1.引入

本次框架是Ruoyi-plus+vue2+element组合。

2.样式

由于是后台项目，样式要求统一，不可以有的输入框长有的短。着重几点：

1.关于form表单应该如何水平布局

在element中，form有个属性叫：:inline="true"时候就会水平。但是有问题有的输入框比较长，像日期选择器和普通输入框大小就不一致。此时就不应该使用这个属性。应该用el-row,el-col。因为输入框默认是独占一行的就像div

代码如下

 <el-form :model="queryParams" ref="queryForm" label-width="80px"><el-row :gutter="20"><el-col :span="8"><el-form-item label="考核年度" prop="appraisalYear"><el-date-pickerv-model="queryParams.appraisalYear"type="year"placeholder="选择年"value-format="yyyy-MM-dd"></el-date-picker></el-form-item></el-col><el-col :span="8"><el-form-item label="负责人" prop="userId"><el-select v-model="queryParams.userId" placeholder="请选择"><el-optionv-for="(item, index) in userList":key="index":label="item.nickName":value="item.userId"></el-option></el-select></el-form-item></el-col><el-col :span="8"><el-button type="primary" icon="el-icon-search" @click="handleQuery">查询</el-button><el-button icon="el-icon-refresh-right" @click="resetQuery">重置</el-button></el-col></el-row></el-form>

2.当form表单过多时，如何布局

添加一个模板 <template v-if="advanced">利用advanced去控制遮住还是隐藏

    <el-form :model="queryParams" ref="queryForm" label-width="80px"><el-row :gutter="20"><el-col :span="8"><el-form-item label="时间" prop="date"><el-date-pickerv-model="queryParams.date"type="daterange"range-separator="至"start-placeholder="开始日期"end-placeholder="结束日期"></el-date-picker></el-form-item></el-col><el-col :span="8"><el-form-item label="名称" prop="taskName"><el-inputv-model="queryParams.taskName"placeholder="请输入"clearable/></el-form-item></el-col><template v-if="advanced"><el-col :span="8"><el-form-item label="紧急程度" prop="level"><el-select v-model="queryParams.level" placeholder="请选择"><el-option label="一般" value="0"></el-option><el-option label="急" value="1"></el-option><el-option label="紧急" value="2"></el-option></el-select></el-form-item></el-col><el-col :span="8"><el-form-item label="阅读状态" prop="isRead"><el-select v-model="queryParams.isRead" placeholder="请选择"><el-option label="未读" value="0"></el-option><el-option label="已读" value="1"></el-option></el-select></el-form-item></el-col><el-col :span="8"><el-form-item label="任务状态" prop="status"><el-select v-model="queryParams.status" placeholder="请选择"><el-option label="未开始" value="0"></el-option><el-option label="进行中" value="1"></el-option><el-option label="已提交" value="2"></el-option><el-option label="已完成" value="3"></el-option></el-select></el-form-item></el-col></template><el-col :span="8"><div style="margin-left: 30px"><el-button type="primary" icon="el-icon-search" @click="handleQuery">查询</el-button><el-button icon="el-icon-refresh-right" @click="resetQuery">重置</el-button><a @click="toggleAdvanced" style="margin-left: 16px">{{ advanced ? "收起" : "展开" }}<i:class="advanced ? 'el-icon-arrow-up' : 'el-icon-arrow-down'"></i></a></div></el-col></el-row></el-form>

3.业务逻辑

重点！！！先说说详情，编辑，行复制，删除，导入，导出，多选框的表格，单选框的表格，时间搜索，vue2数组和表单数据的渲染，文件的回显，图片的回显，还有es6语法，js逻辑。

1.详情

详情的话可以取决于你的页面是否和新增长的一样，如果长的一样，可以表单控制一个disabled属性来控制禁止输入

例子

 <el-form-item label="考核年度" prop="fulfillYear"><el-date-pickerv-model="form.fulfillYear"type="year"placeholder="选择年度"value-format="yyyy":disabled="disabled"></el-date-picker></el-form-item>

