.. _api-output-jax: *************************** The MathJax.OutputJax Class *************************** Output jax are the components of MathJax that translate mathematics from the MathJax internal format (an `element jax`) to whatever output is required to represent the mathematics (e.g., MathML elements, or HTML-with-CSS that formats the mathematics on screen). An output jax is stored as a pair of files in a subdirectory of the the ``jax/output`` directory, with the subdirectory name being the name of the output jax. For example, the NativeMML output jax is stored in `jax/output/NativeMML`. 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.OutputJax` object for the new output jax and registers it with MathJax, along with the MIME-type of the element jax that it can process. The main body of the output jax is stored in the second file, ``jax.js``, which is loaded when the output jax is first called on to translate some mathematics. This file augments the original output jax subclass with the additional methods needed to produce the output. MathJax calls the input jax's :meth:`Translate()` method when it needs the output jax to translate an element jax to produce output. The `MathJax.OutputJax` class is a subclass of the :ref:`MathJax Jax ` class, and inherits the properties and methods of that class. Those listed below are the additional or overridden ones from that class. Properties ========== .. describe:: name The name of the jax. .. describe:: version The version number of the jax. .. describe:: directory The directory where the jax files are stored (e.g., ``"[MathJax]/jax/output/HTML-CSS"``); Methods ======= .. Method:: Translate(script) :noindex: This is the main routine called by MathJax when an element jax is to be converted to output. The default :meth:`Translate()` method simply loads the ``jax.js`` file and returns that callback for that load function so that MathJax will know when to try the :meth:`Translate()` action again. When the ``jax.js`` file loads, it should override the default :meth:`Translate()` with its own version that does the actual translation; that way, when the second Translate call is made, it will be to the actual translation routine rather than the default loader. You should use ``MathJax.Hub.getJaxFor(script)`` to obtain the element jax for the given script. The translation process may add modify the element jax (e.g., if it has data that needs to be stored with the jax), and may insert DOM elements into the document near the jax's ``
