jQuery 实现自动获取当前城市天气信息

function findWeather() {
  var cityUrl = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js';
  $.getScript(cityUrl, function(script, textStatus, jqXHR) {
    var citytq = remote_ip_info.city ;// 获取城市
    var url = "http://php.weather.sina.com.cn/iframe/index/w_cl.php?code=js&city=" + citytq + "&day=0&dfc=3";
    $.ajax({
      url : url,
      dataType : "script",
      scriptCharset : "gbk",
      success : function(data) {
        var _w = window.SWther.w[citytq][0];
        var _f= _w.f1+"_0.png";
        if(new Date().getHours() > 17){
           _f= _w.f2+"_1.png";        
        }
        var img = "<img width='16px' height='16px' src='http://i2.sinaimg.cn/dy/main/weather/weatherplugin/wthIco/20_20/" +_f
        + "' />";
        var tq = citytq + " " + img + " " + _w.s1 + " " + _w.t1 + "℃～" + _w.t2 + "℃ " + _w.d1 + _w.p1 + "级";
         
        $('#weather').html(tq);
      }
    });
  });
}
 
findWeather();
