JSON响应不显示任何

Question

我有如下控制器api_show_employees()：

function api_show_employees() { 
     $this->autoRender = false; 
     Configure::write("debug",0); 
     $office_id = ''; 
     $cond = ''; 
     if(isset($_GET['office_id']) && $_GET['office_id'] != '') { 
     $office_id = $_GET['office_id']; 
     $cond['EmployeePersonal.office_id'] = $office_id; 
     } 

     $order = 'EmployeePersonal.name'; 
     $employee = $this->EmployeePersonal->find('all',array('order' => $order,'conditions'=>$cond)); 
     return json_encode($employee); 
    } 

而且从那里我打电话了AJAX的CTP文件是：

function populate_list(office_id) { 

    var data = ''; 
    data = 'office_id='+office_id; 
    var url_to_call = ''; 
    url_to_call = '<?php echo $this->Html->url(array("controller" => "employee_personals","action" => "api_show_employees")); ?>'; 

    $.ajax({ 
    type : "GET", 
    url : url_to_call, 
    data : data, 
    dataType : "json", 
    error: function (resp){ 
     alert('Something went wrong :('); 
    }, 
    success: function(resp) { 
    alert(resp);  
    //render_ui(resp); 
    } 
    }); 

} 

当我在检查浏览器，我得到的回应是：

我没有ajax选中jsfiddle，我a将警报作为[对象对象]，[对象对象]。

你在JSON响应阵列，使得第一上响应施加循环，然后如图中下面的例子得到的值：

$.ajax({ 
    type : "GET", 
    url : url_to_call, 
    data : data, 
    dataType : "json", 
    error: function (resp){ 
     alert('Something went wrong :('); 
    }, 
    success: function(resp) { 
    for (var i=0; i<resp.length; i++) { 
    alert(resp[i].EmployeePersonal.id); // you will get id 
    alert(resp[i].present_district.name); // you will get district name  
    // so on... 
    } 
    } 
    });
