                Value: "8569"
            });

回答1:

You just have to change this code

 var text="";
jQuery.each( showStack, function( i, val ) {
  if(val.Key=='topic'){
    text+='\\text{'+ val.Value+'}'; // remove `
  }
  else
    text+=val.Value;
});

And add this code

var value='`'+text+'`';

 document.querySelector('#formula').textContent =value;
 MathJax.Hub.Queue(["Typeset",MathJax.Hub,'formula']);
