返回的数据为marketlivedata(...)。这是在调用marketlivedata未在脚本中定义的函数。由于将dataType用作jsonp，因此将执行该函数。

为了解决这个问题，您可以更改JSON服务器中的数据格式（这看起来像第三方服务，因此可能无法实现），也可以定义该名称的函数，当响应到达时将调用该函数。

function getUserData() {

  $.ajax({

    type: "GET",

    url: "http://mobilelivefeeds.indiatimes.com/homepagedatanew.json",

    dataType: 'jsonp',

    crossDomain: true,

    success: function(data) {

      //  $('#ajexLoaderSec').hide();

      console.log(data);



    },

    error: function(e) {

      console.log(e);

    }

  });

};

getUserData();





function marketlivedata(data) {

  console.log(data);

}
