Question

I am trying to populate infowindow content from an array:

How do I prevent the comma from being printed within the infoWindow?

Answer 1

You can use the .join() method to change your concatenation default char that is the comma

var arrayTest = ["a", "b"];
infoWindow.setContent("<p>Header</p>" + arrayTest.map(function (val) { return "<p>" + val + "</p>" }).join(""));
infoWindow.open(map, marker);
