最近项目中需要使用富文本编辑器,之前用的是vue-quill-editor,但是测试的时候发现这个编辑器会把内联的样式都清除掉,去查了一圈文档和各路网友的问答,有说这个就是quill的特性,不支持内联样式,具体原因我也没看明白,总之是改不动了,所以换了summernote。

summernote官网:https://summernote.org/
在网上找到了几篇相关的博客,结合个人使用经验做下总结笔记

实现效果:
这里写图片描述


目录
1. 需要安装的依赖包
2. 在webpack.base.conf.js中配置jquery
3. 在src/main.js中引入所需文件
4. 在页面中使用summernote
5. summernote取值和赋值
6. 上传图片
7. 自定义上传视频按钮

1 需要安装的依赖包:

"bootstrap": "^4.1.1",
"font-awesome": "^4.7.0",
"jquery": "^3.3.1",
"codemirror": "^5.37.0",
"summernote": "^0.8.10",

2 在webpack.base.conf.js中配置jquery

resolve: {
  extensions: ['.js', '.vue', '.json'],
  alias: {
    'vue$': 'vue/dist/vue.esm.js',
    '@': resolve('src'),
    'jquery': path.resolve(__dirname, '../node_modules/jquery/src/jquery')
  }
},

3 在src/main.js中引入所需文件(注意:引用路径可能不一样)

import 'bootstrap/dist/js/bootstrap.bundle.min'
import 'bootstrap/dist/css/bootstrap.css'
import 'font-awesome/css/font-awesome.css'
import 'summernote'
import 'summernote/dist/lang/summernote-zh-CN'
import 'summernote/dist/summernote.css'

4 在页面中使用summernote
(1)引入jquery

import $ from 'jquery'

(2)view

<div id="summernote" v-model="richContent"></div>

(3)在mounted中配置summernote

$('#summernote').summernote({
      lang: 'zh-CN',
      placeholder: '请输入内容',
      height: 600,
      width: 380,
      htmlMode: true,
      toolbar: [
        ['style', ['bold', 'italic', 'underline', 'clear']],
        ['fontsize', ['fontsize']],
        ['fontname', ['fontname']],
        ['color', ['color']],
        ['para', ['ul', 'ol', 'paragraph']],
        ['insert', ['link', 'picture']],
        ['mybutton', ['myVideo']]
      ],
      fontSizes: ['8', '9', '10', '11', '12', '14', '18', '24', '36'],
      fontNames: [
        'Arial', 'Arial Black', 'Comic Sans MS', 'Courier New',
        'Helvetica Neue', 'Helvetica', 'Impact', 'Lucida Grande',
        'Tahoma', 'Times New Roman', 'Verdana'
      ],
      buttons: {
        myVideo: myVideoBtn
      },
      callbacks: {
        onSubmit: function() {
          vm.richContent = $('#summernote').summernote('code')
        }
      }
    })

官网:https://summernote.org/deep-dive/
5 summernote取值和赋值

取值:$('#summernote').summernote('code')
赋值:$('#summernote').summernote('code', this.richContent)

6 上传图片(在(3)中的callbacks里添加下面这个函数)

onImageUpload: function(files) {
  upload(file,).then(url => { // 这个upload是自定义的上传文件函数,最后拿到图片的url,插入到富文本中
    $('#summernote').summernote('insertImage', url)
  })
}

7 自定义上传视频按钮

// mounted中加入下面这段
    window.uploadVideo = function() {
      vm.showLoading = true // 因ship上传比较耗时,所以加了个loading提示
      upload($('#video')[0].files[0]).then(url => {// upload是自定义的上传文件函数,这里是上传成功的回调,拿到视频的url
        var node = document.createElement('div') // 创建节点,用于包裹视频,再加这一层是方便调视频样式
        node.innerHTML = '<video controls="controls" style="max-width:100%;" src="' + url + '" />'
        node.cssText = 'width:100%;text-aligen:center;'
        $('#summernote').summernote('insertNode', node)// 插入视频
        vm.showLoading = false // 视频上传结束,去掉loading提示
      })
    }
    var myVideoBtn = function(context) {
      var ui = $.summernote.ui
      // create button
      var button = ui.button({
        contents: '<i class="rich-video-icon"/><input title="视频" onchange="uploadVideo()" type="file" id="videoInput" accept="video/*" style="opacity: 0; filter:Alpha(opacity=0);width:20px;height: 20px;margin-left: -20px;position:absolute;">', // 这个是展示在富文本顶部的操作图标,这个rich-video-icon是自己写的
        // tooltip: ''// todo 这个视频提示报错,未知原因
        // click: function() {// 点击按钮触发事件,这边不需要用到
          // context.invoke('editor.insertText', 'xxx')
        // }
      })
      return button.render() // return button as jquery object
    }

在(3)中的配置项中添加

buttons: {
   myVideo: myVideoBtn
}
