JavaScript FromCharCode

by

The JavaScript FromCharCode function is one of the String Functions, which is used to convert the Unicode values to string values (based on ASCII Table). The syntax of the JavaScript FromCharCode function is:

String.fromCharCode(ASCII_Value)

NOTE: The FromCharCode() function is a static function of string objects. So, we have to use the String Object while calling this function. For example, String.fromCharCode(109)

JavaScript FromCharCode Example

The following set of examples will help you understand the FromCharCode function.

<!DOCTYPE html>
<html>
<head>
    <title> JavaScript FromCharCode() </title>
</head>
<body>
    <h1> JavaScript FromCharCode </h1>
    <p id= "Content1">Content 1</p>
    <p id= "Content2">Content 2</p>
    <p id= "Content3">Content 3</p>
    <p id= "Content4">Content 3</p>
<script>
  var Str1 = String.fromCharCode(84,117,116,111,114,105,97,108);
  var Str2 = String.fromCharCode(71,97,116,101,119,97,121);
  
  document.getElementById("Content1").innerHTML =  String.fromCharCode(65);
  document.getElementById("Content2").innerHTML =  String.fromCharCode(97);
  document.getElementById("Content3").innerHTML =  Str1;
  document.getElementById("Content4").innerHTML =  Str2; 

</script>
</body>
</html>

OUTPUT

JavaScript FromChatCode Function

ANALYSIS

Within the Script tag, the following statement will find the character at ASCII value 65.

document.getElementById("Content1").innerHTML =  String.fromCharCode(65);

The following JS FromCharCode statement will find the character at ASCII value 97.

document.getElementById("Content2").innerHTML =  String.fromCharCode(97);

The following statements will create a word by grouping multiple ASCII numbers in one function

 var Str1 = String.fromCharCode(84,117,116,111,114,105,97,108);
 var Str2 = String.fromCharCode(71,97,116,101,119,97,121);
