如何向td添加增量ID？

Question

我的html文件生成一个表：

{% 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将id分配给第一个td？

Answer 1

使用：

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 %}

使用forloop.counter模板var：

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