How to detect when mathjax is fully loaded?

Question

Is there anyway to identify when the mathjax is fully loaded to process mathematics. I need to hide my mathematics equations before mathjax is fully loaded and show \'loadin

Answer 1

For those who might be looking for the answer, this is the response i got from Mathjax developer

The way to synchronize with MathJax's startup actions it to register a StartupHook that will fire when the startup is complete. For example, you can use

MathJax.Hub.Register.StartupHook("End",function () { ... your startup code here ... });

at the end of the tag that configures MathJax, or in a separate tag just after loading MathJax if you are using the default MathJax configuration file in MathJax/config/MathJax.js. That should let you hook into MathJax's initialization sequence so you can do your own setup at the right time.

If you have Jquery loaded you can use getScript()

var mjaxURL  = 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS-MML_HTMLorMML,Safe.js';
// load mathjax script
$.getScript(mjaxURL, function() {
    // mathjax successfully loaded, let it render
    MathJax.Hub.Queue(["Typeset", MathJax.Hub, 'c'+parentid+'_list']);
});
