前面的话：
1. 网页引用的bootstrap 中的表格，所以需要引入样式类
2. 第一次写文章，不喜勿喷。有不足的地方，可留言我改正，在此先谢过。
HTML代码：
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>分页</title> <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css"></head><body>
<div class="container"><table class="table table-bordered"> <thead> <tr> <th>序号</th> <th>编号</th> <th>名字</th> </tr> </thead> {% for user in user_list %} <tr> <td>{{ forloop.counter }}</td> <td>{{ user.id }}</td> <td>{{ user.name }}</td> </tr> {% endfor %}</table><nav aria-label="Page navigation"> <ul class="pagination">
{{ page_html|safe }} <!--传值--!>
</ul></nav></div>
</body></html>
views代码：
from django.shortcuts import render, redirect, HttpResponsefrom app01 import models# Create your views here.
def page(request): # 从url取参数 page_num = request.GET.get("p") # 求总页数,每页显示10条数据 total_data = models.Books.objects.all().count() total_page, i = divmod(total_data, 10) # divmod运算可取到整数和余数分别保存在total_page，i 中 try: page_num = int(page_num) if page_num > total_page: page_num = total_page except Exception as e: page_num = 1 # 定义两个变量保存起始数据 print(page_num) data_start = (page_num-1)*10 + 1 data_end = page_num*10
if i: total_page = total_page + 1 # 判断如有余数，加1页
# 页面上总共展示多少页面 max_page = 7 if total_page <= max_page: max_page = total_page half_max_page = max_page // 2 # 页面上展示的页码从哪儿开始 page_start = page_num - half_max_page
# 页面上展示的页码到哪儿结束 page_end = page_num + half_max_page # 前部分 if page_start <= 1: page_start = 1 page_end = max_page # 后部分 if page_end > total_page: page_end = total_page page_start = total_page - max_page + 1 # 自己拼接分页的HTTML代码 html_str_list = [] # 加上首页 html_str_list.append(‘<li><a href="/page/?p=1">首页</a></li>‘) # 加上上一页 if page_num <= 1: html_str_list.append( ‘<li class="disabled"><a href="#" aria-label="Previous"><span aria-hidden="true">«</span></a></li>‘) else: html_str_list.append( ‘<li><a href="/page/?p={0}" aria-label="Previous"><span aria-hidden="true">«</span></a></li>‘.format( page_num - 1))

# all_user = models.UserInfo.objects.all()[10: 20] all_user = models.Books.objects.filter(id__gte=data_start, id__lte=data_end) print(all_user) return render(request, "page.html", {"user_list": all_user, "page_html": page_html})
