Epiceditor paired with MathJax

Question

Is there anyway to load a script (such as MathJax) into the EpicEditor preview iFrame? I want my previews to be correct Markdown and then have the javascript run to preview the MathJax content.

Thanks!

It seems that you ought to inject MathJax script manually into previewer iframe. Something like this:

var editor = new EpicEditor(opts).load();

previewer = editor.getElement('previewer');
var mathjax = previewer.createElement('script');
mathjax.type = 'text/javascript';
mathjax.src = 'http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML';
previewer.body.appendChild(mathjax);

var config = previewer.createElement('script');
config.type = 'text/x-mathjax-config';
config.text = "MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$']], displayMath: [['$$','$$']], processEscapes: true}});";
previewer.body.appendChild(config);

And then you can render equations on preview event:

editor.on('preview', function() {
    editor.getElement('previewerIframe').contentWindow.eval(
        'MathJax.Hub.Queue(["Typeset",MathJax.Hub]);');
});

That also works in fullscreen live edit mode.
