layui 框架与BootCSS框架相似都属于前端美化框架，区别在于BootCSS更加专业，而LayUI则更多的是面向于后端开发者，所以在组织形式上毅然采用了几年前的以浏览器为宿主的类 AMD 模块管理方式，却又并非受限于 CommonJS 的那些条条框框，它拥有自己的模式，更加轻量和简单。

官方示例1： 简单的页面前端布局。

<link rel="stylesheet" href="https://www.blib.cn/cdn/layui/css/layui.css", media="all">
<script src="https://www.blib.cn/cdn/layui/layui.js"></script>
<table class="layui-hide" id="demo" lay-filter="test"></table>

<script type="text/html" id="barDemo">
  <a class="layui-btn layui-btn-primary layui-btn-xs" lay-event="detail">查看</a>
  <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
  <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
</script>

<script>
layui.use('table', function(){
  var table = layui.table;
  //执行一个 table 实例
  table.render({
    elem: '#demo'
    ,height: 420
    ,url: '/host' //数据接口
    ,title: '用户表'
    ,page: true //开启分页
    ,toolbar: 'default' //开启工具栏，此处显示默认图标，可以自定义模板，详见文档
    ,totalRow: true //开启合计行
    ,cols: [[
      {type: 'checkbox', fixed: 'left'}
      ,{field:'id', title:'ID', width:80,   sort: true}
      ,{field:'hostname', title:'用户名', width:120}
      ,{field:'hostaddr', title:'主机地址',width:120}
      ,{fixed: 'right', title:'操作', toolbar: '#barDemo', width:200}
    ]]
  });
 //监听头工具栏事件
  table.on('toolbar(test)', function(obj){
    var checkStatus = table.checkStatus(obj.config.id)
    ,data = checkStatus.data; //获取选中的数据
    switch(obj.event){
      case 'add':
        layer.msg('添加');
      break;
      case 'update':
        if(data.length === 0){
          layer.msg('请选择一行');
        } else if(data.length > 1){
          layer.msg('只能同时编辑一个');
        } else {
          layer.alert('编辑 [id]：'+ checkStatus.data[0].id);
        }
      break;
      case 'delete':
        if(data.length === 0){
          layer.msg('请选择一行');
        } else {
          layer.msg('删除');
        }
      break;
    };
  });

  //监听行工具事件
  table.on('tool(test)', function(obj){ //注：tool 是工具条事件名，test 是 table 原始容器的属性 lay-filter="对应的值"
    var data = obj.data //获得当前行数据
    ,layEvent = obj.event; //获得 lay-event 对应的值
    if(layEvent === 'detail'){
      layer.msg('查看操作');
    } else if(layEvent === 'del'){
      layer.confirm('真的删除行么', function(index){
        obj.del(); //删除对应行（tr）的DOM结构
        layer.close(index);
        //向服务端发送删除指令
      });
    } else if(layEvent === 'edit'){
      layer.msg('编辑操作');
    }
  });
});

Django 实现表格分页： 接着就是实现分页了，使用layui框架配合Django自带的分页组件，即可完成分页：

代码总结

实现简单表格分页: layui 是一个完整的前端开发框架,利用它可以快速构建分页应用,比BootStrap更加灵活.

首先我们创建一个models.py 规划好我们的表结构,并插入一些测试数据.

# models.py
from django.db import models

class HostDB(models.Model):
    id = models.AutoField(primary_key=True)
    hostname = models.CharField(max_length=64)
    hostaddr = models.CharField(max_length=64)
    hostmode = models.CharField(max_length=64)

插入完成数据后,我们接着创建前端页面并引用LayUi框架.

