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

Mon Apr 23 10:14:34 CDT 2001

Rui,

    We're glad you got the problem worked out... but everybody gets the messages you send to the list, so you only need to send them once (and we all saw Tom's message already, since it was also sent to the list).

Cheers,

Peter

  TomMallard proposed an even better way:

  This works...

  parseInt('0xFF')

  The 0x means it's a hex number.

    Modify this:

    <<HTML>
    <<HEAD>
    <<TITLE>Numbers Conversion Table</TITLE>
    <</HEAD>

    <<BODY>
    <<B>Using toString() to convert to other number bases:</B>
    <TABLE border=1>
    <<TR>
    <<TH>Decimal</TH>
    <<TH>Hexadecimal</TH>
    <<TH>Binary</TH>
    <</TR>
    <<SCRIPT language="JavaScript">
    <<!--
    var content = "";
    var i = 0;
    for (i = 0; i <= 255; i++){
        content = "<TR>";
        content = content + "<TD>" + i.toString(10) + "</TD>";
        content = content + "<TD>" + i.toString(16) + "</TD>";
        content = content + "<TD>" + i.toString(2) + "</TD></TR>";
    document.write(content)
    }

    //-->
    <</SCRIPT>
    <<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
    <</TABLE>
    <</BODY>
    <</HTML>

      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
