Accessing JSON elements from javascript
提问by Luis D Urraca
$.getJSON('http://23.21.128.153:3000/api/v1/holidays', function(data){
alert("this: " + data.holiday[0].name);
});
I'm trying to access the "name" attribute of the first element of my JSON response but without success, can anyone tell me what I'm doing wrong.
我正在尝试访问 JSON 响应的第一个元素的“名称”属性，但没有成功，谁能告诉我我做错了什么。

Try this:
尝试这个：
data[0].holiday.name
The datalooks like this:
该data如下所示：
[
{
"holiday":{
"id":1,
"date":"2012-05-01",
"name":"Dia del trabajo",
"description":"",
"country_id":1,
"moved_date":"2012-04-30"
}
},
{
"holiday":{...}
},
...]
So, you need to select the first element from the main array (data[0]), then get its holidayproperty (data[0].holiday), and then get its nameproperty.
因此，您需要从主数组中选择第一个元素 ( data[0])，然后获取其holiday属性 ( data[0].holiday)，然后获取其name属性。
