如何獲取此JSONP供稿進行更新？

Question

我正在嘗試在網頁的div中用$＆ajax顯示JSONP數據。 我希望該數據定期更新。 但是下面的代碼僅顯示一次數據，然后永遠不變。 我應該怎么做才能顯示數據，然后在Feed中的信息發生更改時實際進行更改？

<script type = "text/javascript">
   setInterval(function refreshWeather() { 
   $(function() {
   $.ajax({
   url : "http://api.wunderground.com/api/mykey/conditions/forecast/q/autoip.json",
   dataType : "jsonp",
   success : function(parsed_json) { 
   var temp_f = parsed_json['current_observation']['temp_f'];
   var feelslike = parsed_json['current_observation']['feelslike_f'];
   var forecast = parsed_json['forecast']['txt_forecast']['date'];
   $('#content13').replaceWith(temp_f + " feels like " + feelslike);
     }
    });
    });
   }, 90000);

  </script>

這似乎可行：

$(function () {
    var refreshWeather = function () {
        $.ajax({
            url: "http://api.wunderground.com/api/mykey/conditions/forecast/q/autoip.json",
            dataType: "jsonp",
            success: function (parsed_json) {
                var temp_f = parsed_json['current_observation']['temp_f'];
                var feelslike = parsed_json['current_observation']['feelslike_f'];
                var forecast = parsed_json['forecast']['txt_forecast']['date'];
                $('#content13').replaceWith(temp_f + " feels like " + feelslike);
            }
        });
    };

    refreshWeather();
    setInterval(refreshWeather, 90000);
});
