Description
MediaWiki is an open source wiki engine licensed under the GNU General Public License. It is used by many websites, including this one.
The Jmol Mediawiki Extension enables the use of the JSmol object inside of Mediawiki pages.
Current version: 5.1, compatible with JSmol
(You can check which version a Wiki is using by going to the Special:Version
page in that Wiki)
Current status: (version 5, JSmol)
- The Jmol Mediawiki Extension is now using JSmol (in HTML5 modality by default, but also compatible with Java modality if you use a web browser that still supports Java applets). Some functionality was added, apart from compatibility with MediaWiki version 1.32.
Old status: (version 4, JSmol)
- The Jmol Mediawiki Extension used JSmol (in HTML5 modality by default, but also compatible with Java modality)
Older status: (version 3, Jmol-Java)
- Security is hopefully correct now. The delay effect can be obtained by using Jmol applet in a popup window.
- The Jmol Mediawiki Extension is fully functional and stabilized. It currently needs to be modified for a few things: better security, ability to delay loading the applet.
Wikis using the Jmol Extension
If you know a Wiki using the Jmol MediaWiki Extension, please add it to the list of Wikis using Jmol.
How to use the Jmol Extension
Once the Jmol Extension is installed in the Wiki, you can start adding JSmol objects and controls.
How to know if the Extension is installed, and which version it is? Visit the Special:Version
page in your wiki; the extension should be listed there.
- How to use version 5 of the Jmol Extension. Compatible with MediaWiki 1.32, PHP 7.0 and JSmol 14.29.32
- How to use version 4 of the Jmol Extension
- How to use version 3 of the Jmol Extension
Installation
(This must be done by the wiki administrator.)

Already solved
These are left here for reference, as you may still have these problems depending on your version of MediaWiki or your version of the Jmol MediaWiki Extension.
- The installation does not work when the wiki is installed in a non-root folder of the server (e.g. http://www.myserver.com/mywiki/index.php instead of http://mywiki.myserver.com/index.php).

- Partially fixed (2008-Dec-2) in revision 10411.
- Completely fixed (2008-Dec-8) in revision 10467.
- The scripts associated to checkboxes rendered by <jmolCheckbox> have no effect on the applet.
- Fixed (2008-Dec-8) in revision 10467.
- This was the discussion of the problem:
(Bob) something in /skins/common/wikibits.js?97 is disabling checkboxes.
(Nico) Yes, good catch, thanks a lot. Now, I need to find a way to overcome the behaviour of setupCheckboxShiftClick()
. I am going to ask on mediawiki list.
(Bugzilla) discussion
- Since Jmol scripting can include a call to javascript commands, the Jmol applet inserted by the Jmol MediaWiki Extension can execute arbitrary javascript added by any user editing the page (see demo). This is an unacceptable security hole for some systems such as Wikipedia, and will prevent Jmol from being used there. There is hence a need to implement a "scripting-without-javascript" mode of the applet, i.e. a way to completely disable the
javascript
command in Jmol scripts run from the MediaWiki Extension.
- Fixed (2008-Dec-8) in revision 10467.
- No javascript will be executed by Jmol applets inserted by the Extension.
- The signed applet was not being used even when explicitly authorized in the wiki configuration (
$wgJmolAuthorizeChoosingSignedApplet=true
) and requested for the applet (<signed>true</signed>
).
- Fixed (2008-Dec-8) in revision 10467.
- Now you can also have both signed and unsigned applets in the same page.
- Inserting applets with models read from php pages fails. The applet is using the <urlContents> tag and the url contains the '&' character.
- Fixed (2009-Nov-13) in revision 11738, version 3.2 of the Extension.
- The '&' is not tolerated by the wikicode. The solution is to use %26 (the wikicode for &) instead of the ampersand(s) in the url, content of the <urlContents> tag. The Extension will later filter those %26 codes and convert them to & so that the server correctly provides the model.
