前言

在本文中笔者使用的是wangEditor,wangEditor是比较轻量级 web 富文本编辑器,配置方便,使用简单。 话不多说先看示例图

vue使用WangEdit富文本

一、vue引入富文本

npm install --save wangeditor

版本:3.1.1

二、使用步骤

1.自定义组件
代码如下(示例):

<template>
  <div>
    <div id="editor" ref="myEditor"></div>
    <slot></slot>
  </div>
</template>
<script>
  import WangEditor from 'wangeditor'
  export default {
    name: 'ComponentWangeditor',
    data () {
      return {
        edit: ''
      }
    },
    props: {
      value: {
        type: String,
        default: ''
      },
      config: {
        type: Array,
        default: () => {
          return {}
        }
      },
      uploadConfig: {
        type: Array,
        default: () => {
          return {
            method: 'http', // 支持custom(objurl)和http(服务器)和base64
            url: '/'
          }
        }
      }
    },
    computed: {
      customConfig () {
        return {
          pasteFilterStyle: false, // 关闭掉粘贴样式的过滤
          pasteIgnoreImg: false, // 粘贴时不忽略图片
          showLinkImg: false,
          menus:[          // 菜单配置
            'head',  // 标题
            'bold',  // 粗体
            'fontSize',  // 字号
            'fontName',  // 字体
            'italic',  // 斜体
            'underline',  // 下划线
            'strikeThrough',  // 删除线
            //'foreColor',  // 文字颜色
            //'backColor',  // 背景颜色
            //'link',  // 插入链接
            'list',  // 列表
            'justify',  // 对齐方式
            //'quote',  // 引用
            'emoticon',  // 表情
            'image',  // 插入图片
            // 'table',  // 表格
            // 'code',  // 插入代码
            'undo',  // 撤销
            'redo'  // 重复
          ],
          ...this.config
        }
      }
    },
    watch: {
      value: {
        deep: true,
        handler(val){
          this.editor.txt.html(val)// 生成编辑器
        }
      }

    },
    components: {},
    methods: {
      readBlobAsDataURL (blob, callback) {
        var a = new FileReader()
        a.onload = function (e) { callback(e.target.result) }
        a.readAsDataURL(blob)
      },
      initEditor () {
        var self = this
        this.editor = new WangEditor(this.$refs.myEditor)
        // 配置 onchange 事件
        this.editor.customConfig = this.customConfig
        // 将图片大小限制为 1M  2M的话就写2*1024*1024
        this.editor.customConfig.uploadImgMaxSize = 1 * 1024 * 1024
        //限制一次最多上传 1 张图片
        this.editor.customConfig.uploadImgMaxLength = 1
        this.editor.change = function () { // 编辑区域内容变化时
          self.$emit('input', this.txt.html())
          self.$emit('onchange', this.txt.html(), this.txt)
          // editor.txt.html('.....') //设置编辑器内容
          // editor.txt.clear() //清空编辑器内容
          // editor.txt.append('<p>追加的内容</p>')//继续追加内容。
          // editor.txt.text()  // 读取 text
          // editor.txt.getJSON()  // 获取 JSON 格式的内容
        }
        this.editor.customConfig.customUploadImg = function (files, insert) {
          if (self.uploadConfig.method === 'custom') {
            if (self.uploadConfig.callback) {
              self.uploadConfig.callback(files, insert)
            }
          }
          if (self.uploadConfig.method === 'base64') {
            files.forEach(file => {
              self.readBlobAsDataURL(file, function (dataurl) {
                insert(dataurl)
              })
            })
          }
          if (self.uploadConfig.method === 'http') {
            if (self.uploadConfig.callback) {
              self.uploadConfig.callback(files, insert)
            } else {
              var formData = new FormData()
              files.forEach(file => {
                formData.append('file', file)
              })
              self.$axios.post(self.uploadConfig.url, formData).then(({ data }) => {
                if (data.status === 'success') {
                  insert(data.url)
                }
              })
            }
          }
        }

        this.editor.create() // 生成编辑器
        this.editor.txt.text(this.value) // 生成编辑器
        this.$emit('oninit', this.editor)
      }
    },
    beforeCreate () {
    },
    created () {
    },
    beforeMount () {
    },
    mounted () {
      this.initEditor()
    }
  }
</script>

<style >
  .w-e-toolbar{
    flex-wrap:wrap;
  }

</style>

2.注册以及使用组件

代码如下(示例):

<template>
    <div>
        <antd-editor :uploadConfig="editorUploadConfig" v-model="editorContent" @onchange="changeEditor" @oninit="getEditor" />
    </div>
</template>

引入组件

import { AntdEditor } from '@/components'
<script>
  import { sysConsultiveEdit } from '@/api/modular/edu/consultiveManage'
  import { AntdEditor } from '@/components'
  import { imgUpload } from '@/api/modular/system/fileManage'
  export default {
    components: {
      AntdEditor
    },
    data() {
      return {
        editorContentText: '',
        editorUploadConfig: {
          method: 'custom',
          callback: this.editorUploadImage
        },
        editorContent: '',
        labelCol: {
          xs: {
            span: 24
          },
          sm: {
            span: 5
          }
        },
        wrapperCol: {
          xs: {
            span: 24
          },
          sm: {
            span: 15
          }
        },
        visible: false,
        confirmLoading: false,
        form: this.$form.createForm(this),
        loading: false,
        pic: ''
      }
    },
    methods: {

       */

        })
      },

        this.editor = editor
      },
      changeEditor (html, ele) {
        this.editorContent = html
        this.editorContentText = ele.text()
      },
      selfUpload(data) {
        const formData = new FormData()
        formData.append('file', data.file)

        if (!isLt2M) {
          this.$message.error('文件大小应小于 1M');
        }
        return isJPG && isLt2M
      },

        this.visible = true

        // 遍历所有Object
        for (OSSObjectSummary objectSummary : listing.getObjectSummaries()) {
            log.info(objectSummary.getKey());
        }
    }

}

4.AliyunConfig配置实体类

@Data
@Component
@ConfigurationProperties(prefix = "aliyun")
public class AliyunConfig {
    private String accessKeyId;
    private String accessKeySecret;
    private String endpoint;
    private String bucket;
    private String url;
}

5.application.yml配置文件

aliyun:
  accessKeyId:你的accessKeyId
  accessKeySecret: 你的accessKeySecret
  endpoint: https://oss-cn-shanghai.aliyuncs.com  //这个是示例
  bucket: 你的bucket
