laravel从JSON响应中获取未定义的对象数据

我使用ajax通过控制器从模型中获取数据，我认为每件事都运行得很好，当我使用console.log（响应）进行检查时，我得到了

Object {buyTemps: Object}

在物体的侧面，我找到了阵列中的所有数据，到目前为止，所有东西都是好的

ajax

     $(".buy-tr").click(function(e){ 
    var 
      data = {}, 
      $row = $(this).closest("tr"),            // Finds the closest row <tr> 
      $tds = $row.find("td:nth-child(1)");     // Finds the 2nd <td> element
    $.each($tds, function() {                  // Visits every single <td> element
        data={buyId:$(this).text()};                     
    }); 
  //  $(this).find('input:radio').prop('checked', true); 
    $(".buy-tr").click(function(e){ 
    var 
      data = {}, 
      $row = $(this).closest("tr"),         // Finds the closest row <tr> 
      $tds = $row.find("td:nth-child(1)");  // Finds the 2nd <td> element
    $.each($tds, function() {               // Visits every single <td> element
        data={buyId:$(this).text()};                     
    });  
    $.ajax({
        url : "/buy/selectTable",
        type : 'GET',
        dataType : 'json',
        data : data,
    success : function(response) { 
            console.log(response);
       $('#buyItem-table tbody').empty();
        $.each(response,function(index, v){
           $('#buyItem-table tbody').append(                                          
                  "<tr><td>"         +  v.buyItemTempId   
                      + "</td><td>"  +  v.itemName    
                      + "</td><td>"  +  v.itemExpire    
                      + "</td><td>"  +  v.buyPrice                          
                      + "</td><td>"  +  v.buyBox   
                      + "</td><td>"  +  v.itemPacking                           
                      + "</td><td>"  +  v.buyQty       
                 + "</td></tr>" );          
           });

    },
    error : function(response) {
      swal("error"); 
    }

在我的控制器

     public function selectItemTable()
    {
        $buyId = Input::get('buyId'); 
        $buyTemps = DB::table('vbuytemp')->where('buyId',$buyId)->paginate(10);      
         return Response::json(compact('buyTemps'));    
}

控制台日志（v）

  Object {total: 1, per_page: 10, current_page: 1, last_page: 1,       next_page_url: null…}current_page: 1data: Array[1]0: Objectbarcode: "08815408"buyBox: 30buyId: 2buyItemTempId: 2buyPrice: "2.500"buyQty: 90itemExpire: "2018-01-04"itemId: 2itemName: "Panadol Extra tab"itemPacking: 2minQty: 1roofId: 1sellingForm: 1__proto__: Objectlength: 1__proto__: Array[0]from: 1last_page: 1next_page_url: nullper_page: 10prev_page_url: nullto: 1total: 1__proto__: Object__defineGetter__: __defineGetter__()__defineSetter__: __defineSetter__()__lookupGetter__: __lookupGetter__()__lookupSetter__: __lookupSetter__()constructor: Object()hasOwnProperty: hasOwnProperty()isPrototypeOf: isPrototypeOf()propertyIsEnumerable: propertyIsEnumerable()toLocaleString: toLocaleString()toString: toString()valueOf: valueOf()get __proto__: get __proto__()set __proto__: set __proto__() 

结果所有表格单元格都填充了未定义的
