前言

需求：富文本编辑器

一、安装

npm install @wangeditor/editor --save
npm install @wangeditor/editor-for-vue --save

二、引用

1、 edit.vue

<template>
  <div>
    <Editor @onChange="onChange" :placeholder="placeholder" :editorHtml="editorHtml" :excludeKeys="['emotion','todo','fullScreen','uploadVideo','insertLink','insertTable','insertVideo']"/>
  </div>
</template>

<script>
import Editor from './Editor'
export default {
  components:{ Editor },
  data() {
    return {
      editorHtml:'',
      editorText:'',
      placeholder:`请输入~~~`,
    };
  },
  methods: {
    //编辑器修改内容
    onChange(html,text){
      this.editorHtml = html;
      this.editorText = text;
    },
  },
};
</script>

三、编辑器

1、Editor.vue

<template>
  <div class="w_editor">
    <div class="w_editor_box">
      <!-- 工具栏 -->
      <Toolbar class="w_editor_tool" :editor="editor" :defaultConfig="toolbarConfig" />
      <!-- 编辑器 -->
      <Editor class="w_editor_txt" :defaultConfig="editorConfig" v-model="html" @onChange="onChange" @onCreated="onCreated" @customPaste="customPaste" @onMaxLength="onMaxLength"/>
    </div>
  </div>
</template>

<script>
import { Editor, Toolbar } from '@wangeditor/editor-for-vue'
import { DomEditor } from '@wangeditor/editor'

let that;
const toolbarKeys = [
  //背景色,引用,粗体,无序列表,清除格式,行内代码,代码块,文字颜色,减少缩进,分割线,表情,字体,字号,全屏,标题
  'bgColor','blockquote','bold','bulletedList','clearStyle','code','codeBlock','color','delIndent','divider','emotion','fontFamily','fontSize','fullScreen','headerSelect',
  //增加缩进,网络图片,插入链接,插入表格,插入视频,居中对齐,两端对齐,左对齐,右对齐,行高,有序列表,重做,
  'indent','insertImage','insertLink','insertTable','insertVideo','italic','justifyCenter','justifyJustify','justifyLeft','justifyRight','lineHeight','numberedList','redo',
  //下标,上标,删除线,待办,下划线,撤销,上传图片,上传视频
  'sub','sup','through','todo','underline','undo','uploadImage','uploadVideo'
];

export default {
  name: 'editor',
  components: { Editor, Toolbar },
  props:{toolbarKeys:{type:Array,default:()=>{return []}},excludeKeys:{type:Array,default:()=>{return []}},placeholder:{type:String,default:''},editorHtml:{type:String,default:''}},
  data(e) {
    return {
      editor: null,
      html: '',
      toolbarConfig: {
        //显示菜单
        toolbarKeys: [],
        //隐藏菜单
        excludeKeys: [], //'fullScreen','uploadImage','uploadVideo','insertImage','insertLink','insertTable','insertVideo'
      },
      editorConfig: {
        // placeholder: '请输入内容...',
        // autoFocus: false,
        maxLength : 300,
        MENU_CONF: {
          'uploadImage':{
            // 自定义上传
            async customUpload(file, insertFn) {
              // that在这里使用 
              that.uploadFile(file);
              // 上传图片为例
              // 调用上传文件接口
              // 接口有uploadSuccess的，在回调执行插入
              // 没有回调的，上传成功后 用insertFn添加file的url,alt,href
              // insertFn(url,alt,href)
            }
          },
        }
      }
    }
  },
  methods: {
      //上传文件
      uploadFile(file){console.log(file,'上传文件')},
      //创建编辑器
      onCreated(editor) {
          this.editor = Object.seal(editor);
          this.initToolbar();
      },
      //初始化Toolbar

        this.$nextTick(()=>{
          let editor = this.editor;
          let editorConfig = editor.getConfig();
          let toolbar = DomEditor.getToolbar(editor);
          let toolbarConfig = toolbar.getConfig();
          //设置placeholder
          let placeholder = this.placeholder.length>0?this.placeholder:'请输入内容...';
          editorConfig.placeholder = placeholder;
          //设置显示菜单
          let insertKeys =  this.toolbarKeys.length>0?this.toolbarKeys:toolbarKeys;
          toolbarConfig.insertKeys={index:0,keys:insertKeys};
          //设置隐藏菜单
          if(this.excludeKeys.length>0){toolbarConfig.excludeKeys=this.excludeKeys;}
          //设置初始内容
          if(this.editorHtml.length>0){this.html = this.editorHtml;}
        });
      },
      // onChange 时获取编辑器最新内容
      onChange(editor) {this.$emit('onChange',editor.getHtml(),editor.getText());},
      //长度溢出限制
      onMaxLength(editor){},
      // 用户自定义粘贴
      customPaste(editor, event, callback){
        // event.preventDefault();
        let writedText = editor.getText()||'';
        let text = event.clipboardData.getData('text/plain')||'';
        //这里有个BUG   一次性粘贴内容超过this.editorConfig.maxLength的长度  也可以粘贴进去  目前没找到解决方法  需要在提交的时候验证一下editor.getText()长度
        if(text.length>this.editorConfig.maxLength||writedText.length+text.length>this.editorConfig.maxLength)return this.$message.warning(`文字超出${this.editorConfig.maxLength}字符`);
        return false;
      },
      //禁用
      disableHandler() {
        const editor = this.editor;
        if (!editor) return;
        editor.disable();

        if (!editor) return;
        const node = { type: 'image',src: data.previewUrl,alt: data.fileName,children: [ { text: '' } ]} //children: [ { text: '' } ]参数必须有，不然报错
        editor.insertNode(node);
        // editor.dangerouslyInsertHtml(``);// 强行插入html方法
      },
  },
  created(){ that = this; },
