EmberJS 路由器基于其他应用程序状态

2018-01-03 18:27 更新

描述

如果beforeModel钩子没有中止，剩下的钩子（model，afterModel，setupController，renderTemplate）将被正常执行，这将导航到前一个URL。

语句

Ember.Route.extend({
   activate: function() {
      var controller = this.controllerFor('application');
      controller.set('lastFilter', this.templateName);
   }
});

例子

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Based on other Application State</title>
      <!-- CDN's -->
      <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/3.0.1/handlebars.min.js"></script>
      <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/ember.js/1.10.0/ember.min.js"></script>
      <script src="https://builds.emberjs.com/tags/v1.10.0-beta.3/ember-template-compiler.js"></script>
      <script src="https://builds.emberjs.com/release/ember.debug.js"></script>
      <script src="https://builds.emberjs.com/beta/ember-data.js"></script>
   </head>
   <body>
      <script type="text/x-handlebars" data-template-name="index">
         <h3>{{#link-to "section1"}}Click for to get section1{{/link-to}}</h3>
      </script>

      <script type="text/x-handlebars" data-template-name="section1">
         <h2>section 1</h2>
      </script>

      <script type="text/x-handlebars" data-template-name="section2">
         <!-- section2 contents -->
         <h2>This is section 2</h2>
         <p>You can conditionally transition based on some other application state.</p>
      </script>

      <script type="text/javascript">
         App = Ember.Application.create();

         App.Router.map(function() {
            this.route('section1');
            this.route('section2');
         });

         App.Section1Route = Ember.Route.extend({
            //redirecting to the section2 route via section1 route
            redirect: function() { this.transitionTo('section2'); }
         });
      </script>
   </body>
</html>
