javascript - 如何从 Mathquill Matheditor 输出为 LaTeX？

Question

当我尝试将 Mathquill 方程翻译成 LaTeX 语言时，我使用 Mathquill Matheditor 冻结了我的数学字段（无法在其中输入）。

<span id="math-field" class="mathquill-textbox" />
<textarea id="latex" name="content" />

这是我当前使用的 mathquill 脚本：https ://github.com/jipsen/matheditor/blob/master/mathquill.js

这是 Mathquill.com 头版的原始脚本，它什么都不做：

<p>Type math here: <span id="math-field"></span></p>
<p>LaTeX of what you typed: <span id="latex"></span></p>

<script>
var mathFieldSpan = document.getElementById('math-field');
var latexSpan = document.getElementById('latex');

var MQ = MathQuill.getInterface(2); // for backcompat
var mathField = MQ.MathField(mathFieldSpan, {
  spaceBehavesLikeTab: true, // configurable
  handlers: {
    edit: function() { // useful event handlers
      latexSpan.textContent = mathField.latex(); // simple API
    }
  }
});
</script>

我在下面提供 HTML 和脚本。

HTML：

<p>Type math here:
        <span id="math-field" maxlength="20"></span>
</p>
<p>LaTeX of what you typed:
        <span id="latex"></span>
</p>

JAVASCRIPT：

var mathField;
let mathFieldSpan = document.getElementById('math-field');
let latexSpan = document.getElementById('latex');
let MQ = MathQuill.getInterface(2); 

let config = {
    spaceBehavesLikeTab: true,
    restrictMismatchedBrackets: true,
    supSubsRequireOperand: true,
    handlers: {
        edit: function () { // useful event handlers
            var enteredMath = mathField.latex(); // Get entered math in LaTeX format
            latexSpan.textContent = enteredMath; // simple API
        }
    }
};
mathField = MQ.MathField(mathFieldSpan, config);
