The example in this article describes how to use JavaScript to convert rgb colors into hexadecimal colors. Share it with everyone for your reference. The specific implementation method is as follows: 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>javascript RGB转16进制</title>
</head>
<body>
<script>
function toHexString(r,g,b) {
 return ("00000" + (r << 16 | g << 8 | b).toString(16)).slice(-6);
}
/*
或者：
function RGB2HEX(a,b,c){return"#"+((256+a<<8|b)<<8|c).toString(16).slice(1)}
*/
var hex = toHexString(100, 100, 100);
alert(hex);
</script>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
