想要访问＆＃34;原创＆＃34;来自sku列表。但它返回未定义的原始。不确定它出错的地方＆gt;。＆lt;感谢快速帮助

Answer 1

尝试使用json["original"]

进行访问

var json =    {
  "label": "",
  "sku": "true",
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"300.00"
  },
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"350.00"
  },
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"400.00"
  },

  "promo": "",
  "promo-img": "",
  "specs": [],
  "original":"350.00"
}


if(json["original]){
 object += '<div class="original-price">'+ json["original"] +'</div>';

Answer 2

这是访问该属性的简单方法：

var json =    {
  "label": "",
  "sku": "true",
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"300.00"
  },
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"350.00"
  },
  "xxx": {
    "promo": "",
    "specs": [],
    "original":"400.00"
  },

  "promo": "",
  "promo-img": "",
  "specs": [],
  "original":"350.00"
}

var object='';
if(json["original"]){
object += '<div class="original-price">'+ json["original"] +'</div>';
console.log(object);
}