2.新增

外层的新增和编辑我会使用一个页面，没啥好说的。重点是内层新增她还可以编辑这个重点。如何编辑完可以拿到回调的值，这个难。

在编辑的页面增加一个标识符判断编辑还是新增

 save() {console.log("this.form", this.form);// this.$emit("getList", this.form);this.$emit("getList", {...this.form,addType: this.title === "新增考评指标" ? "add" : "edit",time: new Date().getTime(),});this.innerVisible = false;},

在新增的页面判断是新增还是编辑

    getList(value) {let newAddData = [];console.log("我收到了子组件新增标准的值", value);if (value.addType === "edit") {// 创建一个与this.tableData相同结构和内容的新数组// 使用JSON.parse(JSON.stringify(object))来深拷贝对象，避免直接修改原对象let marr = JSON.parse(JSON.stringify(this.tableData));// marr.forEach((item, index) => {//   if (index == value.index) {//     item = value;//   }// });marr[value.index] = value;console.log(marr);this.tableData = marr;console.log(marr);} else {if (Array.isArray(value)) {newAddData = [...this.tableData, ...value];} else {// 若 res.data 不是数组，将其包装成数组再进行合并newAddData = [...this.tableData, value];}// const newList = [...this.tableData, value];this.tableData = newAddData;// this.tableData.sort((a, b) => {//   // 先按照sort字段降序排序//   if (a.sort !== b.sort) {//     return a.sort - b.sort;//   } // 如果sort相同，则按照time字段升序排序（转换为毫秒）//   else {//     return b.time - a.time;//   }// });}// const newList = [...this.tableData, value];// this.tableData = newList;console.log("this.tableData", this.tableData);console.log("this.deptOptions", this.deptOptions);// 遍历tableData数组，根据deptId查找对应的labelthis.tableData = this.tableData.map((item) => {const deptName = this.findLabelById(item.deptId, this.deptOptions);const userIds = item.userIds?.split(",");if (userIds) {const userNames = userIds.map((item2) => {const user = this.userList.find((item3) => item3.userId === item2);// console.log("userNames", userNames);return user ? user.nickName : null;}).join(",");return { ...item, deptName, userNames };} else {return { ...item, deptName };}});console.log("this.tableData", this.tableData);},

这边要注意什么是浅拷贝和深拷贝，我之前都是浅拷贝，这边要改成深拷贝，深拷贝的话避免直接修改原对象。

3.编辑

编辑的话，通常后台需要传当前行的数据进去，后端会提供一个id,去查找数据，数据回显就好了。主要是文件和图片的回显看下面

4.行复制

代码如下深拷贝一个对象这样不会影响原对象， delete copy.createTime;删除对象属性 es6语法，这边的逻辑就是复制一个和原对象无关的对象，然后用接口新增。这边重点是es6语法和深浅拷贝的了解与引用

1.深拷贝

const copy = JSON.parse(JSON.stringify(row));

2. 浅拷贝

 const copy = Object.assign({}, row);

如果修改的是第一层（直接）属性且它们是原始类型，row 不受影响；
如果修改的是第一层（直接）属性且它们是引用类型（如其他对象或数组），实际上是在修改共享的嵌套对象，此时 row 会相应地发生改变。
例子如下

const row = {name: 'John',address: {street: 'Main St.',number: 123,},
};const copy = Object.assign({}, row);// 修改第一层属性（字符串），不影响 row
copy.name = 'Jane'; // row.name仍然是'John'// 修改嵌套对象的属性，会影响 row
copy.address.street = 'New St.'; // row.address.street现在也是'New St.'

