MathQuill.js

MathQuill.js通过html、css、javascript实现数学公式

<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>
