【英文标题】：jQuery: get order id from json response [duplicate]

【发布时间】：2018-08-27 17:48:20

【问题描述】：

我想获取 json 响应的值。我写了一个Ajax函数如下：

$.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";
)

我从服务器端脚本得到响应如下：

"order":
    "id":303657910281,
     "email":"[e-mail]",
     "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":"",

我的问题是，如何直接访问订单 ID（无循环）并检查订单 ID 是否为空或空白。

！

【问题讨论】：

response.order.id ?

我试过了 - 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

【参考方案1】：

如果response是字符串，可能需要解析，否则可以直接读取值。

如果console.log 显示一个您可以展开的对象（在开发者工具控制台中），只需使用

var id = response.order.id;

如果这不起作用，或者你确定它是一个字符串使用

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

【讨论】：

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

【参考方案2】：

在您的 AJAX 成功中，您需要解码 JSON。

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

【参考方案3】：

你需要确保response在做response.order.id之前被解析成一个对象

提及

dataType : "json"

即

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