How Can I Generate Random Colors for a Polyline in JavaScript?

How to Implement a Random Color Generator in a Polyline's Color Property

In the provided code, we aim to replace the static blue color "#0000FF" with a randomly generated color for the polyline's color property.

To achieve this, follow these steps:

Replace the Static Color with getRandomColor()

Inside the document.overlay constructor, replace the "#0000FF" with getRandomColor(), which will generate a random hexadecimal color.

document.overlay = GPolyline.fromEncoded({
    color: getRandomColor(),
    weight: 10,
    points: encoded_points,
    zoomFactor: 32,
    levels: encoded_levels,
    numLevels: 4
});

Function to Generate Random Color

Here's the Javascript function getRandomColor() that generates random hexadecimal colors:

function getRandomColor() {
  var letters = '0123456789ABCDEF';
  var color = '#';
  for (var i = 0; i < 6; i++) {
    color += letters[Math.floor(Math.random() * 16)];
  }
  return color;
}
