Django 模板标签

模板标签

在 Django 模板中，您可以执行编程逻辑，例如执行if声明和for循环。

这些关键字，if和for，在 Django 中称为"template tags"。

为了执行模板标签，我们将它们包围在{% %}括号。

templates/template.html:

{% if greeting == 1 %}
  <h1>Hello</h1>
{% else %}
  <h1>Bye</h1>
{% endif %}

模板标签是告诉 Django 这里有一些不同于纯 HTML 的东西的一种方式。

模板标签允许我们在将 HTML 发送到客户端之前在服务器上进行一些编程。

templates/template.html:

<ul>
  {% for x in mymembers %}
    <li>{{ x.firstname }}</li>
  {% endfor %}
</ul>

在接下来的章节中，您将了解最常见的模板标签。
