      When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and
      they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

在vue中数据变化后需要重新渲染一下才能更改公式：

      clearTimeout(timer);
      timer = setTimeout(() => {
        this.$nextTick(() => {
          window.MathJax.typeset();
        });
      }, 500);

自制mathjax在线编辑器。

<template>
  <div>
    <div>mathValue：</div>
    <p v-html="mathValue"></p>
    <el-input
      :value="mathValue"
      type="textarea"
      @input="handleMathValue"
    ></el-input>
  </div>
</template>

<script>
import { MathfieldElement } from "mathlive";
let mf;
export default {
  data() {
    return {
      mathValue: "\\( x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a} \\)",
    };
  },
  mounted() {
    this.formatMath();
  },

  methods: {
    formatMath() {
      window.MathJax.typeset();
    },
    handleMathValue(e) {
      this.mathValue = e;
      this.$nextTick(() => {
        this.formatMath();
      });
    },
  },
};
</script>