<!--name: index.html-->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="https://www.layuicdn.com/layui-v2.5.6/css/layui.css">
    <script type="text/javascript" src="https://www.layuicdn.com/layui-v2.5.6/layui.js"></script>
</head>
<body>
<table class="layui-hide" id="demo"></table>
    <script type="text/javascript">
    layui.use('table', function(){
      var table = layui.table;
      table.render({
          elem: '#demo',
          url:'/get_page',
          method:'get',
          toolbar: '#toolbarDemo'         // 显示工具条
          ,request: {
                  pageName: 'pageIndex',  // 页码的参数名称，默认：page
                  limitName: 'pageSize'   // 每页数据量的参数名，默认：limit
          }
          ,response: {
                  statusName: 'code',     // 规定数据状态的字段名称，默认：code
                  statusCode: 0,          // 规定成功的状态码，默认：0
                  msgName: 'msg',         // 规定状态信息的字段名称，默认：msg
                  countName: 'DataCount', // 规定数据总数的字段名称，默认：count
                  dataName: 'data'        // 规定数据列表的字段名称，默认：data
          }
        ,cols: [[
          {type: 'checkbox', fixed: 'left'},
          {field:'id', title:'主机ID', width:100, sort: true},
          {field:'hostname', title:'主机名称', width:120},
          {field:'hostaddr', title:'主机地址', width:120},
          {field:'hostmode', title:'主机组', width:120},
        ]]
        ,page: {
            layout: ['limit', 'count', 'prev', 'page', 'next', 'skip'],     // 自定义分页布局
            curr: 1,      // 设置默认起始页1
            groups: 10,   //只显示10个连续页码,就是说显示10个可见页其他的省略
            first: false, // 不显示首页
            last: false   // 不显示尾页
        },
        limit: 5,
        limits: [5,10,15,20,25]
      });
    });
    </script>
</body>
</html>

接着创建view.py视图文件,并在后台做好分页处理.

# views.py

from django.shortcuts import render,HttpResponse
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
from MyWeb import models
import json

def index(request):
    return render(request,"index.html")

def get_page(request):
    data = models.HostDB.objects.all()
    dataCount = data.count()
    pageIndex = request.GET.get("pageIndex")
    pageSize = request.GET.get("pageSize")
    print("当前索引:{} 当前大小:{}".format(pageIndex,pageSize))
    print("所有记录:{} 数据总条数:{}".format(data,dataCount))

    # 将数据组装成字典后放入data_list列表
    data_list,ref_data = [],[]
    for item in data:
        dict = { 'id':item.id , 'hostname':item.hostname, 'hostaddr':item.hostaddr, 'hostmode':item.hostmode }
        data_list.append(dict)

    # 使用分页器分页
    pageInator = Paginator(data_list,pageSize)
    context = pageInator.page(pageIndex)
    for item in context:
        ref_data.append(item)
    # 返回分页格式
    data = { "code": 0,"msg": "ok","DataCount": dataCount,"data": ref_data }
    return HttpResponse(json.dumps(data))

最后增加路由映射记录,记录值如下所示.

# name: url.py
from django.contrib import admin
from django.urls import path
from MyWeb import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',views.index),
    path('get_page/',views.get_page)
]

给表格添加搜索功能: 接着我们继续给这个页面添加新功能，这次就先加上一个重载搜索功能吧,前端代码只需要稍微修改一下.

<!--name: index.html-->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="https://www.layuicdn.com/layui-v2.5.6/css/layui.css">
    <script type="text/javascript" src="https://www.layuicdn.com/layui-v2.5.6/layui.js"></script>
    <script src="https://code.jquery.com/jquery-3.2.0.min.js"></script>
</head>
<body>

<div class="demoTable">
  搜索名称：
  <div class="layui-inline">
    <input class="layui-input" name="id" id="demoReload" autocomplete="off">
  </div>
  <button class="layui-btn" data-type="reload">搜索</button>
</div>

