将分页代码放在include，这样分页功能就可以重用了
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> {% if posts.has_previous %} <a href="/index1.html?p={{ posts.previous_page_number }}">上一页</a> {% endif %} {% for i in posts.paginator.per_num_range %} {% if i == posts.number %} <a style="font-size: 30px;" href="/index1.html?p={{ i }}">{{ i }}</a> {% else %} <a href="/index1.html?p={{ i }}">{{ i }}</a> {% endif %} {% endfor %} {% if posts.has_next%} <a href="/index1.html?p={{ posts.next_page_number }}">下一页</a> {% endif %} <span>{{ posts.number }}/{{ posts.paginator.num_pages}}</span> </body> </html>
