Input jax are the components of MathJax that translate mathematics from its original format (like TeX or MathML) to the MathJax internal format (an element jax).
An input jax is stored as a pair of files in a subdirectory of the jax/input directory, with the subdirectory name being the name of the input jax. For example, the TeX input jax is stored in jax/input/TeX. The first file, config.js, is loaded when MathJax is being loaded and configured, and is indicated by listing the input jax directory in the jax array of the MathJax configuration. The config.js file creates a subclass of the MathJax.InputJax object for the new input jax and registers that with MathJax, along with the MIME-type that will be used to indicate the mathematics that is to be processed by the input jax.
The main body of the input jax is stored in the second file, jax.js, which is loaded when the input jax is first called on to translate some mathematics. This file augments the original input jax subclass with the additional methods needed to do the translation. MathJax calls the input jax’s Translate() method when it needs the input jax to translate the contents of a math <script> tag.
The MathJax.InputJax class is a subclass of the MathJax Jax class, and inherits the properties and methods of that class. Those listed below are the additional or overridden ones from that class.
The name of the jax.
The version number of the jax.
The directory where the jax files are stored (e.g., "[MathJax]/jax/input/TeX");
The name of the ElementJax class that this input jax will produce (typically mml, as that is the only ElementJax at the moment).
This is the main routine called by MathJax when a <script> of the appropriate type is found. The default Translate() method throws an error indicating that Translate() hasn’t been redefined, so when the jax.js file loads, it should override the default Translate() with its own version that does the actual translation.
The translation process should include the creation of an Element Jax that stores the data needed for this element.

---|---|
Returns : | the element jax resulting from the translation |
This registers the MIME-type associated with this input jax so that MathJax knows to call this input jax when it sees a <script> of that type. An input jax can register more than one type, but it will be responsible for distinguishing elements of the various types from one another.
