Is there a way to click on a button and have its background color change randomly each time?

Question

Is there a way to click on a button and have its background color change randomly each time?

I am facing an issue with a button on my HTML page. When the button is clicked, I want its background color to change to a random different color. However, despite trying various sources, I am unable to get it right. It seems like I am not placing the code correctly.

**JS:**
var randomColor = Math.floor(Math.random()*16777215).toString(16);
document.getElementsById("mainButton").style.background = randomColor;


**HTML:**
<button id="mainButton">click</button>

**CSS:**
#mainButton{
  background-color: white;
  font-family: monospace;
  border: none;
  width: 100%;
  height: 100%;
  position: absolute;
  right: 0;
  top: 0;
}

I would appreciate any guidance or tips that could help me solve this issue. Thank you!

Answer №1

There are a few mistakes that need correction:

1) It should be getElementById instead of getElementsById.

2) Instead of directly setting the style property, you should set style.backgroundColor

3) The randomColor variable will generate a hex value, so remember to add '#' at the beginning.

Here is an example with the corrections made

var randomColor = Math.floor(Math.random()*16777215).toString(16);
document.getElementById("mainButton").style.backgroundColor = '#' + randomColor;

#mainButton{
  background-color: white;
  font-family: monospace;
  border: none;
  width: 100%;
  height: 100%;
  position: absolute;
  right: 0;
  top: 0;
}

<button id="mainButton">click</button>

const button = document.getElementsByTagName('button')[0];

function randomBackgroundColorChange (e) {
  button.style.backgroundColor = '#'+Math.floor(Math.random()*16777215).toString(16);
}

button.addEventListener("click", randomBackgroundColorChange);
window.onload = randomBackgroundColorChange();

button {
  display:block;
  margin:auto;
  height:35px;
  width:95%;
  text-shadow:1px 1px 0.5px #000;
  border:solid 1px #000;
  font-size:18px;
  color:#ccc;
  cursor:pointer;
}

If you're interested in learning how to create a random color using JavaScript, there's a helpful demo available on W3Schools:

Instead of changing the body background color as shown in the demo, you can modify it to change the color of a button. Here's an example:

const myBtn = document.getElementByID("mybutton");
myBtn.style.backgroundColor = bgColor;
