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

[Rui Fortes]

TomMallard proposed an even better way:

This works...

parseInt('0xFF')

The 0x means it's a hex number.

      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
