javascript - 遍历简单的javascript对象

Question

我有心理障碍。我如何访问从 ajax 函数返回的 javascript 对象内的数据？

我想这样的事情会起作用:

data[0].id would return 1 
data[1].category.description would return "MEN"

帮助将不胜感激!

"[ {
  "id" : 1,
  "description" : "PANTS",
  "price" : 10.99,
  "category" : {
    "id" : 1,
    "description" : "MEN"
  },
  "customerType" : {
    "id" : 1,
    "type" : "COUNTER"
  }
}, {
  "id" : 2,
  "description" : "SHIRT",
  "price" : 4.99,
  "category" : {
    "id" : 1,
    "description" : "MEN"
  },
  "customerType" : {
    "id" : 1,
    "type" : "COUNTER"
  }
} ]"

Answer 1

应该可以，只需循环即可

dataLength=data.length;
for(var i=0;i<dataLength;i++){
    var dataID = data[i].id;
    var dataCatagory = data[i].category.description;
}
