Simple plugin for OctoberCMS. The plugin enables MathJax in the backend blog entry page, so that blog post previews containing mathematical formulas are rendered correctly.
MathJax is a de facto standard for allowing high-quality typeset matematical formulas on the web, using LaTeX markup.
This plugin allows you to have live rendering of MathJax in the blog preview area when you are writing blog posts with mathematical content.
You still need to configurate MathJax in the frontend layout for your theme to get rendering of mathematical formulas in the frontend. Typically, you want to add something like
<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
in your layout file, possibly together with some extra configuration. See the MathJax web site for more details.
The plugin works by injecting MathJax Javascript into the Rainlab\Blog\Controllers\Posts
controller, making sure MathJax is loaded on the relevant backend pages.
To provide live rendering in the blog preview pane, a jQuery function provides
a textarea.keyup event handler. To prevent unneccesary flickering, the event
handler fires once the user hasn't entered any input for 2 seconds.
When the event handler fires, MathJax is asked to typeset the text in the preview pane.
