$("#mylocation_status").text('GPS定位完成,' + position.coords.latitude + ',' + position.coords.longitude);
htmlString = "<img src='http://maps.googleapis.com/maps/api/staticmap?";
htmlString = htmlString + "center=" + position.coords.latitude + "," + position.coords.longitude + "&";
htmlString = htmlString + "zoom=15&size=290x360&maptype=roadmap&markers=color:red%7Clabel:S%7C" + position.coords.latitude + "," + position.coords.longitude + "&sensor=false'/>";