<table class="layui-hide" id="demo" lay-filter="test"></table>
    <script type="text/javascript">
    layui.use('table', function(){
      var table = layui.table;
      table.render({
          elem: '#demo',
          url:'/get_page',
          method:'get',
          id: 'testReload'
          ,request: {
                  pageName: 'pageIndex',  // 页码的参数名称，默认：page
                  limitName: 'pageSize'   // 每页数据量的参数名，默认：limit
          }
          ,response: {
                  statusName: 'code',     // 规定数据状态的字段名称，默认：code
                  statusCode: 0,          // 规定成功的状态码，默认：0
                  msgName: 'msg',         // 规定状态信息的字段名称，默认：msg
                  countName: 'DataCount', // 规定数据总数的字段名称，默认：count
                  dataName: 'data'        // 规定数据列表的字段名称，默认：data
          }
        ,cols: [[
          {type: 'checkbox', fixed: 'left'},
          {field:'id', title:'主机ID', width:100, sort: true},
          {field:'hostname', title:'主机名称', width:120},
          {field:'hostaddr', title:'主机地址', width:120},
          {field:'hostmode', title:'主机组', width:120},
        ]]
        ,page: {
            layout: ['limit', 'count', 'prev', 'page', 'next', 'skip'],     // 自定义分页布局
            curr: 1,      // 设置默认起始页1
            groups: 10,   //只显示10个连续页码,就是说显示10个可见页其他的省略
            first: false, // 不显示首页
            last: false   // 不显示尾页
        },
        limit: 5,
        limits: [5,10,15,20,25]
      });

    var $ = layui.$, active = {
        reload: function(){
          var demoReload = $('#demoReload');
          console.log(demoReload);
          //执行重载
          table.reload('testReload', {
            url:"/search_page",
            page: {
              curr: 1,
              limits: [1]
            }
            ,where: {
                hostname: demoReload.val()
            }
          }, 'data');
        }
      };
    // 绑定搜索事件
      $('.demoTable .layui-btn').on('click', function(){
            var type = $(this).data('type');
            active[type] ? active[type].call(this) : '';
          });
    });
    </script>
</body>
</html>

然后修改视图层views.py增加搜索方法的实现过程.

from django.shortcuts import render,HttpResponse
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
from MyWeb import models
import json

def index(request):
    return render(request,"index.html")

def get_page(request):
    data = models.HostDB.objects.all()
    dataCount = data.count()
    pageIndex = request.GET.get("pageIndex")
    pageSize = request.GET.get("pageSize")
    print("当前索引:{} 当前大小:{}".format(pageIndex,pageSize))
    print("所有记录:{} 数据总条数:{}".format(data,dataCount))

    list = []
    res = []
    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    pageInator = Paginator(list,pageSize)
    context = pageInator.page(pageIndex)
    for item in context:
        res.append(item)
    data = { "code": 0,"msg": "ok","DataCount": dataCount,"data": res }
    return HttpResponse(json.dumps(data))

def search_page(request):
    sql = request.GET.get("hostname")
    data = models.HostDB.objects.all().filter(hostname=sql)
    list = []

    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    data = { "code": 0,"msg": "ok","DataCount": 1,"data": list }
    return HttpResponse(json.dumps(data))

路由层也需要增加搜索接口.

# name: url.py
from django.contrib import admin
from django.urls import path
from MyWeb import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',views.index),
    path('get_page/',views.get_page),
    path('search_page/',views.search_page)
]

添加删除功能: 继续完善删除功能，删除功能就是获取当前表格中的表单ID，然后ajax发后端删除即可。 先来把前端代码改一下.

               data: {"id":obj.data['id']},
               success:function (recv) {
                   layer.msg("删除完成了..", {icon: 6});
               }
           });
            obj.del();
            layer.close(index);
          });
        } else if(obj.event === 'edit'){
          layer.prompt({
            formType: 2
            ,value: data.email
          }, function(value, index){
            obj.update({
              email: value
            });
            layer.close(index);
          });
        }
      });

        // 搜索后的重载
    var $ = layui.$, active = {
        reload: function(){
          var demoReload = $('#demoReload');
          //执行重载
          table.reload('testReload', {
            url:"/search_page",
            page: {
              curr: 1,
              limits: [1]
            }
            ,where: {
                hostname: demoReload.val()
            }
          }, 'data');
        }
      };
    // ---------------------------------------------------------
    // 绑定搜索事件
      $('.demoTable .layui-btn').on('click', function(){
            var type = $(this).data('type');
            active[type] ? active[type].call(this) : '';
          });
    });
    </script>
</body>
</html>

