JavaScript method charCodeAt()

This section illustrates you the use of JavaScript method charCodeAt(). The charCodeAt() method returns the Unicode of the character at a specified position.

Its syntax is:

string.charCodeAt(index);

An Index should be greater than 0 and less than the length of the string. If you will not specified any index value, it will takes the default value 0.Unicode code points range from 0 to 1,114,111. The charCodeAt() will always return a value that is less than 65,536.

Here is the code:

<html>
<script>
function charcterCode(){
var st=new String("Welcome to this page");
document.write("The Unicode of the character at position 1 is: "+st.charCodeAt(1));
document.write("<br>");
document.write("The Unicode of the character at position 2 is: "+st.charCodeAt(2));
}
</script>
<h2>Use of method charCodeAt()</h2>
<button onclick="charcterCode();">Character Code</button>
</body>
</html>

Output will be displayed as:

On clicking the button you will get the Unicode of the required character:
