用Jinja遍历项目，每第5个项目后添加div [英] Looping over items with Jinja, adding in div after every 5th item

问题描述

我有100个高尔夫球场的清单，我想插入一个div，其中包含每五个高尔夫球场后的广告图片.我将如何去做?

I have a list of 100 golf courses and I'm looking to insert a div, containing an image for an ad after every fifth course. How would I go about doing this?

• 由于leovp的问题，我已经更新了原始代码段 建议在下面进行编辑.我在仅显示{% if content.featured == "Test" %}时遇到了麻烦，并且想知道如何关闭if-else语句.

• I've updated my original code snippet because off of leovp's suggested edited below. I'm having trouble showing only {% if content.featured == "Test" %} and wondering how I should closing my if-else statement.

    {% for content in COPY.courses %}
            <div class="course course--featured">
                <a href=""><img src="" class="course__image image--region"></a>

                <div class="course__inner">
                    <div class="course__wrapper">
                        {% if content.state == "MO" %}
                            <p class="course__state">Missouri</p>
                        {% elif content.state == "IL" %}
                            <p class="course__state">Missouri</p>
                        {% endif %}
                    </div>

                    <div class="course__wrapper">
                        <a href=""><p class="course__name name--region">{{ content.name }}</p></a>
                    </div>
                    <p class="course__desc">{{ content.description }}</p>
                </div>
            </div>

    {% if loop.index % 5 == 0 %}
    <div class="advertising advertising--inline">
        <div class="ad ad--rect">

            <div class="text-center hidden-xs">
                <div id="fixed-leaderboard-region-top"
                    class="dfp-ad"
                    data-dfp-custom-pos="fixed-leaderboard-top, htf"
                    data-dfp-size="[728,90]">
                </div>
            </div>

            <div class="text-center hidden-sm hidden-md hidden-lg">
                <div id="fixed-leaderboard-region-top-mobile"
                    class="dfp-ad"
                    data-dfp-custom-pos="fixed-leaderboard-top, htf"
                    data-dfp-size="[320,50]">
                </div>
            </div>
        </div>
    </div>
    {% endif %}
    {% endfor %}
</div>

• 我已经研究过使用 batch 从此堆栈溢出 question 看起来很相似，但是我不确定这是否可以解决我的问题?

• I've looked into using batch from this Stack Overflow question that seemed similar, but I'm unsure if this solves my problem?

{COPY.courses中内容的%%} {％如果content.featured ==测试"％}

{% for content in COPY.courses %} {% if content.featured == "Test" %}

<div class="course__inner">
    <div class="course__wrapper">
        {% if content.state == "MO"%}
        <p class="course__state">Missouri</p>
        {% elif content.state == "IL" %}
        <p class="course__state">Illinois</p>
        {% endif %}
    </div>

    <div class="course__wrapper">
        <a href=""><p class="course__name name--home">{{ content.name }}</p></a>
    </div>
    <p class="course__desc">{{ content.description }}</p>
</div>

{％endif％} {％endfor％}

{% endif %} {% endfor %}

推荐答案

在迭代时，您可以获取当前索引并检查它是否可以被5整除:

While iterating, you can get the current index and check if it's divisible by 5:

{% set count = 0 %}
{% for content in COPY.courses %}
{% if content.featured == "Test" %}
<div class="course course--featured">
    <a href=""><img src="" class="course__image image--home"></a>
    [...]
    </div>
</div>

{% set count = count + 1 %}
{% if count % 5 == 0 %}
    <!-- additional content once every 5 courses -->
{% endif %}
{% endif %}
{% endfor %}

注意:此方法在2.10版本之后不再有效.

NOTE: This approach no longer works after version 2.10.
