如何用 jekyll 和 liquid 打印数组

Question

我有一个 json 文档，其中包含一些数据

{"teams":[{"team":"Team A","evolution":[1,2]},{"team":"Team B","evolution":[3,4]}]}

我尝试用液体将其打印到我的视图

{% for team in teams %}
  <tr>
    <td><a href="#">{{team.team}}</a></td>
    <td>{{team.evolution}}</td>
  </tr>
{% endfor%}

html 结果是

<tr>
    <td><a href="#">Team A</a></td>
    <td>12</td>
</tr>
<tr>
    <td><a href="#">Team B</a></td>
    <td>34</td>
</tr>

但我想打印的是第二个 <td>

的原始数组

<tr>
    <td><a href="#">Team A</a></td>
    <td>[1,2]</td>
</tr>
<tr>
    <td><a href="#">Team B</a></td>
    <td>[3,4]</td>
</tr>

Answer 1

假设您从 _data/teams.json 文件中获取数据，这可行：

{% assign teams = site.data.teams.teams %}
<table>
{% for team in teams %}
  <tr>
    <td><a href="#">{{team.team}}</a></td>
    <td>{{team.evolution | join: "," | prepend: "[" | append: "]"}}</td>
  </tr>
{% endfor%}
</table>
