I am attempting a simple random background color generator. When a user clicks the button, the background color changes to a random RGB value. However, I also want the button itself to change to that random color when clicked.
I tried putting DOM manipulators in the event listener and in the random RGB function. However I keep getting this error message:
script.js:19 Uncaught TypeError: Cannot set property 'backgroundColor' of undefined
at randomBgColor (script.js:19)
at HTMLButtonElement.<anonymous> (script.js:7)
randomBgColor @ script.js:19
(anonymous) @ script.js:7
The code is as follows:
<html>
<button id="press" class="button">Press me to change the background color!</button>
</html>
var changeColor = document.getElementById("press");
var button = document.getElementsByClassName("button");
changeColor.addEventListener("click", function(){
randomBgColor();
})
function randomBgColor() {
var x = Math.floor(Math.random() * 256);
var y = Math.floor(Math.random() * 256);
var z = Math.floor(Math.random() * 256);
var bgColor = 'rgb(' + x + ',' + y + ',' + z + ')';
console.log(bgColor);
document.body.style.background = bgColor;
button.style.backgroundColor = bgColor;
}
