使用vue的富文本编辑器操作
vue的富文本编辑器使用以及多图片文件上传与回显

一. vue-quill-edit

1. 安装vue的富文本

cd 当前的vue项目路径
npm install quill --save
npm install vue-quill-editor --save

2. 在页面中引入vue的富文本

//引入Vue的ueditor的资源
import {quillEditor} from "vue-quill-editor"; //调用编辑器
import 'quill/dist/quill.core.css';
import 'quill/dist/quill.snow.css';
import 'quill/dist/quill.bubble.css';
import quillConfig from '../../common/js/quill-config';

3. 添加组件

export default {components: {quillEditor},//......

4. 使用组件

<el-form-item label="简介" prop="intro"><!-- v-if="editForm.petDetail" 修改v-model绑定对象报错问题，v-if对需要显示的数据判断下 --><quill-editor v-model="editForm.petDetail.intro" v-if="editForm.petDetail":options="quillOption"></quill-editor>
</el-form-item>
<el-form-item label="领养须知" prop="orderNotice"><quill-editor v-model="editForm.petDetail.adoptNotice" v-if="editForm.petDetail":options="quillOption"></quill-editor>
</el-form-item>

5. 整个表单

<!--编辑界面-->
<el-dialog :title="title" :visible.sync="editFormVisible" :close-on-click-modal="false" width="60%" @close="cancel"><el-form :model="editForm" label-width="80px" :rules="editFormRules" ref="editForm"><el-form-item label="宠物名称" prop="name"><el-input prefix-icon="el-icon-tickets" v-model="editForm.name" auto-complete="off"></el-input></el-form-item><el-form-item label="成本价" prop="costprice"><el-input-number :min="0" οninput="if(value<0)value=0" v-model.trim="editForm.costprice"auto-complete="off"></el-input-number></el-form-item><el-form-item label="销售价" prop="saleprice"><el-input-number :min="0" οninput="if(value<0)value=0" v-model.trim="editForm.saleprice"auto-complete="off"></el-input-number></el-form-item><el-form-item label="宠物类型" prop="type"><div class="block"><el-cascaderv-model="editForm.typeId":options="petTypeTree":props="{ checkStrictly: true,value:'id',label:'name' }"clearable></el-cascader></div></el-form-item><el-form-item label="宠物图片" prop="index"><el-upload class="upload-demo"action="http://localhost:8080/fastDfs/":on-preview="handlePreview":on-remove="handleRemove":on-success="handleSuccess":file-list="fileList"list-type="picture"><el-button size="small" type="primary">点击上传</el-button><div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div></el-upload></el-form-item><el-form-item label="状态"><el-radio-group v-model="editForm.state"><el-radio class="radio" :label="1">开启</el-radio><el-radio class="radio" :label="0">关闭</el-radio></el-radio-group></el-form-item><el-form-item label="上架时间" prop="onsaletime"><div class="block"><el-date-pickervalue-format="yyyy-MM-dd HH:mm:ss"v-model="editForm.onsaletime"type="datetime"placeholder="选择日期时间"align="right":picker-options="pickerOptions"></el-date-picker></div></el-form-item><el-form-item label="下架时间" prop="offsaletime"><div class="block"><el-date-pickervalue-format="yyyy-MM-dd HH:mm:ss"v-model="editForm.offsaletime"type="datetime"placeholder="选择日期时间"align="right":picker-options="pickerOptions"></el-date-picker></div></el-form-item><el-form-item label="所属店铺" prop="shop"><el-select v-model="editForm.shopId" placeholder="请选择店铺" clearable><el-optionv-for="item in shops":key="item.id":label="item.name":value="item.id"></el-option></el-select></el-form-item><el-form-item label="领养人"><el-select v-model="editForm.userId" placeholder="请选择领养人" clearable><el-optionv-for="item in users":key="item.id":label="item.username":value="item.id"><span style="float: left">{{ item.username }}</span><span style="float: right; color: #8492a6; font-size: 13px">{{ item.phone }}</span></el-option></el-select></el-form-item><el-form-item label="简介" prop="intro"><!-- v-if="saveForm.petDetail" 修改v-model绑定对象报错问题，v-if对需要显示的数据判断下 --><quill-editor v-model="editForm.petDetail.intro" v-if="editForm.petDetail":options="quillOption"></quill-editor></el-form-item><el-form-item label="领养须知" prop="orderNotice"><quill-editor v-model="editForm.petDetail.adoptNotice" v-if="editForm.petDetail":options="quillOption"></quill-editor></el-form-item></el-form><div slot="footer" class="dialog-footer"><el-button @click.native="cancel">取消</el-button><el-button type="primary" @click.native="editSubmit" :loading="editLoading">提交</el-button></div>
</el-dialog>

