python - 为什么扩展模板时我的表单不起作用

标签 python flask jinja2

您好，当我使用 jinja2 扩展模板时，我的所有表单都不起作用。如何使表单与模板一起使用？

目标是能够拥有一个父文件，然后我可以将所有子文件添加到该父文件中，而不必每次都添加页眉和页脚。这次我尝试添加表单不会让表单具有交互性。该表单就像一个图像，您无法选择任何内容或与任何内容交互。

我的父文件是:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <link rel="shortcut icon" href="/static/img/favicon.ico" type="image/x-icon">

最佳答案

你的CSS有问题。样式被应用到 Header.html 中定义的元素，导致您的表单隐藏在另一个元素下面。如果您检查页面，您将看到 div.col6 位于 div#content 之上。这是由 layout.css 中的以下两行引起的:

#content{display:block; float:left; width:600px;}

#header, #topbar, #intro, #services, #breadcrumb, #container, #footer, #copyright{display:block; position:relative; width:960px; margin:0 auto;}

第一行中的 float:left; 与第二行中的 position:relative; 相结合导致了这种情况。

在不知道设计的最终目标的情况下，很难说出正确的解决方案是什么，但你有三个选择:

  1. 删除float:left;。
  2. 删除 position:relative;，或者至少重新排列 CSS，使其不会应用于 #footer。
  3. 清除 float 。您可以使用以下方法来做到这一点:
<div class="wrapper col5">
  <div id="container">
    <div id="content">
      {% block content %}{% endblock %}
      <div class="clear"></div>
    </div>
  </div>
</div>
