ajax 交互问题

routes.php

Route::post('infoclass/up/{id}', 'InfoclassController@up');<br></br>

Controller

public function up(Request $id,$parentid,$orderid)
{    
    echo json_encode(array("status"=>"y","info"=>"排序提升成功"));
}<br></br>

js文件

function Promote(title,id,parentid,orderid)
{
  var title       = title;    
  var id          = id;    
  var parentid    = parentid;    
  var orderid     = orderid;    
  $.ajax({
        type: "POST",        
        dataType: "json",        
        cache: false,        
        url: title+'/up',        
        data: {
            id: id, parentid: parentid, orderid: orderid, _method:"POST"        
        },       
         success: function(data) {
            if(data.status == 'y'){
                layer.msg(data.info, {icon: 1});                location.reload();                        }else{
                layer.msg(data.info, {icon: 2});            }
         }
    })
}
<br></br>

错误：

感觉是路由没有设置好么 - -，想问下哪里出问题了。
