Attention
Version 3 is now the current version of MathJax. This document is for version 1.
The mml2jax Preprocessor¶
The options below control the operation of the mml2jax preprocessor
that is run when you include "mml2jax.js"
in the extensions array
of your configuration. They are listed with their default values. To
set any of these options, include a mml2jax
section in your
MathJax.Hub.Config()
call. For example
MathJax.Hub.Config({
mml2jax: {
preview: "none"
}
});
would set the preview
parameter to "none"
.
- preview: "alttext"
This controls whether mml2jax inserts
MathJax_Preview
spans to make a preview available, and what preview to use, when it locates mathematics on the page. The default is"alttext"
, which means use the<math>
tag’salttext
attribute as the preview (visible until it is processed by MathJax), if the tag has one. Set it to"none"
to prevent the previews from being inserted (the math will simply disappear until it is typeset). Set it to an array containing the description of an HTML snippet in order to use the same preview for all equations on the page.Examples:
preview: ["[math]"], // insert the text "[math]" as the preview
preview: [["img",{src: "/images/mypic.jpg"}]], // insert an image as the preview
See the description of HTML snippets for details on how to represent HTML code in this way.
