如何從複雜json訪問元素

-1

hello 從2-3天開始，iam陷入了一個新問題，實際上我必須使用'api url'來檢索複雜的json數組，它就像這樣 -如何從複雜json訪問元素

{"response":{"success":true,"result":{"id":"45203511","device_id":"62970","message":"Rs. 20.00 refunded in your Paytm wallet for your order on Paytm. Updated balance:Rs. 20.0. Queries? Visit Paytm.com\/care.","status":"received","send_at":0,"queued_at":0,"sent_at":0,"delivered_at":0,"expires_at":0,"canceled_at":0,"failed_at":0,"received_at":1507375388,"error":"N\/A","created_at":1507375388,"contact":{"id":"9209301","name":"VK-IPAYTM","number":"VK-IPAYTM"}}},"status":200}

我想從此json打印一個元素到控制檯「console.log（data）;」此代碼在控制檯中打印整個數組，但我必須僅打印「id」元素。請幫助我！

「我只打印‘身份證’元素」

你的數據是嵌套對象，因此要獲得任何對象的屬性，你可以做object.property或object["property"]。這裏是一個例子，如何讓id屬性：

var obj = {"response":{"success":true,"result":{"id":"45203511","device_id":"62970","message":"Rs. 20.00 refunded in your Paytm wallet for your order on Paytm. Updated balance:Rs. 20.0. Queries? Visit Paytm.com/care.","status":"received","send_at":0,"queued_at":0,"sent_at":0,"delivered_at":0,"expires_at":0,"canceled_at":0,"failed_at":0,"received_at":1507375388,"error":"N/A","created_at":1507375388,"contact":{"id":"9209301","name":"VK-IPAYTM","number":"VK-IPAYTM"}}},"status":200} 
 
console.log(obj.response.result.id)

**它顯示的錯誤： - ** _train2.php：23遺漏的類型錯誤：無法讀取屬性 '結果' undefined at Object.fireWith [as resolveWith]（jquery.min.js：2） at A（jquery.min）Object.success（train2.php：23） at i（jquery.min.js：2） .js：4） at XMLHttpRequest。（jquery.min.js：4）_ **我的整個腳本部分是： - ** '' **請幫幫我！** –

@Kalpitrathore，你忘了使用JSON.parse（yourJSONHere）解析你的JSON嗎？ https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse –
