一般的使用参考文档的是使用方法，参考如下

<template>
  <div class="example">
    <quill-editor
      class="editor"
      ref="myTextEditor"
      :value="content"
      :options="editorOption"
      @change="onEditorChange"
      @blur="onEditorBlur($event)"
      @focus="onEditorFocus($event)"
      @ready="onEditorReady($event)"
    />
    <div class="output code">
      <code class="hljs" v-html="contentCode"></code>
    </div>
    <div class="output ql-snow">
      <div class="ql-editor" v-html="content"></div>
    </div>
  </div>
</template>

实现一个粘贴图片的功能

刚开始接触 vue 的开发，就接了个需求是实现富文本粘贴功能。 直接上代码。

// 输出一个模块
export class ImagePaste {
  //quill 和 options->方便定义一些配置
  constructor(quill, options = {}) {
    // save the quill
    this.quill = quill;
    //绑定事件
    this.handlePaste = this.handlePaste.bind(this);
    // 坚挺粘贴事件
    this.quill.root.addEventListener("paste", this.handlePaste, false);
  }

  //处理粘贴事件
  //还需要根据复制的数据类型作一下判断
  //  读取到剪贴板中的数据 具体的参考使用 可以看下MDN的文档 基本主流的浏览器都支持了
  handlePaste(e) {
    if (
      e.clipboardData &&
      e.clipboardData.items &&
      e.clipboardData.items.length
    ) {
      const clipboardData = e.clipboardData;
      const items = clipboardData.items;
      const item = items[0];
      if (item && item.kind === "file" && item.type.match(/^image\//i)) {
        e.preventDefault()
        this.file = item.getAsFile();
        this.toBase64();
      }
    }
  }

  toBase64() {
    // 转换成base64 也可以压缩图片进行上传
    const reader = new FileReader();
    reader.onload = e => {
      this.insertImg(e.target.result);
    };
    reader.readAsDataURL(this.file);
  }

  insertImg(baseUrl) {
    // 插入文本中
    const currentIndex = this.quill.getSelection().index || 0;
    this.quill.insertEmbed(currentIndex, "image", baseUrl);
    this.quill.setSelection(currentIndex + 1);
    this.quill.update();
    // 更新光标的位置
  }
}

使用

import { quillEditor, Quill } from "vue-quill-editor";
import ImagePaste;

Quill.register("modules/ImagePaste", ImagePaste);

import "quill/dist/quill.core.css";
import "quill/dist/quill.snow.css";
import "quill/dist/quill.bubble.css";
