javascript Simple example of web page progress bar

I recently learned new knowledge and encountered a small functional web page progress bar. I found an article that is quite good. I will record it here. , maybe it can help everyone,

Example code:

<!DOCTYPE html>
<html>
<head>
<style>
#box {float:left;width:100%;height:18px;border:1px solid;}
#bar {float:left;width:100%;height:18px;border:0px;background:#00f;}
</style>
</head>
<body>
<p id="box">
<p id="bar"></p>
</p>
<script language="javascript">
var total = 6480; //总数
var curN = 4480; //当前值
function show()
{
 var box = document.getElementById("box");
 var o = document.getElementById("bar");
 o.style.width = ((curN / total) * 200) + &#39;px&#39;; //200是外框的宽度
}
show();
</script>
</body>
</html>

Negation:

<!DOCTYPE html>
<html>
<head>
<style>
#box {float:left;width:200px;height:18px;border:1px solid;}
#bar {float:left;width:100%;height:18px;border:0px;background:#00f;}
</style>
</head>
<body>
<p id="box">
<p id="bar"></p>
</p>
<script language="javascript">
var total = 6480; //总数
var curN = 6400; //当前值
var baseNub = total - curN;
function show()
{
 var box = document.getElementById("box");
 var o = document.getElementById("bar");
 o.style.width = ((baseNub / total) * 200) + &#39;px&#39;; //200是外框的宽度
}
show();
</script>
</body>
</html>
