遍歷JSON從jQuery的的getJSON

Question

下面是代碼：

 $.getJSON(base_url + '/ajax/sortListings.php', { sort: sort }, function(data) { 
      $.each(data, function(i, json) { 

       $('#listings').append($('<div>').load(base_url + '/partialviews/listingAdminPrev.php', { 
        id: json.id, 
        name: json.name, 
        logo: encodeURIComponent(json.logo), 
        address: json.address, 
        city: json.city, 
        state: json.state, 
        zip: json.zip, 
        phone: json.phone, 
        email: json.email, 
        web_link: encodeURIComponent(json.web_link), 
        services: json.services, 
        category: json.category, 
        status: json.status, 
        created: json.created 
       })); 

      }); 
     }); 

當我手動去到sortListings.php文件，並打開$ _ POST變量$ _GET，它工作正常。所以文件沒什麼問題。但在這裏它是無論如何：

include_once('../../app/scripts/config.php'); 
$listingObject = Listing::getInstance(); 

$results = $listingObject->get_listings($_POST['sort']); 

echo json_encode($results); 

該文件將返回此：

也就是5家上市..所以它拉低數據的罰款。然而，除了$ .each（）之外，沒有什麼可以工作的。我甚至嘗試過提醒事情，但沒有任何事情。

沒有控制檯錯誤拋出..

Answer 1

你遇到了你的問題。您期待$_POST中的sort參數，而您正在調用執行GET的getJSON()。

決定是否使用GET或POST並保持一致。

我的猜測是你還需要在Listing::get_listings()方法中提供更好的錯誤處理方法，以便在您沒有獲得預期傳遞給它的數據時提供有用的錯誤。
