Add a popup calculator to a TWiki skin


Addressing a community of Engineers on an intranet, it is valuable to offer a popup calculator. This particular one is nice-looking and works in any modern browser (IE, Firefox) and operating system (Windows, Linux).

1. Add a calc link in any TWiki page using this code:

%INCLUDE{ "%SYSTEMWEB%.PopUpCalculatorAddOn" section="javascript" }%
%INCLUDE{ "%SYSTEMWEB%.PopUpCalculatorAddOn" section="link" }%

This will produce a link like this:






  • The "javascript" section should be included only once; omit this include in case the calendar has been added to the skin.
  • The "link" section can be included as many times as needed. In case of the "link" section include you can build your own link text or link button, make sure the link target (e.g. anchor href parameter) points to: javascript:openPopupWin('%PUBURL%/%SYSTEMWEB%/PopUpCalculatorAddOn/popup.html')

2. Add a calc link to the skin's header so that it is available on all TWiki pages:

Follow the add-on instructions below, or add a calc link in your WebTopBar as described in TWiki:Support.ReplaceJumpWithSearch.

Add-On Installation Instructions

Note: You do not need to install anything on the browser to use this add-on. The following instructions are for the administrator who installs the add-on on the server where TWiki is running.

  • Download the ZIP file from the Add-on Home (see below)
  • Unzip PopUpCalculatorAddOn.zip in your twiki directory
  • Edit your templates/twiki.pattern.tmpl, look where it defines SCRIPT, and add:
<script type="text/javascript">
<!-- <pre> HIDE
var popupWin;
function openPopupWin(addr)
  var chasm = screen.availWidth;
  var mount = screen.availHeight;
  var w = 240;
  var h = 410;
  popupWin=window.open(addr,'popupWin','status=no, width=' + w + ',height=' + h + ',left='
                           + ((chasm - w - 10) * .5) + ',top=' + ((mount - h - 30) * .5));
// </pre> HIDE -->
  • Edit your TWiki.WebTopBar and somewhere add the following code:
<a href="javascript:openPopupWin('%PUBURL%/%SYSTEMWEB%/PopUpCalculatorAddOn/popup.html')">calc</a>
  • Et voila, you now have a popup calculator on all your pages. Enjoy.
