Django 数据自定义分页
XSS：
{{ page_str|safe }}
from django.utils.safestring import mark_safe
mark_safe(page_str)#保证回传数据安全的
前端页面：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .pagination .page_list{ display: inline-block; padding: 5px; background-color: cyan; } .pagination .page_list.active{ background-color: brown; color: white; } </style> </head> <body> <ul> {% for itme in li %} <li>{{ itme }}</li> {% endfor %} </ul> <div> <select id="ps" onchange="changePageSize(this)"> <option value="10">10</option> <option value="30">30</option> <option value="50">50</option> <option value="100">100</option> </select> </div> <div class="pagination"> {{ page_str }} </div> </body> </html>
