JavaEE AngularJS Bootstrap: routes, templates, redirection and params

A simple example about navigation inside a web application, using native AngularJS components.

Why ?

Using Templates provides a more reusable View and less duplicate code.

Using Route provide a better decoupling between View and Controller.

Using Redirection inside Controller allows View to not contains compelx logic, but only datas and states.

Using Animation to Enhance User Experience with more transitions.

How to ?

By using AngularJs’ rout, location and animation components.

Template

The template contains ng-view. index.jsp

<html ng-app="myApp">
<head>
<!-- LIBS CSS -->
<link rel="stylesheet" href="webjars/bootstrap/${bootstrap.version}/css/bootstrap.css">
<link rel="stylesheet" href="styles/main.css">
<!-- LIBS JS -->
<script src="webjars/angularjs/${angularjs.version}/angular.js"></script>
<script src="webjars/angularjs/${angularjs.version}/angular-route.js"></script>
<script src="webjars/angularjs/${angularjs.version}/angular-animate.js"></script>
<!-- YOUR JS -->
<script src="js/app.js"></script>
<script src="js/controllers/homeCtrl.js"></script>
<script src="js/controllers/testRouteCtrl.js"></script>
<script src="js/controllers/testParamsCtrl.js"></script>
</head>
<body>
<div class="container">
  <!-- MAIN CONTENT AND INJECTED VIEWS -->
  <div id="main">
    <!-- angular templating -->
    <!-- this is where content will be injected -->
    <div ng-view class="view-animate"></div>
  </div>
</div>
</body>
</html>

home.html

<h1>Home</h1>
<div>
  <button class="btn btn-default" ng-click="goToTestRoute()">
    Test Route <span class="glyphicon glyphicon-chevron-right"></span>
  </button>
</div>
<div class="btn-group-vertical" role="group">
  <button class="btn btn-default" ng-click="goToTestParams(1)">
    Test Params 1 <span class="glyphicon glyphicon-chevron-right"></span>
  </button>
  <button class="btn btn-default" ng-click="goToTestParams(2)">
    Test Params 2 <span class="glyphicon glyphicon-chevron-right"></span>
  </button>
  <button class="btn btn-default" ng-click="goToTestParams(3)">
    Test Params 3 <span class="glyphicon glyphicon-chevron-right"></span>
  </button>
</div>

Router

App file contains the main router for app’s paths, providding a View/Controller assocation for each route. app.js

var myApp = angular.module(
  'myApp',
  [ 'ngAnimate', 'ngRoute']);
 
myApp.config(function($routeProvider) {
  $routeProvider
  // route for the home page
  .when('/', {
    templateUrl : 'views/home.html',
    controller  : 'homeCtrl'
  })
  // route for the testRoute page
  .when('/testroute', {
    templateUrl : 'views/testRoute.html',
    controller  : 'testRouteCtrl'
  })
  // route for the testParams page 
  .when('/testparams/:id', {
    templateUrl : 'views/testParams.html',
    controller  : 'testParamsCtrl'
  })
  // default redirection
  .otherwise({
    redirectTo: '/'
  });
});

Test Route

Controller contains redirection, triggered by a View click event.

homeCtrl.js

myApp.controller('homeCtrl', function($scope, $location) {
     
  $scope.goToTestRoute = function() {
    $location.path( "/testroute" );   
  }
   
  $scope.goToPageB = function() {
    $location.path( "/pageb" );   
  }
   
  $scope.goToTestParams= function(id) {
    $location.path( "/testparams/"+id );   
  }
});

testRouteCtrl.js

myApp.controller('testRouteCtrl', function($scope, $location) {
     
  $scope.goBack = function() {
    $location.path( "/" );   
  }
});

testRoute.html

<h1>Test Route</h1>
<button class="btn btn-default" ng-click="goBack()">
  <span class="glyphicon glyphicon-chevron-left"></span> Home
</button>

Test params

A route can be parameterized, like in API’s path.

testParamsCtrl.js

myApp.controller('testParamsCtrl', function($scope, $route, $routeParams, $location) {
     
  $scope.goBack = function() {
    $location.path( "/" );   
  }
   
  $scope.$route = $route;
  $scope.$location = $location;
  $scope.$routeParams = $routeParams;
});

testParams.html

<h1>Test Params</h1>
<p>This is page {{$routeParams.id}} !</p>
<pre>
  $location.path() = {{$location.path()}}
  $route.current.templateUrl = {{$route.current.templateUrl}}
  $route.current.params = {{$route.current.params}}
  $route.current.scope.name = {{$route.current.scope.name}}
  $routeParams = {{$routeParams}}
</pre>
<button class="btn btn-default" ng-click="goBack()">
  <span class="glyphicon glyphicon-chevron-left"></span> Home
</button>

Animation

CSS is linked to view-animate AngularJs’ class.

main.css

.view-animate-container {
  position:relative;
  height:100px!important;
  background:white;
  border:1px solid black;
  height:40px;
  overflow:hidden;
}
 
.view-animate {
  padding:10px;
}
 
.view-animate.ng-enter, .view-animate.ng-leave {
  transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
 
  display:block;
  width:100%;
  border-left:1px solid black;
 
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:0;
  padding:10px;
}
 
.view-animate.ng-enter {
  left:100%;
}
.view-animate.ng-enter.ng-enter-active {
  left:0;
}
.view-animate.ng-leave.ng-leave-active {
  left:-100%;
}
