title: Loading animation in Google maps infowindow
body: <p>I have developed this <a href="http://weathermap.cloudcontrolled.com/" rel="nofollow">http://weathermap.cloudcontrolled.com/</a> from where you can click on a place and get the current weather details in it. Everything is working properly but its <strong>getting small delay after click on a place to show weather</strong>. For that I would like to show a small <strong>loading animation inside the infowindow</strong> and after the weather data available it will show the weather in the same infowindow. How to do this.
