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

[Peter Brunone]

    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
