这不是一个有效的JavaScript。函数调用不能以 ?() 开头。相反，我会要求你创建一个使用它的函数，比如：

function callJson (data) {
  alert(data.length);
  console.log(data.length);
}

现在，只需向以下人员提出请求：

http://quanta.net16.net/wordpressnew/test.php?jsoncallback=callJson

这给出了输出，callJson({json-data}).

工作片段

$(function () {
  function callJson (data) {
    alert(data.length);
    console.log(data.length);
  }
  $.getJSON("https://jsonp.afeld.me/?url=http://quanta.net16.net/wordpressnew/test.php?jsoncallback=callJson", function (data) {
    debugger;
  }).fail(function(data) {
    // console.log( data );
    res = data.responseText.trim().replace("callJson(", "");
    res = res.substr(0, res.length-2);
    res = JSON.parse(res);
    console.log(res);
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

更正了代码段。检查控制台。

我没有正确设置跨源资源共享标头