二. 富文本整合Fastdfs

图片上传到服务器保存

编辑富文本内容的时候，原生的富文本，会直接将图片以base64编码的方式存储在页面上。当点击保存时，会直接将base64的数据直接存储到数据库，数据库的字段直接存储不了，内容太大！所以需要将富文本编辑框集成FastDfs，将图片上传到FastDfs。只存储图片的FastDfs访问路径即可。

1. quill-config.js

/*富文本编辑图片上传配置*/
const uploadConfig = {fastDfsUrl:'http://123.207.27.208',      // 图片访问地址action:  'http://localhost:8080/fastDfs', // 必填参数 图片上传地址methods: 'POST',  // 必填参数 图片上传方式token: '',  // 可选参数 如果需要token验证，假设你的token有存放在sessionStoragename: 'file',  // 必填参数 文件的参数名size: 500,  // 可选参数   图片大小，单位为Kb, 1M = 1024Kbaccept: 'image/png, image/gif, image/jpeg, image/bmp, image/x-icon'  // 可选 可上传的图片格式
};// toolbar工具栏的工具选项（默认展示全部）
const toolOptions = [['bold', 'italic', 'underline', 'strike'],['blockquote', 'code-block'],[{'header': 1}, {'header': 2}],[{'list': 'ordered'}, {'list': 'bullet'}],[{'script': 'sub'}, {'script': 'super'}],[{'indent': '-1'}, {'indent': '+1'}],[{'direction': 'rtl'}],[{'size': ['small', false, 'large', 'huge']}],[{'header': [1, 2, 3, 4, 5, 6, false]}],[{'color': []}, {'background': []}],[{'font': []}],[{'align': []}],['clean'],['link', 'image', 'video']
];
const handlers = {image: function image() {var self = this;var fileInput = this.container.querySelector('input.ql-image[type=file]');if (fileInput === null) {fileInput = document.createElement('input');fileInput.setAttribute('type', 'file');// 设置图片参数名if (uploadConfig.name) {fileInput.setAttribute('name', uploadConfig.name);}// 可设置上传图片的格式fileInput.setAttribute('accept', uploadConfig.accept);fileInput.classList.add('ql-image');// 监听选择文件fileInput.addEventListener('change', function () {// 创建formDatavar formData = new FormData();formData.append(uploadConfig.name, fileInput.files[0]);formData.append('object','product');// 如果需要token且存在tokenif (uploadConfig.token) {formData.append('token', uploadConfig.token)}// 图片上传var xhr = new XMLHttpRequest();xhr.open(uploadConfig.methods, uploadConfig.action, true);// 上传数据成功，会触发xhr.onload = function (e) {if (xhr.status === 200) {var res = JSON.parse(xhr.responseText);let length = self.quill.getSelection(true).index;//这里很重要，你图片上传成功后，img的src需要在这里添加，res.path就是你服务器返回的图片链接。self.quill.insertEmbed(length, 'image', uploadConfig.fastDfsUrl+res.data);self.quill.setSelection(length + 1)}fileInput.value = ''};// 开始上传数据xhr.upload.onloadstart = function (e) {fileInput.value = ''};// 当发生网络异常的时候会触发，如果上传数据的过程还未结束xhr.upload.onerror = function (e) {};// 上传数据完成（成功或者失败）时会触发xhr.upload.onloadend = function (e) {// console.log('上传结束')};xhr.send(formData)});this.container.appendChild(fileInput);}fileInput.click();}
};export default {placeholder: '',theme: 'snow',  // 主题modules: {toolbar: {container: toolOptions,  // 工具栏选项handlers: handlers  // 事件重写}}
};

PS:

//这个js文件中以下3个地方需要修改
fastDfsUrl:'http://123.207.27.208',      	// 图片访问地址
action:  'http://localhost:8080/fastDfs', 	// 必填参数 图片上传地址
self.quill.insertEmbed(length, 'image', uploadConfig.fastDfsUrl+res.data); //data 服务器端图片的路径

2. 导入并使用

import quillConfig from '../../common/js/quill-config';
quillOption: quillConfig,// data数据模型中配置

三. 多图片上传

1. 数据库存储方式

例如t_pet中有个resources字段，专门用来保存宠物细节图片的，例如：

/group1/M00/00/0C/CgAIC2KrUU-ARA8EAAH2I5Y672k716.jpg,/group1/M00/00/0C/CgAIC2KrUYaAaR-6AADnxcxs4eA746.jpg,/group1/M00/00/0C/CgAIC2KrUYqAbjaZAAMbwtByyoU105.jpg,/group1/M00/00/0C/CgAIC2KrUY-AQcYWAAF5fdD2FCI302.jpg

