javascript - 检索 getJSON 属性值

Question

我有以下 JSON 位于 ../JSON/addresses.json:

[
{
"id":"Cheonan2",
"Field1": "96, 3Gongdan1-ro",
"Field2": "Seobuk-gu, Cheonan-si",
"Field3": "Chungcheongnam-do, 31093, Korea",
"Field4": "",
"Field1K": "31093 충청남도 천안시",
"Field2K": "서북구 3공단1로 96",
"Field3K": "",
"Field4K": ""
}
]

使用 $.getJSON 时如何检索“id”属性？我尝试了以下代码，但控制台返回“未定义”错误:

var JSONAddress = $.getJSON("../JSON/addresses.json",function(){ 
console.log(JSONAddress[0].id);})

Answer 1

如果我们假设您的 JSON URL 返回 JSONAddress 数组，那么您应该编写:

   $.getJSON("../JSON/addresses.json",function(JSONAddress){ 
          console.log(JSONAddress[0].id);
  });
