Decimal number to Hex value conversion




We can convert decimal to hexadecimal values in JavaScript by using toString() function. Here is the syntax
variable.toString(radix);
If radix is kept at 16 then the output will be in hexadecimal value. Here is an sample
var n1=12;
document.write (n1.toString(16));
The output of above string is c ( Hex value of 12 )
The input variable must be an integer. So we will use paraseInt() function to convert any input to pure integer value.

We will also use isNan function to check the user input. Here is the script of this demo
<html>
<head>
<title>Demo of decimal to hexadecimal conversion</title>
<script language='JavaScript' type='text/JavaScript'>
<!--
function hex_convt(){
var n1=document.getElementById('t1').value;
if(isNaN(n1)){
document.getElementById("d1").innerHTML=document.getElementById('t1').value + " is not a number ";
}else{
n1=parseInt(n1);
document.getElementById("d1").innerHTML=n1.toString(16);
// Change the toString(16) to toString(8) or toString(2) get Octal and binary conversion
}

}
//-->
</script>

</head>
<body>

<input type=text name=t1 id='t1' size=8>
<input type=button name='SB' value='Change to Hex' onclick="hex_convt()";> 
<div id=d1></div>
