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 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 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/output/HTML-CSS");
This is the main routine called by MathJax when an element jax is to be converted to output. 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.
You should use MathJax.Hub.getJaxFor(script) to obtain the element jax for the given script. The translation process may 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 <script> tag.
| Parameters : |
|
|---|---|
| Returns : | the element jax resulting from the translation |
This registers the MIME-type for the element jax associated with this output jax so that MathJax knows to call this jax when it wants to display an element jax of that type. Several output jax may register for the same input jax, in which case the first one to register will be the default one for that type.
| Parameters : |
|
|---|---|
| Returns : | null |
Removes the output associated with the given element jax. The routine can use jax.SourceElement() to locate the <script> tag associated with the element jax.
| Parameters : |
|
|---|---|
| Returns : | null |
