ajax 增删改查实现

两种方式 post and get

$.post('提交的地址',{'需要的参数'},function(接收返回数据){具体操作});

eg: $.post('admin',{'_token':'fjidsoajfidjsaoig'},function(data){alert(data)});

$.get('提交的地址',function(接收返回数据){具体操作});

eg: $.get('admin',function(data){alert(data)});

具体实例：

<!-- 内容 -->
<div class="col-md-10">
   <!-- 面版 -->
   <div class="panel panel-default">
  
      <table class="table-bordered table table-hover">
         <th><input type="checkBox" name="" id=""></th>
         <th>ID</th>
         <th>NAME</th>
         <th>上次登录时间</th>
         <th>状态</th>
         <th>操作</th>
         @foreach($data as $val)
         <tr>
            <td><input type="checkBox" name="" id=""></td>
            <td>{{ $val->id }}</td>
            <td>{{ $val->name }}</td>
            <td>{{date('Y-m-d H:i:s',$val->time)}}</td>
               @if($val->status)
               <td><span class="btn btn-danger" onclick="statu(this,{{ $val->id }},1)">禁用</span></td>
               @else
               <td><span class="btn btn-success" onclick="statu(this,0)">正常</span></td>
               @endif
            <td><a href="javascript:;" onclick="edit({{ $val->id }})" class="glyphicon glyphicon-pencil" data-toggle="modal" data-target="#editAdmin"></a>&nbsp;&nbsp;&nbsp;<a href="javascript:;" onclick="shanchu(this,{{ $val->id }})" class="glyphicon glyphicon-trash"></a></td>
         </tr>
            @endforeach
      </table>