PS:采用逗号分隔多张图片路径

2. 前端实现

<el-form-item label="宠物图片" prop="index"><el-upload class="upload-demo"action="http://localhost:8080/fastDfs/":on-preview="handlePreview":on-remove="handleRemove":on-success="handleSuccess":file-list="fileList"list-type="picture"><el-button size="small" type="primary">点击上传</el-button><div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div></el-upload>
</el-form-item>

3. 数据模型

//编辑界面数据
editForm: {id: null,typeId: null,name: '',state: 0,resources: '',saleprice: '',costprice: '',onsaletime: '',offsaletime: '',shopId: '',userId: '',petDetail: {  //与后端实体类一致id: null,intro: '',adoptNotice: ''}
},

4. 逻辑代码实现

//文件上传的业务逻辑
handleSuccess(response, file, fileList) {// 上传多张图片需要对resources进行处理,多张图片保存到数据库的resources字段用,隔开if (this.editForm.resources) {// 对已经存在的图片进行拼接this.editForm.resources = this.editForm.resources + "," + response.data} else {this.editForm.resources = response.data}console.log(this.editForm.resources)// 对fileList进行处理，用以显示图片// 先清空 - 这个fileList做了绑定，以前是有值【先清空，再添加最新的数据】this.fileList = []if (this.editForm.resources) {// /group1/M00/00/0C/CgAIC2KrUU-ARA8EAAH2I5Y672k716.jpg,/group1/M00/00/0C/CgAIC2KrUYaAaR-6AADnxcxs4eA746.jpg 对其进行分割let arr = this.editForm.resources.split(',')// 循环遍历for (let i = 0; i < arr.length; i++) {// 从fastDfs文件系统获取资源this.fileList.push({'url': 'http://123.207.27.208' + arr[i]})}}},//文件删除的业务逻辑
handleRemove(file, fileList) {// url:"http://123.207.27.208/group1/M00/01/D0/CgAIC2MwX7eAWEwlAACO89rfJDY938.jpg"console.log(file);const filePath = file.url.substring(file.url.indexOf('/group'))// /group1/M00/01/D0/CgAIC2MwX7eAWEwlAACO89rfJDY938.jpgthis.$http.delete("/fastDfs?path=" + filePath).then(res => {if (res.data.success) {this.$message.success("删除成功")} else {this.$message.error("删除失败")}});// 删除之后对resources做处理if (this.editForm.resources) {let arr = this.editForm.resources.split(',');for (let i = 0; i < arr.length; i++) {if (arr[i] == filePath) {//找到了删除的图片arr.splice(i, 1);//删除数组中指定的图片// 跳出循环break;}}// 对resources重新拼接this.editForm.resources = arr.join(',')}console.log("删除后的resources:" + this.editForm.resources);// 对fileList进行处理，用以显示图片// 先清空 - 这个fileList做了绑定，以前是有值【先清空，再添加最新的数据】this.fileList = []if (this.editForm.resources) {// /group1/M00/00/0C/CgAIC2KrUU-ARA8EAAH2I5Y672k716.jpg,/group1/M00/00/0C/CgAIC2KrUYaAaR-6AADnxcxs4eA746.jpg 对其进行分割let arr = this.editForm.resources.split(',')// 循环遍历for (let i = 0; i < arr.length; i++) {// 从fastDfs文件系统获取资源this.fileList.push({'url': 'http://123.207.27.208' + arr[i]})}}
},

5. 数据回显

//显示编辑界面
handleEdit: function (index, row) {this.title = '编辑'this.editForm = Object.assign({}, row);// 对fileList进行处理，用以显示图片// 先清空 - 这个fileList做了绑定，以前是有值【先清空，再添加最新的数据】this.fileList = []if (this.editForm.resources) {// /group1/M00/00/0C/CgAIC2KrUU-ARA8EAAH2I5Y672k716.jpg,/group1/M00/00/0C/CgAIC2KrUYaAaR-6AADnxcxs4eA746.jpg 对其进行分割let arr = this.editForm.resources.split(',')// 循环遍历for (let i = 0; i < arr.length; i++) {// 从fastDfs文件系统获取资源this.fileList.push({'url': 'http://123.207.27.208' + arr[i]})}}this.editFormVisible = true;
}this.fileList = []if (this.editForm.resources) {// /group1/M00/00/0C/CgAIC2KrUU-ARA8EAAH2I5Y672k716.jpg,/group1/M00/00/0C/CgAIC2KrUYaAaR-6AADnxcxs4eA746.jpg 对其进行分割let arr = this.editForm.resources.split(',')// 循环遍历for (let i = 0; i < arr.length; i++) {// 从fastDfs文件系统获取资源this.fileList.push({'url': 'http://123.207.27.208' + arr[i]})}}this.editFormVisible = true;
}
