Hi all, Thanks for your replies.
But why do a for..in on a Number?
I was just testing scopes of the variables in JS.
This was just something ridiculous and so asked why?
BTW, I'm not in search of how to make for-in loop work, but in search of what is the "toColorPart" string which i got while testing them in firebug1.5.3 installed in FF3.8.
Thanks again for all your replies.
Regards,
Srini

Are you using Prototype? Prototype add properties to Number objects
(http://www.prototypejs.org/api/number). Since for in loops through
all the properties of an object, it will go through each of those
methods, including toColorPart.
By the way, I don't think your use of the for in loop is appropriate
here. For in is for looping through objects:
var obj = new Object();
obj.prop1 = 'a';
obj.prop2 = 'b';
for (var x in obj) {
alert(x); // "prop1", "prop2"
alert(obj[x] ); // "a", "b"
}
Are you looking for the plain for loop: for (var x = 3; x < 20; x++) { ... }
