我正在尝试使用wunderground的api，Leaflet和Cloudmade将天气图标显示在地图标记中。我已经显示了文本和带有图标图像的变量，但是我不确定如何显示它。这是我的代码：

jQuery(document).ready(function($) {
    $.ajax({
          url: "http://api.wunderground.com/api/cd48ac26fb540679/conditions/q/pws:KCASANFR128.json",
          dataType: "jsonp",
          success: function(parsed_json) {
              var location = parsed_json['current_observation']['observation_location']['city'];
              var temp_f = parsed_json['current_observation']['temp_f'];
              var icon = parsed_json['current_observation']['icon_url'];
              marker1.bindPopup("Current temperature in " +location+ " is: " + temp_f).openPopup();
        }
    });
});

我尝试了一下但没有成功：

marker1.bindPopup( <img src=icon> "Current temperature in " +location+ " is: " + temp_f).openPopup();

有什么建议？
