">
    <form ng-submit="loginform()"  class="ng-scope ng-pristine ng-valid">
      <label form="emailinput">Email</label>
      <input type="text" class="form-control ng-pristine ng-valid" ng-model="username">
      <label form="pwdinput">Password</label>
      <input type="password" class="form-control ng-pristine ng-valid" ng-model="password">
    <div>
      <button type="cancel" class="btn" ng-click="toggle_cancel()">Cancel</button>
      <button class="btn btn-primary" ng-click="">Login</button>
    </div><br/>
      <span class="text-danger">{{ error }}</span>
    </form>

角JS：

var app = angular.module('logapp',['ngRoute']);
app.config(function($routeProvider){
            $routeProvider
                .when('/login',{
                    templateUrl : "login.html",
                    controller : "loginctrl"
                })
                .when('/home',{
                    templateUrl : "home.html",
                    controller : "homectrl"
                });
            $routeProvider.otherwise({ redirectTo: '/login'});
        });
 app.controller('credientials',['$scope','$route','$http','$window',function($scope,$route,$http,$window){
   $scope.templates =
                [
                    { url: 'login.html' },
                    { url: 'practice.html'}
                ];
                    $scope.template = $scope.templates[0];
                    $scope.loginform = function (username, password) {
                if ( username === 'admin' && password === '1234') {
                    authentication.isAuthenticated = true;
                    $scope.template = $scope.templates[1];
                    $scope.user = username;
                } else {
                    $scope.error = "Invalid username and password";
                };
              };
      app.factory('authentication', function() {
                return {
                isAuthenticated: false,
                user: null
              }
        });
    }]);

Answer 1

您忘了将工厂的"身份验证"注入控制器。

app.controller('credientials',['$scope','$route','$http','$window',function($scope,$route,$http,$window,authentication){

您必须使用$范围作为用户名和密码

 $scope.username === 'admin' && $scope.password === '1234'

，然后您会看到工厂中的变量iSauthenticated将为true

我在这里更改了您的代码

Answer 2

您需要将用户名和密码放在范围上。也许这会更好：

$scope.username = "";
$scope.password = "";
$scope.loginform = function () {
if ( $scope.username === 'admin' && $scope.password === '1234') {
