javascript - 加载模板时调用操作函数(Ember.js)

Question

我的应用程序当前存在问题，我想在渲染页面时加载大量数据

与 stackoverflow.com 一样，当客户端单击导航栏上的个人资料链接时，会呈现一个新页面，其中包含从 API 获取的大量数据。

在 ember 中，这将如何完成？我正在向我实现的 API 发出 GET 请求，并且我想显示响应中的所有数据。但是在我所处的情况下我将如何调用这样的函数。代码如下:

index.html:

<script type="text/x-handlebars">
<div id="header">
  <div id="wrapper">
    <a id="logo" href="/socialWOD">&nbsp</a>
    <ul id="nav">
      <li>{{#link-to "about" activeClass="selected"}}About{{/link-to}}</li>
      <li>{{#link-to "wods" activeClass="selected"}}WODs{{/link-to}}</li>
      <li>{{#link-to "login" activeClass="selected"}}Login{{/link-to}}</li>
      <li id="search">
        <form>
          <input type="text" id="st-search-input" class="st-search-input" autocomplete="off"
                  autocorrect="off" autocapitalize="off" style="outline: none;" placeholder="Search"/>
        </form>
      </li>
    </ul>
  </div>
</div>
{{outlet}}
</script>


<!-- WODs List Template (Start)-->
<script type="text/x-handlebars" data-template-name="wods">
<div id="socialWODapp">
  <div id="newentry">
    <h1>socialWOD</h1>
    {{input type="text" id="new-WOD-wod-category" placeholder="Enter new WOD category name" value=category action="create"}}
    {{input type="text" id="new-WOD-name" placeholder="Enter WOD name" value=name action="create"}}
    {{input type="text" id="new-WOD-description" placeholder="Enter WOD description" value=description action="create"}}
    {{input type="text" id="new-WOD-workout" placeholder="Enter WOD workout" value=workout action="create"}}
  </div>

  <div id="main">
    <ul id="wodlist">
      {{#each}}
      <h1>{{wod_category}}</h1>
      <li>
        <input type="checkbox" class="toggle">
        <label>{{name}}</label><button class="destroy"></button>
      </li>
      <li>{{description}}</li>
      <li>{{workouts}}</li>
      {{/each}}
    </ul>
    <input type="checkbox" id="toggle-all">
  </div>
</div>
</script>
<!-- WODs List Template (End)-->

wod_controller.js:

SocialWOD.WodsController = Ember.ArrayController.extend({
        actions: {
            getWODs: function() {
                Ember.$.post('/socialWOD_API/?wods', data).then(function(response) {
                        console.log(response.message);
                    });
            }
        }
}

注意:WOD 代表每日锻炼

当呈现 WODs 页面时，如何调用 getWODs()？我可以使用静态 WOD FIXTURES，但是当我实现 GET 请求时，当然不会调用或获取任何内容。大家有什么想法吗？

编辑:甜蜜...我应该知道...如此简单...这就是我所做的:

SocialWOD.WodsRoute = Ember.Route.extend({
        model: function() {
            Ember.$.get('/socialWOD_API/?wods').then(function(response) {
                    return response;
                });
        }
    });

现在我遇到了有关呈现信息的问题...在控制台中，我得到以下信息:

[{"objectId":"086f8db206","wod_category":"The New Girls","name":"Annie","description":"50-40-30-20-10 rep rounds, for time","workouts":"[\"Double-unders\",\"Sit-ups\"]","createdAt":"2014-07-31 13:24:33","modifiedAt":"2014-07-31 13:24:33"},{"objectId":"389b7518f4","wod_category":"The New Girls","name":"Eva","description":"5 rounds for time","workouts":"[\"Run 800 meters\",\"30 x 2-pood KB swings\",\"30 x Pull-ups\"]","createdAt":"2014-07-31 13:24:33","modifiedAt":"2014-07-31 13:24:33"},{"objectId":"7d91a57aea","wod_category":"The New Girls","name":"Kelly","description":"5 rounds for time","workouts":"[\"Run 400 meters\",\"30 x Box jump 24\"\",\"30 x Wall-ball\"]","createdAt":"2014-07-31 13:24:33","modifiedAt":"2014-07-31 13:24:33"},{"objectId":"07b6fa146c","wod_category":"The New Girls","name":"Lynne","description":"5 rounds for time","workouts":"[\"Max rep BW Bench\",\"Max rep BW Pull-ups\"]","createdAt":"2014-07-31 13:24:33","modifiedAt":"2014-07-31 13:24:33"},{"objectId":"0e834bd262","wod_category":"The New Girls","name":"Nicole","description":"As many rounds as possible in 20 minutes","workouts":"[\"Run 400 meters\",\"Max rep Pull-ups\"]","createdAt":"2014-07-31 13:24:33","modifiedAt":"2014-07-31 13:24:33"}] 

为什么我的模板没有呈现信息？抱歉，我对 Ember 和使用 Web 框架非常陌生...纯 php 看起来简单得多:P

您需要实际返回对路由的 get 调用;)

SocialWOD.WodsRoute = Ember.Route.extend({
        model: function() {
          return Ember.$.get('/socialWOD_API/?wods').then(function(response) {
                    return response;
                });
        }
});
