layui实现动态和静态分页

开发管理后台是每一个开发人员都要熟悉的一个环节，作为后端程序员，公司的所有机密数据都掌握在我们手上，所以这个时候，如果不是公司的核心成员，是不能接触到某些数据的，这个时候所有的工作都落到了我们的手上，从PS到Linux都需要我们亲历亲为，还好发现了layui这个前端框架，很大程度上减轻了我们的压力．

今天我们先来学习一下layui实现动态数据表，静态数据表，以及表格的分页，其中还涉及到动态刷新数据表,数据表工具栏使用,表单提交等功能，这个静态分页同样适用在信息类网站,我的工作开发环境是debian桌面版，所以所有的实验也是在debian基础上测试

实现过程

业务逻辑我都写到注释里面了，这样大家也友好一些，避免一会看代码，一会看说明容易分神

后端php代码

order.php(订单控制器,部分业务代码不用太深究）

  // 订单列表
  public function orderList()
  {
    // 动态渲染前台表格
    $operating = $this->request->getPost('getlist', 'trim');
    // 首次这里不会执行，数据表开始渲染的时候才会请求以下部分
    if ('orderlist' === $operating) {
      // 进行分页查询
      $page = $this->request->getPost('page', 'intval', 1);
      $limit = $this->request->getPost('limit', 'intval', 10);
      $start = ($page - 1) * $limit;

      // 如果有其他条件查询在这里可以带上
      $merchant_no = $this->request->getPost('merchant_no', 'trim', '');
      $order_no = $this->request->getPost('order_no', 'trim', '');
      $start_time = $this->request->getPost('start_time', 'trim', date("Y-m-d H:i:s", strtotime("-1 day")));
      $end_time = $this->request->getPost('end_time', 'trim', date("Y-m-d H:i:s"), time());

      // 获取符合条件的记录数量
      if($GLOBALS['SESSION']['admin_group_id'] >1){
        $merchant_no = $GLOBALS['SESSION']['admin_username'];
      }
      $order_nums = orders::getItemNums($merchant_no, $order_no, $start_time, $end_time);

      // 分页进行查询条件记录
      $order_list = orders::getItem($merchant_no, $order_no, $start_time, $end_time, $start, $limit);
      $datas = ['code' => 0, 'msg' => ''];
      // 将总的记录条数传给前台进行渲染分页
      $datas['count'] = $order_nums;
      // 重新过滤一遍数据，很多没有用到的不能全部发给试图，尤其是动态渲染的，很容易暴露，建议加工一下再传
      foreach ($order_list as $k => $v) {
        $order_list[$k]['orderno'] = $v['order_id'];
        $order_list[$k]['user_orderno'] = $v['order_no'];
        $order_list[$k]['username'] = $v['merchant_no'];

      }

      $datas['data'] = $order_list;
      echo json_encode($datas);
      safe_exit();
    }
    // 首次先现实模板页
    self::$view->render('orders_orderlist');

表格模块：http://www.layui.com/doc/modules/table.html

调试的时候可以打开chrome,firefox 的 console 和 network进行查看，仔细研究分析

数据表工具条事件

工具栏是指在行单元格内可以操作对应的行，因为使用layui的元素监听，很容易就获取到相应对应整行的数据.

比如获取表单的数据,只需要监听表单提交事件，直接就可以一次获取到所有的参数和值：

<script>
  layui.use(['form','jquery'],function(){
    let form = layui.form,
      $ = layui.$;
    form.on('submit(fuck-submit)', function(data){
      if(data.field.password && data.field.password.length < 5){
        layer.msg('密码不能小于５位');
        return false;
      }
      $.post('index.php?&a=adminEdit&op=update&uid='+data.field.uid,{
          username:data.field.username,
          password:data.field.password,
          level:data.field.level,
          is_enabled:data.field.is_enabled
        }, function(responseText){
          //console.log(responseText);
          if(responseText.errno === 8){
            layer.msg(responseText.errstr,{icon:6});
            return false;
          } else {
            layer.msg(responseText.errstr,{icon:5});
            location.reload();
          }
        },'json'
      );
      return false;
    });
  });
</script>

这里是官方文档的：

form.on('submit(*)', function(data){
 console.log(data.elem) //被执行事件的元素DOM对象，一般为button对象
 console.log(data.form) //被执行提交的form对象，一般在存在form标签时才会返回
 console.log(data.field) //当前容器的全部表单字段，名值对形式：{name: value}
 return false; //阻止表单跳转。如果需要表单跳转，去掉这段即可。
});

我们今天要操作的数据表也是要采用这种方式，首先我们看看看怎样生成和渲染出工具条：

只需要在body部分插入一个容器,注意这里的javascript的type是text/html,这个是供layui解析用的，在这里的d也就是我们在渲染表格的时候的数据,所有的字段的值都可以在这个d里面获取到

<table class="layui-hide" lay-filter="fucktest" id="test"></table>
  <script type="text/html" id="barDemo">
    <a class="layui-btn layui-btn-xs" user_id="{{d.admin_id}}" lay-event="edit">编辑</a>
  </script>
