我们知道若依框架用的Quill插件作富文本编辑器,上传视频的是插入视频链接,以iframe的形式插入。

能否实现,插入视频跟上传图片一样方便呢。

直接上代码(由于若依里面以及改造了上传图片功能,在此就不赘述了,主要讲插入视频)

这里直接贴完整的 Editor/index.vue

<template>
  <div>

    <el-upload
      class="upload-demo"
      name="file"
      :headers="headers"
      :action="uploadUrl"
      :before-upload="handleBeforeVideoUpload"
      :show-file-list="false"
      :on-success="handleVideoUploadSuccess"
      style="display: none"
    >
    </el-upload>

    <div class="editor" ref="editor" :style="styles"></div>


  </div>
</template>

<script>
import Quill from "quill";
import "quill/dist/quill.core.css";
import "quill/dist/quill.snow.css";
import "quill/dist/quill.bubble.css";
import { getToken } from "@/utils/auth";

const BlockEmbed = Quill.import('blots/block/embed')
class VideoBlot extends BlockEmbed {
  static create (value) {
    let node = super.create()
    node.setAttribute('src', value.url)
    node.setAttribute('controls', value.controls)
    node.setAttribute('width', value.width)
    node.setAttribute('height', value.height)
    node.setAttribute('webkit-playsinline', true)
    node.setAttribute('playsinline', true)
    node.setAttribute('x5-playsinline', true)
    return node;
  }

  static value (node) {
    return {
      url: node.getAttribute('src'),
      controls: node.getAttribute('controls'),
      width: node.getAttribute('width'),
      height: node.getAttribute('height')
    };
  }
}

VideoBlot.blotName = 'simpleVideo'
VideoBlot.tagName = 'video'
Quill.register(VideoBlot)