接着修改视图层,增加删除方法的具体实现细节.

from django.shortcuts import render,HttpResponse
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
from MyWeb import models
import json

def index(request):
    return render(request,"index.html")

def get_page(request):
    data = models.HostDB.objects.all()
    dataCount = data.count()
    pageIndex = request.GET.get("pageIndex")
    pageSize = request.GET.get("pageSize")
    print("当前索引:{} 当前大小:{}".format(pageIndex,pageSize))
    print("所有记录:{} 数据总条数:{}".format(data,dataCount))

    list = []
    res = []
    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    pageInator = Paginator(list,pageSize)
    context = pageInator.page(pageIndex)
    for item in context:
        res.append(item)
    data = { "code": 0,"msg": "ok","DataCount": dataCount,"data": res }
    return HttpResponse(json.dumps(data))

def search_page(request):
    sql = request.GET.get("hostname")
    data = models.HostDB.objects.all().filter(hostname=sql)
    list = []

    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    data = { "code": 0,"msg": "ok","DataCount": 1,"data": list }
    return HttpResponse(json.dumps(data))

def delete_page(request):
    get_id = request.GET.get("id")
    models.HostDB.objects.filter(id=get_id).delete()
    return render(request,"index.html")

路由层增加删除视图.

                      success:function (recv) {
                        // 修改完成后,本地直接更新数据,这样就无需刷新一次了

          });
    });
    </script>
</body>
</html>

接着修改视图层，此处只需要增加一个 update_page 函数来实现修改即可。

from django.shortcuts import render,HttpResponse
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
from MyWeb import models
import json

def index(request):
    return render(request,"index.html")

def get_page(request):
    data = models.HostDB.objects.all()
    dataCount = data.count()
    pageIndex = request.GET.get("pageIndex")
    pageSize = request.GET.get("pageSize")
    print("当前索引:{} 当前大小:{}".format(pageIndex,pageSize))
    print("所有记录:{} 数据总条数:{}".format(data,dataCount))

    list = []
    res = []
    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    pageInator = Paginator(list,pageSize)
    context = pageInator.page(pageIndex)
    for item in context:
        res.append(item)
    data = { "code": 0,"msg": "ok","DataCount": dataCount,"data": res }
    return HttpResponse(json.dumps(data))

def search_page(request):
    sql = request.GET.get("hostname")
    data = models.HostDB.objects.all().filter(hostname=sql)
    list = []

    for item in data:
        dict = {}
        dict['id'] = item.id
        dict['hostname'] = item.hostname
        dict['hostaddr'] = item.hostaddr
        dict['hostmode'] = item.hostmode
        list.append(dict)

    data = { "code": 0,"msg": "ok","DataCount": 1,"data": list }
    return HttpResponse(json.dumps(data))

def delete_page(request):
    get_id = request.GET.get("id")
    models.HostDB.objects.filter(id=get_id).delete()
    return render(request,"index.html")

def update_page(request):
    get_id = request.GET.get("id")
    get_hostname = request.GET.get("hostname")
    get_hostaddr = request.GET.get("hostaddr")
    get_hostmode = request.GET.get("hostmode")

    print(get_hostmode)
    obj = models.HostDB.objects.get(id=get_id)
    obj.hostname = get_hostname
    obj.hostaddr = get_hostaddr
    obj.hostmode = get_hostmode
    obj.save()
    return render(request,"index.html")

路由层增加修改接口，方便调用。

# name: url.py
from django.contrib import admin
from django.urls import path
from MyWeb import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',views.index),
    path('get_page/',views.get_page),
    path('search_page/',views.search_page),
    path('delete_page/',views.delete_page),
    path("update_page/",views.update_page)
]
