MathJax:处理时隐藏数学表达式 [英] MathJax: hide math expression while processing

问题描述

我正在开发一种应用程序，该应用程序可以根据表单内容显示数学表达式.

Im developing an application that shows a mathematical expression in function of the content of a form.

网页在呈现表达式时会显示表达式的不同状态，我只想显示最后一个状态.

The webpage show the different states of the expression while its rendering, and I would like to show only the last state.

我已经隐藏了MathJax渲染时以Tex语言显示的数学表达式.

I have already hidden the mathematical expression while its shown in Tex language while MathJax is rendering.

但是还有两个状态:

• 处理:表达式使用更大的字体.
• Typesetted :最终版本，使用较小的字体.

• Processing: The expression is in a bigger font.
• Typesetted: The final version, in a smaller font.

我正试图通过以下方法隐藏其中之一:

Im trying to hide one of them through:

排版前停止 MathJax

或

在处理表达式时隐藏表达式

Hide the expression while processing it

有可能吗?

这是创建数学表达式的代码.

This is the code to create the mathematial expression.

JAVASCRIPT

JAVASCRIPT

window.UpdateMath = function () {

values = document.getElementsByClassName('level');
arrayvalues = toArray(values);

var formula = "$10 \log (";
for (i = 0; i < arrayvalues.length; i++) {
if (i == 0){
 formula = formula + " 10^{ &#92;frac{" + arrayvalues[i] + "}{10}} ";
}else{
 formula = formula + " + 10^{ &#92;frac{" + arrayvalues[i] + "}{10}} ";
}
}
formula = formula + ")$";

document.getElementById('MathOutput').style.visibility = "hidden";
document.getElementById("MathOutput").innerHTML = formula;

//reprocess the MathOutput Element
MathJax.Hub.Queue(["Typeset",MathJax.Hub,"MathOutput"]);
MathJax.Hub.Queue(
function () {
document.getElementById('MathOutput').style.visibility = "";
}
);
}
})();

推荐答案

您要关闭预处理器预览和快速预览.尝试将配置设置为此

You want to turn off preprocessor previews and the fast previews. Try setting your configuration to this

  MathJax.Hub.Config({
    "fast-preview": {disabled:true},
    tex2jax: {
      preview: "none",
      inlineMath: [["$","$"],["\\(","\\)"]]
    }
  });

这应该使事情更像您想要的工作.

This should make things work a bit more like what you want.