 async copyRow(row) {console.log("row", row);// this.loading = true;const copy = JSON.parse(JSON.stringify(row));delete copy.createTime;copy.dutyAppraisalId = null;copy.status = nullcopy.isRead = 0copy.progress = 0console.log("copy", copy);await this.getDetail(row.dutyAppraisalId);addDemo({status: 0,type: 0,...copy,dutyItems: this.tableData,}).then((res) => {if (res.code == 200) {this.$message({message: "新建成功",type: "success",});this.loading = false;this.getList();}});// .finally(() => {//   this.loading = false;// });},

5.删除

在这个项目中有3中删除

第一种：利用接口拿到id，接口删除

  del(No, data) {// console.log("No", No, "DATA", data);if (data.workItemId) {delDetailList(data.workItemId).then((res) => {if (res.code == 200) {this.$message({message: "删除成功",type: "success",});this.deleteFuc(No, data);}});} else {this.deleteFuc(No, data);}},

第二种：不需要调用接口时候，利用filter es6的语法

 // 使用数组的filter方法，传入一个回调函数作为筛选条件// 回调函数接受当前遍历项（item）作为参数，检查其"No"属性是否与传入的No参数相异// 若相异则保留该项，否则过滤掉const filterData = this.originalData.filter((item) => {return item.No !== No;});

第三种：直接用数组splice

      this.fileList.splice(index, 1);

6.导入

三部曲

第一步：

 <el-uploadclass="upload-demo":action="uploadFileUrl"multiple:show-file-list="false":headers="headers":on-success="handleUploadSuccess"><el-button>导入</el-button></el-upload>

第二步：定义， id不存在，存在，不确定存不存在的写法都在下方

import { getToken } from "@/utils/auth";
export default {components: { contentSet, editStandard },data() {return {activeName: "first",activeName2: "first",form: {},title: "",dialogVisible: false,// 接收数据tableData: [],updatedData: [],// 字典值List: [],showData: [], //展示数据originalData: [], //真正的数据// rowData: {}, //行数据uploadFileUrl: `${process.env.VUE_APP_BASE_API}/epb/workItem/importData${this.form && this.form.id ? "?workId=" + this.form.id : ""}`,// uploadFileUrl: `${process.env.VUE_APP_BASE_API}/epb/workItem/importData?workId=${this.form.id}`, // 上传文件服务器地址// uploadFileUrl: process.env.VUE_APP_BASE_API + "/epb/workItem/importData", // 上传文件服务器地址headers: {Authorization: "Bearer " + getToken(),},show: false,workList: [],loading: false,};},

第三步：

 // 导入文件handleUploadSuccess(res, file) {// console.log("res", res, "file", file);if (res.code == 200) {//深拷贝let mArr = JSON.parse(JSON.stringify(tableData));// 页面操作  concat() 方法用于合并两个或多个数组。此方法不会更改现有数组，而是返回一个新数组。mArr = mArr.concat(res.data.workItemVos);mArr = mArr.map((item, index) => {return {...item,sort: item.sort + 1, //一开始就遍历加上序号markTime: new Date().getTime(),};});// console.log("mArr", mArr);this.getContentList(mArr);// this.workList = [];this.workList = this.workList.concat(res.data.workLabelVos);console.log("this.workList", this.workList);}},

7.导出

 <el-buttontype="primary"plainicon="el-icon-download"@click="handleExport">导出</el-button>/** 导出按钮操作 */handleExport() {this.download("/epb/dutyFulfill/export",{...this.queryParams,},`责任落实档案列表.xlsx`);},

8.多选框的表格

9.单选框的表格

10.时间搜索

    getList() {// this.getTime();let mData = Object.assign({pageNum: this.pagination.current,pageSize: this.pagination.pageSize,},// this.queryParams{...this.queryParams,startTime: this.queryParams?.date?.length ? dayjs(this.queryParams.date[0]).format("YYYY-MM-DD") : undefined,endTime: this.queryParams?.date?.length > 1 ? dayjs(this.queryParams.date[1]).format("YYYY-MM-DD") : undefined,});mData.createUserId = store.getters.userId;this.loading = true;listDemo(mData).then((res) => {if (res.code == 200) {console.log("res", res);this.remindersList = res.rows;console.log("this.remindersList", this.remindersList);this.pagination.total = res.total;this.loading = false;}}).finally(() => {this.loading = false;});},

