Attempting to alter the background hue using a variable

Can't Change Color with a Variable, Console Works but Clicking on Square Doesn't

Trying to use a variable named 'Color'.

Even tried using an actual string value that didn't work.

Answer 1

Answer №1

The correct attribute is backgroundColor, not Colour. Make sure not to include an additional u in the word.

Answer 2

The correct attribute is backgroundColor, not Colour. Make sure not to include an additional u in the word.

Answer 3

Answer №2

To correct the code, you should change backgroundColour to backgroundColor without the letter u:

document.getElementById("shapes").style.backgroundColour = colour;
______________________________________________________^

The corrected version should be:

document.getElementById("shapes").style.backgroundColor = colour;

NOTE 1: Remember to trigger the function to see the changes and make sure to assign a width/height to your target div shapes so it is visible.

NOTE 2: It is important to listen for the DOMContentLoaded event to ensure all elements are loaded in the DOM before executing your script.

Example of the corrected code:

<!DOCTYPE html>

<html>

<head>
  <link href="main.css" rel="stylesheet" type="text/css" />
  <style>
    #shapes {
      width: 100px;
      height: 100px;
      border: 1px solid #000;
    }
  </style>
</head>

<body>
  <h1>Test Your Reactions!</h1>
  <p>Click on the shapes as fast as you can</p>
  <div id="shapes">

  </div>
  <script>
    document.addEventListener("DOMContentLoaded", function(event) {
      var shapes = document.getElementById("shapes");
      shapes.addEventListener('click', myFunction, false);
    });

    function myFunction() {
      shapes.style.backgroundColor = "#" + (Math.random() * (1 << 24) | 0).toString(16).slice(-6);
    }
  </script>
</body>

Give this a shot

let element = document.getElementById("element"); // Define once, use multiple times

function changeColor() {
  let newColor = '#'+((Math.random() *(1<<24)|0).toString(16).slice(-6));
  element.style.backgroundColor = newColor;
  console.log(newColor);
}
element.addEventListener('click', changeColor); // Trigger color change on click
