HTTP xx返回

请教，为什么有的返回JSON可以读，比如下面这个天气预报JSON不能读呢（我自己的用HTTPSERVER返回的JSON也不能读）（返回的是标准JSON）

天气预报JSON :http://t.weather.sojson.com/api/weather/city/101030100

getJSON('http://t.weather.sojson.com/api/weather/city/101030100').then(function(data) {
      alert('Your Json result is:  ' + data); //you can comment this, i used it to debug

      var html = '<ul>';
      for (var i = 0; i < data.length; i++) {
         html += '<li>' + 'jobID is:'+data.low + ', file path is' +data.filePath + '</li>';

      document.getElementById('result').innerHTML = html; //display the result in an HTML element
