How Can I Randomize the Color of a Google Maps Overlay?

Randomizing the Color Property in a Google Maps Overlay

Your goal is to enhance the following Google Maps function with a random color generator for the "color" property:

document.overlay = GPolyline.fromEncoded({
    color: "#0000FF",
    weight: 10,
    points: encoded_points,
    zoomFactor: 32,
    levels: encoded_levels,
    numLevels: 4
});
Copy after login

Solution:

To accomplish this, replace the static "#0000FF" hexadecimal value with a call to the getRandomColor() function, which generates a random hex color code:

color: getRandomColor()
Copy after login

Implementation Details:

The getRandomColor() function employs the following algorithm:

  • Defines a set of hexadecimal characters.
  • Iterates six times to create the color code.
  • For each iteration, it appends a random character from the set to the color string.

Example Usage:

In the following example, the getRandomColor() function is applied to a dynamic color pad element:

function getRandomColor() {
  // Generate a random hex color code.
  // ...
}

function setRandomColor() {
  // Set the color of the #colorpad element.
  $("#colorpad").css("background-color", getRandomColor());
}
Copy after login

HTML:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
Copy after login

By incorporating the getRandomColor() function into your Google Maps overlay, you can now assign random colors to your polylines, markers, polygons, and other map elements.
