angularJs--Ui-Router

为什么使用Ui-Router

1、使用Ajax不会留下历史记录

2、用户无法通过URL进入到指定页面

3、Ajax对SEC是个灾难

ngRoute示例代码

app.config(function($routeProvider) {
    $routeProvider.when('/hello', {
        templateUrl: 'tpls/hello.html',
        controller: 'HelloCtrl'
    }).when('/list',{
        templateUrl:'tpls/bookList.html',
        controller:'BookListCtrl'
    }).otherwise({
        redirectTo: '/hello'
    })
});

前端路由的基本原理

HTML5 中新的 history API
路由的核心是给应用定义 "状态"
使用路由机制会影响到应用的整体编码方式(需预先定义好状态)
考虑兼容性问题与 "优雅降级"

(1) Get UI-Router in one of the following ways:

clone & build this repository
download the release (or minified)
link to cdn
via jspm: by running $ jspm install angular-ui-router from your console
or via npm: by running $ npm install angular-ui-router from your console
or via Bower: by running $ bower install angular-ui-router from your console
or via Component: by running $ component install angular-ui/ui-router from your console

(2) Include angular-ui-router.js (or angular-ui-router.min.js) in your index.html, after including Angular itself (For Component users: ignore this step)

(3) Add 'ui.router' to your main module's list of dependencies (For Component users: replace 'ui.router' withrequire('angular-ui-router'))

When you're done, your setup should look similar to the following:

<!doctype html>
<html ng-app="myApp">
<head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
    <script src="js/angular-ui-router.min.js"></script>
    <script>
        var myApp = angular.module('myApp', ['ui.router']);
        // For Component users, it should look like this:
        // var myApp = angular.module('myApp', [require('angular-ui-router')]);
    </script>
    ...
</head>
<body>
    ...
</body>
</html>

Nested States & Views

The majority of UI-Router's power is in its ability to nest states & views.

(1) First, follow the setup instructions detailed above.

(2) Then, add a ui-view directive to the <body /> of your app.

<!-- index.html -->
<body>
    <div ui-view></div>
    <!-- We'll also add some navigation: -->
    <a ui-sref="state1">State 1</a>
    <a ui-sref="state2">State 2</a>
</body>

(3) You'll notice we also added some links with ui-sref directives. In addition to managing state transitions, this directive auto-generates the href attribute of the <a /> element it's attached to, if the corresponding state has a URL. Next we'll add some templates. These will plug into the ui-view within index.html. Notice that they have their own ui-view as well! That is the key to nesting states and views.

<!-- partials/state1.html -->
<h1>State 1</h1>
<hr/>
<a ui-sref="state1.list">Show List</a>
<div ui-view></div>

<!-- partials/state2.html -->
<h1>State 2</h1>
<hr/>
<a ui-sref="state2.list">Show List</a>
<div ui-view></div>

(4) Next, we'll add some child templates. These will get plugged into the ui-view of their parent state templates.

<!-- partials/state1.list.html -->
<h3>List of State 1 Items</h3>
<ul>
  <li ng-repeat="item in items">{{ item }}</li>
</ul>

<!-- partials/state2.list.html -->
<h3>List of State 2 Things</h3>
<ul>
  <li ng-repeat="thing in things">{{ thing }}</li>
</ul>

(5) Finally, we'll wire it all up with $stateProvider. Set up your states in the module config, as in the following:

myApp.config(function($stateProvider, $urlRouterProvider) {
  //
  // For any unmatched url, redirect to /state1
  $urlRouterProvider.otherwise("/state1");
  //
  // Now set up the states
  $stateProvider
    .state('state1', {
      url: "/state1",
      templateUrl: "partials/state1.html"
    })
    .state('state1.list', {
      url: "/list",
      templateUrl: "partials/state1.list.html",
      controller: function($scope) {
        $scope.items = ["A", "List", "Of", "Items"];
      }
    })
    .state('state2', {
      url: "/state2",
      templateUrl: "partials/state2.html"
    })
    .state('state2.list', {
      url: "/list",
      templateUrl: "partials/state2.list.html",
      controller: function($scope) {
        $scope.things = ["A", "Set", "Of", "Things"];
      }
    });
});
