效果演示：
github地址：https://github.com/mncu/django_projects/tree/master/django_projects/pagination_test
本例中总页数为30页，显示页数为12页，当前页的前排页数为4，后排页数为5
将分页分为三种情况：
1 当前页为第1页到第7页的时候，无省略页，且12个位置的内容是不变
2 当前页为第8页到第25页时，位置1与位置2内容不变，当前页一直处于位置7,
3 当前页为第25页到第30页时，位置1与位置2内容不变，位置8到位置12的内容不变，当前页在位置8到位置12之中变换
自定义标签代码：
from django import template register = template.Library() @register.assignment_tag def pagination(current_page,paginator,num_of_displaypages=10,num_of_backpages=4): # current_page is a django.core.paginator.Page 's instance # paginator is a django.core.paginator.Paginator 's instance # num_of_frontpages = num_of_displaypages - num_of_backpages -3 html='' # 当总页数小于等于 显示页数 时，则将总页数全部显示 if paginator.num_pages <= num_of_displaypages : for i in range(1,paginator.num_pages+1): html+= '<li ><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >%s </a></li>'%(i,i) return html # 第一种情况 elif current_page.number <= num_of_displaypages-num_of_backpages: for i in range(1,num_of_displaypages+1): html+= '<li ><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >%s </a></li>'%(i,i) return html # 第二种情况 elif num_of_displaypages-num_of_frontpages <= current_page.number <= paginator.num_pages-num_of_backpages : html = ''' <li><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >1</a></la> <li class="disabled"><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >...</a></la> ''' for i in range(current_page.number-num_of_frontpages,current_page.number+num_of_backpages+1): html+='<li><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >%s</a></la>'%(i,i) return html # 第三种情况 else: html = ''' <li><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >1</a></la> <li class="disabled"><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >...</a></la> ''' for i in range(paginator.num_pages-num_of_backpages-num_of_frontpages,paginator.num_pages+1): html+='<li><a href="" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >%s</a></la>'%(i,i) return html
来看html代码
{% load mytags %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!-- 新 Bootstrap 核心 CSS 文件 -->
<link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css" rel="external nofollow" >
<!-- 可选的Bootstrap主题文件（一般不用引入） -->
<link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap-theme.min.css" rel="external nofollow" >
<!-- jQuery文件。务必在bootstrap.min.js 之前引入 -->
<script src="/UploadFiles/2021-04-08/jquery.min.js">
看看view函数：
from django.shortcuts import render
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
# Create your views here.
def index(request):
obj_list = ['page01','page02','page03','page04','page05','page06','page07','page08','page09','page10',
'page11','page12','page13','page14','page15','page16','page17','page18','page19','page20',
'page21','page22','page23','page24','page25','page26','page27','page28','page29','page30',]
#create a paginator instance
paginator = Paginator(obj_list,1)
#Get the page_number of current page
current_page_num = request.GET.get('page')
try:
current_page = paginator.page(current_page_num)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
current_page = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
current_page = paginator.page(paginator.num_pages)
return render(request,'index.html',
{'current_page': current_page,
'paginator': paginator
})
