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

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-error
document.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 = url
const 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"

v-if="this.type == 'url'"

</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 = this
if (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"

style="display: none"
ref="upload"
v-if="this.type == 'url'"

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