Django学习手册 - 自定义分页工具

Posted 2021-01-20 anec

前端代码:

   <div class="xianshi">
        {% for i in info %}
            <ul>
                <li>{{ i }}</li>
            </ul>
        {% endfor %}
        </div>

        <div class="yema">
            {% for x in yemalist%}
                <span>{{ x | safe}}</span>
            {% endfor%}
        </div>

分页函数代码:

def text(yema, count, data):
    start = count * (int(yema) - 1)
    end = count * int(yema)
    info = data[start:end]

    if divmod(len(data), count)[1] != 0:
        s = divmod(len(data), count)[0] + 2
    else:
        s = divmod(len(data), count)[0] + 1

    yema_list = []
    for i in range(1, s):
        i2 = "<a href=‘/display-%s‘>%s</a>" % (i, i)
        yema_list.append(i2)

    if int(yema)==1:
        xy = "<a href=‘/display-%s‘>下一页</a>" % (int(yema) + 1)
        yema_list.append(xy)
    elif 2<=int(yema)<=(s-2):
        sy = "<a href=‘/display-%s‘>上一页</a>"% (int(yema)-1)
        xy = "<a href=‘/display-%s‘>下一页</a>" % (int(yema) + 1)
        yema_list.insert(0,sy)
        yema_list.append(xy)
    elif int(yema)==(s-1):
        sy = "<a href=‘/display-%s‘>上一页</a>" % 1
        # xy = "<a href=‘/display-%s‘>下一页</a>" %(s-1)
        yema_list.insert(0, sy)
        # yema_list.append(xy)

    return {‘info‘: info, "yemalist": yema_list}

 

后台代码:引入函数,赋值,返回参数即可
