我的代码是：

if(nick.length > 0){
var url='http://api.worldoftanks.ru/2.0/account/list/?application_id=171745d21f7f98fd8878771da1000a31&search='+nick;
$.getJSON(url, function(json) {
$('#result').html('');
$.each(json.data, function(index, data) {
if(index=='0'){
$('#result').append('<p> name: ' + data.nickname+ '</p>');
$('#result').append('<p> ID: ' +data.id+ '</p>');
var id=data.id;
var url2='http://api.worldoftanks.ru/2.0/account/info/?application_id=171745d21f7f98fd8878771da1000a31&account_id='+id;
$.ajax({
type: "GET",
url: url2,
dataType: 'json',
crossDomain: true,
success: function(stats) {
stats = JSON.parse(stats);
$.each(stats.data.id.statistics.all, function(i, all) {
var wins=all.wins;
var losses=all.losses;
$('#result').append('<p>Wins: ' +wins+ '</p>');
$('#result').append('<p>Losses: ' +losses+ '</p>');
});
}
});
}
});
});
}else{
alert('enter username');
}
});
错误是：
Uncaught TypeError: Cannot read property 'statistics' of undefined
$.ajax.success
c
p.fireWith
k
r
我在这里做错了什么？
我是获取json数据的新手，所以请帮助我！谢谢你们！ ：）

你是否在将它用作json对象之前检查是否应首先解析它？ 像这样;
stats = JSON.parse(stats);
$.each(stats.data.eval(id).statistics.all, function(i, all) {
var wins=all.wins;
var losses=all.losses;
$('#result').append('<p>Wins: ' +wins+ '</p>');
$('#result').append('<p>Losses: ' +losses+ '</p>');
});

您没有属性id，您必须使用6217895，但这不是有效的属性名称，因此json似乎无效。
正确的路径是stats.data.6217895.statistics.all，但正如我之前所说，这是无效的，会引发错误。
答案 2 :(得分：1)
您的id可能是dynamic，请尝试此操作，
stats = JSON.parse(stats);
$.each(stats.data, function(i, id){
$(id.statistics.all).each(function(j,all){
var wins=all.wins;
var losses=all.losses;
$('#result').append('<p>Wins: ' +wins+ '</p>');
$('#result').append('<p>Losses: ' +losses+ '</p>');
});
});

如果单个json中有多个id，则@Rohan Kumar代码将起作用。如果你总是得到相同的json，但有不同的id，那么这对你有用：）
stats = JSON.parse(stats);
$.each(stats.data[0].statistics.all, function(i, all) {
var wins=all.wins;
var losses=all.losses;
$('#result').append('<p>Wins: ' +wins+ '</p>');
$('#result').append('<p>Losses: ' +losses+ '</p>');
});
