SimpleMathJax 拡張機能は JavaScript ライブラリMathJaxを使用して MediaWiki の内でmathタグ形式をTeX数式で表現してくれます。 This extension will load resources from cdn.jsdelivr.net on all wiki pages that have math or chem tags.

  • Simple
  • Lightweight
  • UTF-8 Support
  • Mobile View OK
  • Setting Font Size
  • chem tag support for chemistry
  • additional inlineMath symbols pairs support
  • MediaWiki Style! Look at the samples.


Or you can git clone.

$ git clone https://github.com/jmnote/SimpleMathJax.git

If you want to use local MathJax scripts (and not a CDN), then you can use git clone recursive. In most cases, CDN is much faster than your server. However, a CDN may not be available if you have a hardened PHP installation due to disabled_functions restrictions.

$ git clone --recursive https://github.com/jmnote/SimpleMathJax.git

SimpleMathJax is meant to be used as an alternative to the Math extension. If the Math extension is installed it may take precedence and cause SimpleMathJax to not work. The SimpleMathJax extension is the only thing you need to start rendering equations.


The following variables can be defined in LocalSettings.php after calling wfLoadExtension( 'SimpleMathJax' );. Note that for a simple site adding $wgSmjScale = 1.1; might be all you need to make it Just Work™.

バージョン 設定名 既定値 説明
0.7.0+ $wgSmjUseCdn true Using CDN or Local resource
0.7.0+ $wgSmjUseChem true enable ‎<chem> tags
( defaults to use chem tags )
0.8.0+ $wgSmjEnableMenu true Make MathJax context menu available
This setting is missed since 0.8.0; it would be a mistake
0.8.0+ $wgSmjExtraInlineMath [] can add some additional inlineMath symbols pairs
0.8.1+ $wgSmjScale 1 The default font size for SimpleMathJax
0.7.4 $wgSmjShowMathMenu false (除去済)
($wgSmjEnableMenu に置き換えられました)
0.6.1 $wgSmjSize 110 (除去済)
($wgSmjScale に置き換えられました)
0.6.1 $wgSmjInlineMath [] (除去済)
($wgSmjExtraInlineMath に置き換えられました)
0.6.1 $wgSmjDisableChem false (除去済)
($wgSmjUseChem に置き換えられました)
0.6.1 $wgSmjScripts ['//cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-AMS-MML_HTMLorMML',
($wgSmjUseCDN に置き換えられました)
can use local or another remote scripts
( defaults to use cloudflare CDN )
0.6 $wgSimpleMathJaxSize 125 (除去済)
($wgSmjSize に置き換えられました)
0.6 $wgSimpleMathJaxUseCDN true (除去済)
($wgSmjScripts に置き換えられました)
0.6 $wgSimpleMathInlineMath [] (除去済)
($wgSmjInlineMath に置き換えられました)

If you want to change font size, set $wgSmjScale like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjScale = 1.5;

If you want to enable some additional inlineMath symbol pairs, set $wgSmjExtraInlineMath like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjExtraInlineMath = [ [ "$", "$" ], [ "\\(", "\\)" ] ];

If you want to use local module, set $wgSmjUseCdn like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjUseCdn = false;

SimpleMathJax and Live Preview (versions < 0.8.0)

Prior to version 0.8.0, the following had to be added to MediaWiki:Common.js in order to have the Live Preview in the editor show rendered math output instead of raw LaTeX source code:

function waitForMathJax($content) {
  if (typeof MathJax === 'undefined') {
    setTimeout(function () { waitForMathJax($content); }, 1000);
  } else {
    MathJax.Hub.Queue(["Typeset", MathJax.Hub, $content[0]]).execute();






  1. SimpleMathJax 0.8.0+ uses manifest_version 2. Manual:extension.json/スキーマ
