关于php：使用JQuery解析嵌套的JSON

Parse Nested JSON With JQuery

我是JSON的新手，真的很为此苦苦挣扎。我已经阅读了无数其他文章和网页，但似乎无法弄清楚。

我正在使用PHP通过以下代码输出JSON(来自数据库中的数据)：

1 2	header('Content-type: application/json'); echo json_encode($data);

这是JSON：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

25
26
27
28
29

{
"x0": {
"id":"1",
"name":"Rob",
"online":"1",
"gender":"m",
"age":"29",
"height":"5'8''",
"build":"Average",
"ethnicity":"White",
"description":"Art geek person",
"looking_for":"Anything",
"image":"4fs5d43f5s4d3f544sdf.jpg",
"last_active":"29-06-11-1810",
"town":"Manchester",
"country":"UK",
"distance": 0.050973560712308
},
"x1": {
"id":"2",
"name":"Dave",
"online":"1",
"gender":"m",
"age":"29",
"height":"5'8''",
"build":"Average",
"ethnicity":"White",
"description":"Art geek person",
"looking_for":"Anything",
"image":"4fs5d43f5s4d3f544sdf.jpg",
"last_active":"29-06-11-1810",
"town":"Manchester",
"country":"UK",
"distance": 0.050973560712308
}
}

我认为我遇到的问题是JSON是嵌套的(在那里可能是错误的)吗？

这是JQuery：

1
2
3
4
5
6
7
8
9
10
11
12

function fetchProfiles() {
var url='http://url.com/here';
var i = 0;
var handle = 'x'.i;

$.getJSON(url,function(json){
$.each(json.results,function(i,profile){
$("#profiles").append('<p><img src="'+profile.handle.image+'" widt="48" height="48" />'+profile.handle.name+'</p>');
i++;
});
});
}

任何想法或建议表示赞赏！

谢谢！
