cycle 模板标签


示例

在 for 循环的每次迭代中添加一种新颜色

<ul>
{% for x in fruits %}
  <li style='color:{% cycle 'red' 'green' 'blue' 'pink' %}'>
    {{ x }}
  </li>
{% endfor %}
</ul>
运行示例 »

定义和用法

cycle 标签在循环的不同迭代中返回不同的值。

第一次迭代获取第一个值,第二次迭代获取第二个值,依此类推。

您可以拥有任意数量的值。

如果迭代次数多于值的数量,循环将重置并从值 1 开始

示例

循环到达末尾时会重新开始,并继续直到没有更多迭代

<ul>
{% for x in fruits %}
  <li style='color:{% cycle 'red' 'blue' %}'>
    {{ x }}
  </li>
{% endfor %}
</ul>
运行示例 »
