如何向我的 td 添加增量 ID？

Question

我的html文件生成表格：

{% for resp in results %}
    <tr style="counter-increment: count">
         <td>{{ resp }}</td>
         <td>{{ resp.Question_id.Statement }}</td>
    </tr>
{% endfor %}

如何在每次生成新行时为第一个 td 分配一个 id？

Answer 1

使用forloop.countertemplate var:

{% for resp in results %}
    <tr style="counter-increment: {{ forloop.counter }}">
         <td>{{ resp }}</td>
         <td>{{ resp.Question_id.Statement }}</td>
    </tr>
{% endfor %}

Answer 2

用途：

forloop.counter The current iteration of the loop (1-indexed)

{% for item in item_list %}
    {{ forloop.counter }} {# starting index 1 #}
    {{ forloop.counter0 }} {# starting index 0 #}

    {# do your stuff #}
{% endfor %}
