答案 0 :(得分：2)
你试过吗
dataType: "json",
而不是
dataType: "application/json",
因为你的json代码没有任何问题。
答案 1 :(得分：1)
刚试了一个当地的例子：
$(function(){
$.get('test.php', function(data) {
alert(data.$test);
});
});
test.php是json输出：
<?php header("Content-type: application/json");?>
{
"$test": "test",
"$lala": {
"$rofl": "$copter",
"blubb": "test"
}
}
像魅力一样工作。没有内容类型标题我收到与你相同的错误，因为它只是一个文本而不是json：）
答案 2 :(得分：0)
$不是未定义值的原因，因为它是正确的JSON命名字符。
我相信data.$tracking应该有效。您也可以尝试data['$tracking']
或者尝试data.d.$tracking
同时将dataType设置为'json'，将contentType设置为'application/json'
在我看来，您应该调试此代码并只是跟踪data并找到所有问题。 StackOverflow的成员不应该跟踪我们所有的json-dump并查找错误，很难读取这么多无用的数据。
答案 3 :(得分：0)
我认为你正确地设置了数据类型，因为JSON是正确的。
应该是
dataType: "json"
如documentation中所述。
编辑 - 因为你正在调用另一台服务器，你必须使用jsonp，所以设置：
dataType: "json",
crossDomain: "true"
