Question

我正在尝试使用jQuery ajax循环遍历json。出于某种原因，它不允许我这样做。我收到了PHP的json和我JSON.stringify它，因为它是给我回来的对象。但是，现在在javascript的for循环中，我需要$ htmlvalue [i]，因为我可以解析数据。

感谢您的帮助。希望我说得对。

PHP文件：

<?php
    $nfl = simplexml_load_file('http://www.nfl.com/liveupdate/scorestrip/ss.xml');


    $items = array();
    foreach ($nfl->gms->g as $game) {
        foreach($game->attributes() as $a => $b) {
            $items[] = $a;
            $items[] = $b;
        }
    }
    echo json_encode($items);
?>

Javascript FILE：

$.ajax({
    type:"post",
     url: "nfl.php",
     dataType: "JSON",
      success: function(response){
          var $data = response,
              $htmlvalue = '';
          $htmlvalue = JSON.stringify($data.length);
          for(i=0; i < $htmlvalue.length; i++){
             console.log('<h4>' +$htmlvalue[i].eid + "</h4>");
          }
      },
      error: function(){
           console.log("error");
      }
  });

服务器响应：

Answer 1

您尝试解析的json不是一种易于解析为混合对象的格式。你提供的JSON是一个混合对象的数组，一些字符串，例如“eid”，有些是对象，例如{“0”：“2014091100”}。您的问题是您试图将数据转换为不合适的格式。数据已经格式化为XML，将数据视为XML，不要尝试将其融入JSON

Answer 2

您必须更改将XML数据转换为JSON数组的方法。现在它不是你试图通过JavaScript处理的格式。

$items = array();
foreach ($nfl->gms->g as $game) {
    $row = array();
    foreach ($game->attributes() as $a => $b) {
        $row[$a] = (string) $b;
    }
    $items[] = $row;
}

echo json_encode($items);

下一步是删除JSON.stringify，因为您希望将响应读作数组，而不是字符串。不应使用JSON.parse，因为您已使用$.ajax在dataType: "JSON"调用中传递了有关响应格式的信息。

如果仍然无效，请在控制台中检查您的回复并在此处提供结果。使用$.each()代替for()也是个好主意，因为读取此数组会更容易。
