quill富文本编辑器自定义字体、文字大小（编辑器内含element上传组件）

如下是我们需要得到的文字大小和字体的效果:

自定义字体、文字大小JS部分：

//引入Qill插件
import Quill from "quill";

// 自定义字体
let fontFamily = ['SimSun', 'SimHei', 'Microsoft-YaHei', 'KaiTi', 'FangSong', 'Arial', 'pingfang'];
Quill.imports['formats/font'].whitelist = fontFamily;
Quill.register(Quill.imports['formats/font'])

// 自定义文字大小
let fontSize = ['10px', '12px', '14px', '16px', '20px', '24px', '36px']
Quill.imports['attributors/style/size'].whitelist = fontSize;
Quill.register(Quill.imports['attributors/style/size']);

const toolbarOptions = [
  [
    "bold",
    "italic",
    "underline",
    "strike",
    "blockquote",
    "code-block",
    { header: 1 },
    { header: 2 },
    { list: "ordered" },
    { list: "bullet" },
    { indent: "-1" },
    { indent: "+1" },
    { script: "sub" }, // 下标
    { script: "super" }, // 上标
    { align: [] },
    { color: [] },
    { background: [] },
    "link",
    "image",
  ],
  [{ size: fontSize }], // 文字大小
  [{ header: [1, 2, 3, 4, 5, 6, false] }], // 标题
  [{ font: fontFamily }], // 字体
];

自定义字体、文字大小css部分：
