how do i know the translate process finished

[lindaz...@gmail.com]

hi, i am from china, now i meet a problem, i need call a function after the  translate process finished(i mean the equation was translated finished), then i find answer on google, it provide two methods, one is 

MathJax.Hub.Register.StartupHook("MathMenu Ready",function () {

               console.log(1);

           });

and other is 

MathJax.Hub.Queue(function (End) {

    console.log(1);

 });

but it not useful.......

so, can you help me? my english is poor, thank you reading my email.

Hi,

The first piece of code will run `console.log(1)` after the MathJax Menu extension has loaded.

The second piece of code will run `console.log(1)` once the MathJax queue is empty -- that's what you probably want. For a live example see https://codepen.io/pkra/pen/LWowOq?editors=1111..

Regards,

Peter

thank you, i guess that  i express imcorrectly , when i use mathjax.js, i translate the data that server end passed to me first, like this (they are processed by me)

then mathjax dynamicly translate, but now users can see the translation, i don't hope they see it, so i add a loading spinner, when the formula translated finished, the loading spinner will disapper , so which event can do this??

You can build this kind of logic using the queue. I've updated the example with some simple hide/unhide code.

my web page have much formulas in one page, the translation is from top to bottom, when the user open the page, he see that the formula that half is good and half is bad, i hope they see the page after all formulas translated . this is my problem.
