Javascript jQuery：从json响应获取订单id

我想获取json响应的值。我编写了一个Ajax函数，如下所示：

$.ajax({
    url: '/v1/shopify-Ajax/ajax.php',
    method: 'post',
    data: {datalog: dataLog, variant: $('#prod').val()}
    })
    .success(function(response){
    //window.location.href = "/v1/thank-you.php";
})

{"order":
    {"id":303657910281,
     "email":"test20@code1.com",
     "closed_at":null,
     "created_at":"2018-03-19T01:04:58-07:00",
     "updated_at":"2018-03-19T01:04:58-07:00",
     "number":811,
     "note":null,
     "token":"9709d7c295ac1dbbaf29c2d09a9d5a9d",
     "gateway":"",
     "test":false,

     "currency":"USD",
     "financial_status":"paid",
     "confirmed":true,          
     "total_discounts":"0.00",

我从服务器端脚本获得如下响应：

$.ajax({
    url: '/v1/shopify-Ajax/ajax.php',
    method: 'post',
    data: {datalog: dataLog, variant: $('#prod').val()}
    })
    .success(function(response){
    //window.location.href = "/v1/thank-you.php";
})

我的问题是，如何直接访问订单id（无循环）并检查订单id是否为null或空白

---

!

如果

response

是字符串，则可能需要对其进行解析，否则可以直接读取值

如果

console.log

显示了一个可以扩展的对象（在开发者工具控制台中），只需使用

如果这不起作用，或者你确定这是一个字符串使用

var responseObj = JSON.parse(response);
var id = responseObj.order.id;

---

在执行

response.order.id

之前，需要确保将

response

解析为对象

提及

dataType : "json"

i、 e

---

在AJAX成功的过程中，您需要解码JSON

var data = $.parseJSON(response);
alert(data.order.id); //you will get order id

---

response.order.id

？我尝试了-response.order.id

var obj=JSON.parse（response）；console.log（obj.order.id）

可能是字符串？然后，

（JSON.parse（response））.order.id

@Jamiec-是！我使用var responseObj=JSON.parse（response）；而且效果很好。
