哪个不是有效的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，比如说：

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

现在，只需提出请求：

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

这就是输出callJson({json-data})。

工作代码段

＆＃13;

$(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);
  });
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

＆＃13;

更正了代码段。检查控制台。
