若依RuoYi-Vue分离版—富文本Quill的图片支持伸缩大小及布局、工具栏带中文提示

    • 1.在vue.config.js 文件中添加 一下内容
    • 2.下载安装插件
    • 3.在Editor组件中引入插件
    • 4.使用Editor组件（特别注意要的加 v-if ）
    • 5.bug 之 imageResize的 img的style丢失
      • 1.先创建一个image.js的文件
      • 2.引入并注册 image.js 到Editor的vue文件中
    • 6.配置监听黏贴事件（看个人需求）

1.在vue.config.js 文件中添加 一下内容

const webpack = require('webpack');

在这里插入图片描述

new webpack.ProvidePlugin({'window.Quill': 'quill/dist/quill.js','Quill': 'quill/dist/quill.js'}),

在这里插入图片描述

2.下载安装插件

// 拖拽上传
npm install quill-image-drop-module --save
// 调整上传图片大小
npm i quill-image-resize-module --save 
// 粘贴图片上传
npm install quill-image-extend-module --save

3.在Editor组件中引入插件

修改ruoyi-ui\src\components\Editor下的 index.vue 文件

4.使用Editor组件（特别注意要的加 v-if ）

<template><div class="app-container"><!-- 此处一定要加上这个v-if判断，目的：保证那边只执行一次不然 editor 那边会触发两次(初始化rtfContent一次，rtfContent值改变一次),导致出现quil会出现一些问题。  --><div label="内容" v-if="form.rtfContent!=undefined"><editor v-model="form.rtfContent" :min-height="192"/></div></div>
</template><script>
import {addProfile, delProfile, getProfile, listProfile, updateProfile} from "@/api/yangdong/centerprofile";export default {name: "Profile",data() {return {rtfContent: undefined,},};},created() {this.getList();},mounted() {},methods: {/** 查询中心简介列表 */getList() {this.loading = true;listProfile(this.queryParams).then(response => {this.rtfContent= response.rows.rtfContent;});},}
};
</script><style scoped>
.testParent{/*width: 700px;*//*height: 200px;*/display: flex;flex-direction: row; /*默认也是row可以不写*//*background-color: #428BCA;*/align-items: center;  /*这种情况是垂直居中*/justify-content: center;/*这种情况是水平居中*/}/deep/ .el-table th.must>.cell:before {content: '*';color: #ff1818;
}/* 以下为详情遮住样式*/
::v-deep .avue-crud__dialog__header {display: -webkit-box;display: -ms-flexbox;display: flex;-webkit-box-align: center;-ms-flex-align: center;align-items: center;-webkit-box-pack: justify;-ms-flex-pack: justify;justify-content: space-between;
}
/* 以下为缩放按钮样式*/
::v-deep .avue-crud__dialog__menu {padding-right: 20px;float: left;
}
::v-deep .avue-crud__dialog__menu i {color: #909399;font-size: 15px;
}
::v-deep .el-icon-full-screen{cursor: pointer;
}
::v-deep .el-icon-full-screen:before {content: "\e719";
}
</style>

5.bug 之 imageResize的 img的style丢失

原因：

执行this.Quill.pasteHTML(this.currentValue) 的时候，
会把htm的代码渲染在富文本(Quill) ，但是却把在img上面的style被清除掉了,于是就出现了再次编辑时图片位置异常
内部存在某些规则，导致

解决方式：

直接也研究了半天，最后虽然实现了，但是过程很辅助，采取了，DOM 操作（加点击事件，重新渲染html、quil等等），过程极其难受
本人不是纯弄前端，心累的很。。。。。
后面发现了一篇博客，方式简单（使用了 自定义的Quill.js的Blot（块）），果断用了他的。在此非常感谢
博客地址如下：vue使用quill编辑器自定义图片上传方法、quill-image-resize-module修改图片、监测粘贴的是图片上传到后端、重新进入编辑器img标签丢失style属性

