Ember/ Liquid - 每个语句的多维数组

Question

我在使用 ember #each 语句时遇到了一些困难。我想从下面的 HTML 代码中的多维数组中打印第 [0] 和第 [1] 位置值。即，我想在单独的 HTML 代码块中打印值 Product X、Y、Z 和 GROUP A、B、C。 this.get(0) 不起作用。

var uiTags = [
   ['**Product X**','GROUPA', '350'],
   ['**Product Y**','GROUPB', '150'],
   ['**Product Z**','GROUPC', '575']
];

HTML 代码：

<ul class="list-group list-group-menu">
  {% raw %}{{#each uiTags}}{% endraw %}

   <!-- Print product name start (This block should print the product name) -->
    <li class="list-group-item"><a href="#">          
      <div class="checkbox checkbox-primary">
        <input type="checkbox" checked id="map-filter-{% raw %}{{ @index }}{% endraw %}" value="{% raw %}{{ this }}{% endraw %}"/>
        <label for="map-filter-{% raw %}{{ @index }}{% endraw %}">{% raw %}{{ this }}{% endraw %}</label>
      </div></a>
    </li>
   <!-- Print product name end-->

   <!-- Print group name start (This block should print the group name) -->
    <li class="list-group-item"><a href="#">          
      <div class="checkbox checkbox-primary">
        <input type="checkbox" checked id="map-filter-{% raw %}{{ @index }}{% endraw %}" value="{% raw %}{{ this }}{% endraw %}"/>
        <label for="map-filter-{% raw %}{{ @index }}{% endraw %}">{% raw %}{{ this }}{% endraw %}</label>
      </div></a>
    </li>
   <!-- Print group name end-->


  {% raw %}{{/each}}{% endraw %}
</ul>

Answer 1

You can use the get helper to access a specific index.:

<ul>
  {{#each model as |row|}}
    <li>
      <ul>
        <li>{{get row "0"}}</li>
        <li>{{get row "1"}}</li>
      </ul>
    </li>
  {{/each}}
</ul>

And an ember twiddle with it.
