EmberJS 模板局部助手

2018-01-04 13:20 更新

描述

{{partial}}助手將模板作為參數(shù)，并將模板放置在其中。 {{partial}}助手不會更改上下文或范圍。它只是使用模板代替當前范圍。

語句

{{partial "template"}}

例子

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Partial Helper</title>
      <!-- CDN's -->
      <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/3.0.1/handlebars.min.js"></script>

   <body>
      <script type="text/x-handlebars">
         {{outlet}}
      </script>

      <!-- renders the partial helper as an argument and places the outlet in it -->
      <script type="text/x-handlebars" data-template-name="outlet">
         {{partial "partial"}}
      </script>

      <script type="text/x-handlebars" data-template-name="_partial">
         <b>*This is the partial helper*</b><br/>
         Rendering the Controller: {{controller}}
      </script>

      <script type="text/javascript">
         App = Ember.Application.create();
         //route mapping to template outlet
         App.Router.map(function() {
            this.route('outlet');
         });

         App.IndexRoute = Ember.Route.extend({
            redirect: function() {
              //Returns a Promise representing the state of the transition.
              this.transitionTo('outlet');
            }
         });

         //Extending an EmberJs Controller
         App.OutletController = Ember.Controller.extend();
     </script>
   </body>
</html>
