How to generate random numbers in JS (detailed tutorial)
We often use random numbers when making web pages or small programs. The author has compiled a very simple JS program to generate random numbers. Let’s learn together.
Let’s first take a look at the renderings of this source code
You can use it flexibly, we will share the specific JS code with you:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Document</title>
<style>
#count{
font-size: 20px;
color: green;
width: 400px;
height: 30px;
border: 1px solid black;
margin: auto;
line-height: 30px;
text-align: center;
}
</style>
</head>
<body>
<p id="count"></p>
<script>
//产生随机数
function count (){
var i=Math.random()*(999999-100000)+100000;
var j=parseInt(i,10);
j="100000-999999随机产生："+j;
document.getElementById("count").innerHTML= j;
}
setInterval("count()",100);
</script>
</body>
</html>The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
