现在的需求是：实现一个项目展示模块，后端管理页面除了需要基础信息外，要加上一个图片上传和富文本框编辑器功能。
二、效果点击”图片存储地址”：可上传电脑任何位置的图片，并可对图片进行放大，缩小，和旋转。
存入数据库的图片以url地址存放 url直接百度可看到图片：
三、编码过程1.前端：index.vue<template> <div class="app-container"> <!-- 新增项目 --> <el-row :gutter="10" class="mb8"> <el-col :span="1.5"> <el-button type="primary" plain icon="el-icon-plus" size="mini" @click="handleAdd" >新增 </el-button> </el-col> </el-row> <!-- 添加或修改项目展示 --> <el-dialog :title="title" :visible.sync="open" width="1000px" append-to-body> <el-form ref="formObj" :model="form" :rules="rules" label-width="120px" > <el-form-item label="项目名称" prop="projectName"> <el-input v-model="form.projectName" placeholder="请输入项目名称" /> </el-form-item> <el-form-item label="项目类型" prop="projectType"> <el-select v-model="form.projectType" placeholder="请选择项目类型" style="width: 65%" > <el-option v-for="dict in projectTypeOptions" :key="dict.dictValue" :label="dict.dictLabel" :value="dict.dictValue" ></el-option> </el-select> </el-form-item> <el-form-item prop="picUrl" label="图片存储地址" required> <div class="coverImg-upload" @click="showCoverImgCropper = true"> <img v-if="form.picUrl" :src="form.picUrl" class="coverImg" /> <i v-else class="el-icon-plus coverImg-upload-icon" /> </div> </el-form-item> <el-form-item prop="projectDetail" label="项目详情"> <my-quill-editor v-model="form.projectDetail" ref="quillEditor" /> </el-form-item> <el-form-item label="备注" prop="remark"> <el-input v-model="form.remark" type="textarea" placeholder="请输入备注" /> </el-form-item> </el-form> <img-upload-cropper :visible.sync="showCoverImgCropper" @upload-success="onCoverImgUploaded" /> <div slot="footer" class="dialog-footer"> <el-button type="primary" @click="submitForm">确 定</el-button> <el-button @click="cancel">取 消</el-button> </div> </el-dialog> <!-- 项目展示平台查询 --> <el-table v-loading="loading" :data="projectShowList" row-key="id" default-expand-all :tree-props="{ children: 'children', hasChildren: 'hasChildren' }" > <el-table-column label="项目名称" align="center" prop="projectName" /> <el-table-column label="图片存储地址" align="center" prop="picUrl" v-if="false" /> <el-table-column label="项目详情" align="center" prop="projectDetail" v-if="false" /> <el-table-column label="项目类型" align="center" prop="projectType" :formatter="projectTypeFormat" /> <el-table-column label="创建人" align="center" prop="createUser" /> <el-table-column label="创建时间" align="center" prop="createTime" /> <el-table-column label="修改人" align="center" prop="updateUser" /> <el-table-column label="修改时间" align="center" prop="updateTime" /> <el-table-column label="备注" align="center" prop="remark"/> <el-table-column label="操作" align="center" class-name="small-padding fixed-width" > <template slot-scope="scope"> <el-button size="mini" type="text" icon="el-icon-edit" @click="handleUpdate(scope.row)" >修改</el-button > <el-button size="mini" type="text" icon="el-icon-delete" @click="handleDelete(scope.row)" >删除</el-button > </template> </el-table-column> </el-table> </div></template> <script>import { listProjectShow, addProjectShow, updateProjectShow, getProjectShow, delProjectShow,} from "@/api/projectShow/projectShow";import myQuillEditor from "@/components/Editor";import ImgUploadCropper from "@/components/ImgUploadCropper";export default { name: "cpsp", components: { myQuillEditor, ImgUploadCropper, }, data() { return { // 遮罩层 loading: true, // 资产分类表格数据 projectShowList: [], //计费方式字典 projectTypeOptions: [], // 弹出层标题 title: "", // 资产分类树选项 categoryOptions: [], // 是否显示弹出层 open: false, // 表单参数 form: { id: null, projectName: null, projectType: "1", picUrl: "", projectDetail: "", remark: null, }, showCoverImgCropper: false, formObj: "", // 表单校验 rules: { projectName: [ { required: true, message: "项目名称不能为空", trigger: "blur" }, ], projectType: [ { required: true, message: "项目类型不能为空", trigger: "blur" }, ], picUrl: [ { required: true, trigger: "change", message: "图片存储地址不能为空" }, ], }, };
