LFAQ less frequently asked questions

The MathJax FAQ answers many basic questions about MathJax.

The MathJax User Group is the right place to ask further questions.

On this page we collect some of useful threads from the Mathjax User Group.

Can I use MathJax with my Javascript program?

Yes, but MathJax performs much of its activity asynchronously so be sure to synchronize your code with MathJax. See also these examples

Can I access the MathML code generate by a formula programmatically through javascript?

Yes, see this thread for an example, but again keep in mind that MathJax performs much its activity asynchronoulsy.

I modified/created a formula using Javascript but it is not displayed correctly by MathJax. Why?

MathJax processes the formulas when the page is loaded but you must ask MathJax to reprocess the formulas that are modified/created later. See Modifying Math on the Page See also these examples

How can I configure a local fallback for the CDN?

You might want to read this thread

<script src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"></script>
<script>window.MathJax || document.write('<script type="text/x-mathjax-config">MathJax.Hub.Config({"HTML-CSS":{imageFont:null }});<\/script>
<script src="<<PATH_TO_YOUR_LOCAL_MATHJAX>>MathJax.js?config=TeX-AMS_HTML-full"><\/ script>')</script>

Are there any fundamental differences between MathJax TeX input and TeX/LaTeX?

There aren't many, but here's one discussion .

Examples:

  • \sqrt\frac{3}{4} doesn't work. Enclosing the argument in curly braces works \sqrt{\frac{3}{4}}
  • \hat \mathbf u works in article, not in amsart (or MathJax) -- \hat{\mathbf u} works in amsart and MathJax.

How do I show MathJax menu on double-click?

Here's a thread discussing it and here's code that might help you get started.

How do I re-size text when the browser falls back to image fonts?

See this thread but note that there are very few reasons why your browser might fall back to image fonts for rendering -- be sure to check the FAQ
