getting ASCII code

**xiaawan** · Sep 20, 2007, 23:25

Hi All,
Is there anyway we can get any character's ASCII code.

Code JavaScript:

var hi = "Hi";
alert(hi.charCodeAt(0)); // Shows '72'

Strictly speaking, that's not an ASCII code, unless you give it a character in the 0-127 range. charCodeAt() returns the unicode codepoint (Which incidentally is a superset of ISO-8859-1, if I'm not mistaken). Try this:

Code:

alert("闻".charCodeAt(0));

Thank you guys for your replies. Could you please tell me what is the difference between Unicode and ASCII code?

**AutisticCuckoo** · Sep 21, 2007, 01:56

ASCII is a subset of Unicode. See The Definitive Guide to Web Character Encoding for details.
