Equivalent Javascript function

What’s the Javascript equivalent of the VB function Asc() ?. All literature I checked points to fromCharCode() but if I insert an appropriate number as argument, the function won’t return a valid character. Thanks in advance.

fromCharCode is the correct function to use.

If you enter the following in a web page, the result is abc:

document.write(String.fromCharCode(97,98,99));

(Working example)

I don’t know JavaScript, but fromCharCode seems to be more or less related to Chr. The function related to Asc is probably charCodeAt:

function charCodeAtTest(n){
var str = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”; //Initialize variable.
return str.charCodeAt(n – 1); //Return Unicode value of the n-th character.
}

Hi Raul

You could use the unescape() method to convert a Hexadecimal value to its ASCII equivalent

var escapedVal=”%40″;

var escapedVal=unescape(escapedVal);

document.write(‘The escapedVal value (‘ + escapedVal + “) “);
document.write (“evaluates to ” + unescapedVal);

You can write up the method so that the escapedVal becomes variable you will get a document write
