遍歷JSON響應給出了不確定

這JSON響應遍歷JSON響應給出了不確定

{ 
"phweb":{ 
    "cpu":"34.8", 
    "ram":"30.5", 
    "hdd":"42.9",

    "sqlstat":"0", 
    "sqlup":"109 days, 21 hours, 3 minutes and 0 seconds" 
    } 
}

和IM試圖在循環播放，並得到我想要的價值。

success: function(response){ 
    $.each(response.phweb, function(index, value){ 
     alert(value.cpu); 
    }); 
}

但它給了我'未定義'。任何想法，幫助，線索？

您從JSON，不包含任何對象隻字符串有遍歷第一個對象。更改response.phweb到response。

var response = {

UPDATE：如果你想從phwebcpu值，那麼就沒有必要$.each()~ just use response.phweb.cpu`

不錯，但我想只得到 'CPU'，從 'phweb'，任何想法的價值？我不想太循環到'cpu'的所有價值。 –

@CodeDemon：那麼就使用'response.phweb.cpu' –

和怎麼樣我想僅環在「phweb唐代得到了「CPU」值，以及該JSON陣列中的其他具體的價值？ –

例如： -

$.each(response.phweb, function(index,value){ 
      console.log(index + " : " + value); 
     //alert(index.cpu); 
     });
