How to get the ASCII value in JavaScript for the characters

Question

Convert character to ASCII code in Javascript

my requirement is to get the ASCII value of the alphabet letters... Can anyone suggest how to do this in JavaScript?

Solution 1

Here is the example:

var charCode = "a".charCodeAt(0);
console.log(charCode);

Or if you have longer strings:

var string = "Some string";

for (var i = 0; i < string.length; i++) {
  console.log(string.charCodeAt(i));
}

String.charCodeAt(x) method will return ASCII character code at a given position.

Solution 2

you can try

"str".charCodeAt(0)

This is Unicode, not ASCII!!! w3schools.com/jsref/jsref_charcodeat.asp

@Andrew ASCII is a subset of Unicode, so it's actually the same in this case. (Actually, Unicode is not an encoding, and ASCII is, so in that sense they are different. But for the purposes of charCodeAt, there's no difference).

This won't work. it will take only 's'
