vue 中quill富文本视频标签为video且自定义宽高

原始视频添加 改版后 成功添加视频

1.我们要先修改quill源码中视频<iframe> 标签为<video>和宽高设置，新建js为quill-video.js

import Quill from "quill";

// 源码中是import直接倒入，这里要用Quill.import引入
const BlockEmbed = Quill.import('blots/block/embed')
const Link = Quill.import('formats/link')

const ATTRIBUTES = ['height', 'width']

class Video extends BlockEmbed {
  static create(value) {
    let node = super.create()
    //添加
    node.setAttribute('src', value.url)
    node.setAttribute('controls', value.controls)
    node.setAttribute('width', value.width)
    node.setAttribute('height', value.height)
    return node
  }

  static formats (domNode) {
    return ATTRIBUTES.reduce((formats, attribute) => {
      if (domNode.hasAttribute(attribute)) {
        formats[attribute] = domNode.getAttribute(attribute)
      }
      return formats
    }, {})
  }

  static sanitize (url) {
    return Link.sanitize(url)
  }

  static value (domNode) {
    // 设置值包含宽高，为了达到自定义效果
    //宽高为空的话，就是按100%算
    return {
      url: domNode.getAttribute('src'),
      controls: domNode.getAttribute('controls'),
      width: domNode.getAttribute('width'),
      height: domNode.getAttribute('height')
    }
  }


  format (name, value) {
    if (ATTRIBUTES.indexOf(name) > -1) {
      if (value) {
        this.domNode.setAttribute(name, value)
      } else {
        this.domNode.removeAttribute(name)
      }
    } else {
      super.format(name, value)
    }
  }

  html () {
    const { video } = this.value()
    return `<a href="${video}">${video}</a>`
  }
}
Video.blotName = 'video'
// Video.className = 'ql-video' // 可添加样式，看主要需要
Video.tagName = 'video' // 用video标签替换iframe

export default Video

2.封装quill组件

<template>
  <div>
    <!-- 图片上传 -->
    <el-upload
      :action="uploadUrl"
      :on-success="handleUploadSuccess"
      :on-error="handleUploadError"
      name="file"
      :show-file-list="false"
      :headers="headers"
      style="display: none"
      ref="upload"
      v-if="this.uploadUrl"
    >
    </el-upload>
    <!-- 视频弹窗 -->
    <el-dialog
      width="650px"
      id="videoUpload"
      title="视频上传"
      :visible.sync="videoUploadTag"
      append-to-body
      :close-on-click-modal="false"
    >
      <el-form ref="videoObj" :model="videoObj" label-width="80px">
        <el-form-item label="视频链接">
          <el-input
            v-model="videoObj.videoLink"
            placeholder="请输入视频链接"
            clearable
          ></el-input>
        </el-form-item>
        <el-row>
          <el-col :span="10">
            <el-form-item label="宽">
              <el-input-number
                :min="200"
                controls-position="right"
                v-model="videoObj.videoWidth"
                placeholder="请输入自定义宽"
                clearable
              ></el-input-number>
            </el-form-item>
          </el-col>
          <el-col :span="10" :offset="3">
            <el-form-item label="高">
              <el-input-number

                controls-position="right"
                v-model="videoObj.videoHeight"
                placeholder="请输入自定义高"
                clearable
              ></el-input-number> </el-form-item
          ></el-col>
        </el-row>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button type="primary" @click="addVideoLink()">添加</el-button>
      </div>
    </el-dialog>

<script>
import Editor from "@/components/Editor";

export default {
  components: {

  },
  data() {
    return {
      content: ""
    };
