Very simple 1 paragraph of background color changes at the moment of the code
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
#dv {width: 100px;height: 100px;}
</style>
</head>
<script>
window.onload=function(){
var oDv = document.getElementById('dv');
oDv.style.backgroundColor='red'
setInterval(function(){
var arrRandNumber = [
getRandomNumber(0,255),
getRandomNumber(0,255),
getRandomNumber(0,255)
];
oDv.style.backgroundColor='rgb('+arrRandNumber[0]+','+arrRandNumber[1]+','+arrRandNumber[2]+')'
function getRandomNumber(rMin,rMax){
var cha = rMax-rMin;
var rand = Math.random();
//return (rMin+Math.round(cha*rand))
}
},500)
//alert(getRandomNumber(0,255))
};
</script>
<body>
<div id="dv"></div>
</body>
</html>
That's all I want to share with you in this article. I hope it will help you learn to use javascript.