1.先创建一个image.js的文件

由于我这边是若依框架里面的。所以的位置为 ruoyi-ui\src\components\Editor,和index.vue 并级

import Quill from 'quill'
const EmbedBlot = Quill.import('formats/image')
// 添加style,解决重进编辑器ima标签丢掉style属性问题
const ATTRIBUTES = ['alt', 'height', 'width', 'style']class Image extends EmbedBlot {static blotName = 'image';static tagName = 'IMG';static create(value) {const node = super.create(value)if (typeof value === 'string') {// 保留原来的图片方法node.setAttribute('src', this.sanitize(value))} else {// 自定义图片方法node.setAttribute('src', value.src)// 使用了vue-photo-preview所以添加preview，preview-text这两个属性node.setAttribute('preview', '1') // preview相同的为一组node.setAttribute('preview-text', value.title) // 图片名称，预览时显示使用}return node}static formats(domNode) {return ATTRIBUTES.reduce((formats, attribute) => {if (domNode.hasAttribute(attribute)) {formats[attribute] = domNode.getAttribute(attribute)}return formats}, {})}static match(url) {return /\.(jpe?g|gif|png)$/.test(url) || /^data:image\/.+;base64/.test(url)}static register() {if (/Firefox/i.test(navigator.userAgent)) {setTimeout(() => {// Disable image resizing in Firefox// @ts-expect-errordocument.execCommand('enableObjectResizing', false, false)}, 1)}}static sanitize(url) {return sanitize(url, ['http', 'https', 'data']) ? url : '//:0'}static value(domNode) {return domNode.getAttribute('src')}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)}}
}
function sanitize(url, protocols) {const anchor = document.createElement('a')anchor.href = urlconst protocol = anchor.href.slice(0, anchor.href.indexOf(':'))return protocols.indexOf(protocol) > -1
}export default Image

2.引入并注册 image.js 到Editor的vue文件中

import Image from "./image";
Quill.register(Image, true);

完整的代码如下

<template><div><el-upload:action="uploadUrl":before-upload="handleBeforeUpload":on-success="handleUploadSuccess":on-error="handleUploadError"name="file":show-file-list="false":headers="headers"style="display: none"ref="upload"v-if="this.type == 'url'"></el-upload><div class="editor" ref="editor" :style="styles"></div></div>

6.配置监听黏贴事件（看个人需求）

参考：若依框架前后分离版本富文本增加图片上传及移动和放大缩小

（1）首先得安装jq

npm install jquery --save-dev

（2）引入jq

//引入jq
import $ from 'jquery';

（3）修改以下代码

  • 原来
<div class="editor" ref="editor" :style="styles"></div>
  • 改为
<div class="editor" ref="editor" :style="styles" @paste="handlePaste($event)"></div>

增加

handlePaste(evt) {let that = thisif (evt.clipboardData &&evt.clipboardData.files &&evt.clipboardData.files.length) {evt.preventDefault();[].forEach.call(evt.clipboardData.files, (file) => {if (!file.type.match(/^image\/(gif|jpe?g|a?png|bmp)/i)) {return;}const formData = new FormData();formData.append("file", file);//后台上传接口的参数名// 实现上传$.ajax({type: "post",url: process.env.VUE_APP_BASE_API +'/common/upload', // 上传的图片服务器地址data: formData,headers:{'Authorization': "Bearer " + getToken()},//必须dataType: "json",processData: false,contentType: false,//设置文件上传的type值，必须success: (response) => {if (response.code == 200 || response.code == 0) {//当编辑器中没有输入文本时，这里获取到的 range 为 null// 获取富文本组件实例let quill = that.Quill;var range = quill.selection.savedRange;//图片插入在富文本中的位置var index = 0;if (range == null) {index = 0;} else {index = range.index;}//将图片链接插入到当前的富文本当中quill.insertEmbed(index, "image", response.url);// 调整光标到最后quill.setSelection(index + 1); //光标后移一位}},error: function () {this.$message.error('上传失败！')},});});}},

完整的代码如下

<template><div><el-upload:action="uploadUrl":before-upload="handleBeforeUpload":on-success="handleUploadSuccess":on-error="handleUploadError"name="file":show-file-list="false":headers="headers"style="display: none"ref="upload"v-if="this.type == 'url'"></el-upload><div class="editor" ref="editor" :style="styles" @paste="handlePaste($event)"></div></div>
