PHP，JS創建JSON數據

Question

在PHP我有這樣的事情：

$i=1; 
foreach ($result as $row){ 
    $outp['fields'][$i]['id']=$row['id']; 
    $outp['fields'][$i]['x']=$row['x']; 
    $outp['fields'][$i]['y']=$row['y']; 
    $outp['fields'][$i]['type']=$row['type']; 
    $i++; 
} 
echo json_encode($outp) 

而在JS：

success: function(data) { 
    var map = eval('(data)'); 
} 

這裏是JSON輸出：

{"fields": 
    {"1":{"id":9521,"x":21,"y":96,"type":2}, 
     "2":{"id":9522,"x":22,"y":96,"type":3}, 
     "3":{"id":9523,"x":23,"y":96,"type":1}, 
     "4":{"id":9930,"x":30,"y":100,"type":3} 
    } 
} 

我想爲每個字段編寫html代碼（在這種情況下是4個字段）。 我該怎麼辦？這可能將var地圖轉換爲數組？

感謝

試試這個：

for(var i=1;i<=Object.keys(map["fields"]).length;i++){ 
    console.log(map["fields"][i]["id"]); //id 
    console.log(map["fields"][i]["x"]); //x 
    console.log(map["fields"][i]["y"]); //y 
}
