[Javascript] How do I convert "FF" to 255?

[TomMallard]

This works...

parseInt('0xFF')

The 0x means it's a hex number.

    Unfortunately, upon closer examination, I see that this doesn't do jack.

      According to the Netscape JavaScript reference, you can use
escape(var) to get the hexadecimal value, and unescape(var) to get the
decimal value.

    Hello.

    How can I get an highlighted version of a color.
    That is, how can I find the code of a color wich is a lighter version of
another color.
    I tryed to do this myself but I need, for instance, to know how to get a
number from a string representing an hexadecimal number.
    I could then add some value to RGB components and use RGB(newred,
newgreen, newblue) to get that color.
    I found Hex function that returns a string representing the hexadecimal
convertion of a number.
    Is there an inverse function to turn a string into a number?
    Something like afunc("FF") that returns 255.

    Thanks
