Loop via json

Question

Я пытаюсь выполнить json с jQuery ajax. По какой-то причине это не позволяет мне это делать. Я получил json от PHP, и я JSON.stringify, потому что он возвращал мне объекты. Но теперь в цикле for в javascript мне нужно $ htmlvalue [i], чтобы я мог анализировать данные.

Спасибо за помощь. Надеюсь, я описал это право.

PHP FILE:

<?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"); 
     } 
    });

Answer 1

Вы должны изменить способ преобразования данных XML в массив JSON. Теперь это не в формате, который вы пытаетесь обработать своим JavaScript.

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

echo json_encode($items); 

Следующий шаг удаляет JSON.stringify, потому что вы хотите прочитать свой ответ как массив, а не как строку. Использование JSON.parse не требуется, потому что вы уже передали информацию о формате ответа в $.ajax, используя dataType: "JSON".

Если он по-прежнему не работает, проверьте свой ответ на консоли и дайте результаты здесь. Было бы также полезно использовать $.each() вместо for(), так как будет проще читать этот массив.

Answer 2

JSON вы пытаетесь разобрать не в формате, который легко интерпретируемое в меняющие объекты. JSON, который вы предоставили, представляет собой массив смешанных объектов, некоторые строки, например. «eid», а некоторые - объекты, например. {"0": "2014091100"}. Ваша проблема заключается в том, что вы пытаетесь выталкивать данные в формат, который не подходит. Данные уже отформатированы, так как это XML, обрабатывают данные как XML и не пытаются и вымывают их в JSON.
