Alert formatted as hexadecimal in JavaScript

Question

How do I alert as FF and not 255 with this:

var myHex1 = 0xff;  
alert(myHex1);//alerts 255


var myVar = 255;
var myHex2 = myVar.toString(16);
alert(myHex2);//also alerts 255 and not FF

Answer 1

Your second example works for me exactly how it is. Are you sure you're alerting the right variable in your test?

Answer 2

Ok it was a string I hadn't parsed to an integer.

Answer 3

And standard compliant approach is:

var x = 0xFF; window.alert(x.toString(16)); //ff
