Its an interesting subject that how one can change the content of google map’s infowindow dynamically. Many times we need to perform an action which results in change of content of infowindow also.
For example, if we have displayed a like button for a particular place which is showing in the content, and its marker is also showing in map. On clicking on that marker, infowindow will launch. Infowindow will also have the same like button. If user clicks on like button of place which is showing in content then we may need to change the style or text of infowindow’s like button also, whenever infowindow will be launched, to show that it is liked now.