11.对象的键名

   //         const obj = {//             a: 1,//             b: 2,//             c: []//           }//           obj['c']就是数组，拿到的是obj.c的值，可以用push

  groupAndMergeData(arr) {// console.log("a2222", arr);let groupedData = {}; // 遍历newAddData，按workContent字段分类arr.forEach((item) => {//         const obj = {//             a: 1,//             b: 2,//             c: []//           }//           obj['c']就是数组，拿到的是obj.c的值，可以用pushif (!groupedData[item.workContent]) {// [item.workContent]表示键名groupedData[item.workContent] = [item];} else {groupedData[item.workContent].push(item);// groupedData[item.workContent].sort((a, b) => a.sort - b.sort);groupedData[item.workContent].sort((a, b) => {// 先按照sort字段降序排序if (a.sort !== b.sort) {return a.sort - b.sort;} // 如果sort相同，则按照time字段升序排序（转换为毫秒）else {return b.markTime - a.markTime;}});}});// console.log("arr11111", arr);// console.log("groupedData", groupedData);// 合并所有子数组let mergedData = [];for (let category in groupedData) {mergedData = [...mergedData, ...groupedData[category]];}// console.log("mergedData", mergedData);// 全部数据保存到这个真正的数据里const sortData = [...mergedData].map((item, index) => {return {...item,No: index + 1, //一开始就遍历加上序号};});return sortData;},

分组一种是对象的分组，一种的数组的分组

数组的分组

  let classifyWorkContentList = []; //类别数组[...sourceData].forEach((item) => {// .includes()方法返回一个布尔值（true或false）if (classifyWorkContentList.indexOf(item.workContent) === -1) {classifyWorkContentList.push(item.workContent);}});

12.文件的回显

  const fileArr =data?.fileUrl?.split(",")?.map((item, index) => {return {fileUrl: item,fileName: data?.fileName?.split(",")[index],};}) || [];this.form = data;this.$set(this.form, "fileList", fileArr);<el-descriptions-item label="附件" :span="2"><span v-for="(item, index) in form.fileList" :key="index"><a :href="item.fileUrl" target="_blank">{{ item.fileName }}</a>,</span></el-descriptions-item>

这边的index因为fileUrl和fileName不是一个数组里的,俩个本来是俩个字符串，然后用split分隔成俩个数组，这边的操作就是把它们弄到一个数组里

13.图片的回显

<template><div><el-image v-for="(item,index) in realSrcList" :key="index":src="`${item}`"fit="cover":style="`width:${realWidth};height:${realHeight};`":preview-src-list="realSrcList"><div slot="error" class="image-slot"><i class="el-icon-picture-outline"></i></div></el-image></div></template><script>export default {name: "ImagePreview",props: {src: {type: String,default: ""},width: {type: [Number, String],default: ""},height: {type: [Number, String],default: ""}},computed: {realSrc() {if (!this.src) {return;}let real_src = this.src.split(",")[0];return real_src;},realSrcList() {if (!this.src) {return;}let real_src_list = this.src.split(",");let srcList = [];real_src_list.forEach(item => {return srcList.push(item);});return srcList;},realWidth() {return typeof this.width == "string" ? this.width : `${this.width}px`;},realHeight() {return typeof this.height == "string" ? this.height : `${this.height}px`;}},
};
</script><style lang="scss" scoped>
.el-image {border-radius: 5px;background-color: #ebeef5;box-shadow: 0 0 5px 1px #ccc;::v-deep .el-image__inner {transition: all 0.3s;cursor: pointer;&:hover {transform: scale(1.2);}}::v-deep .image-slot {display: flex;justify-content: center;align-items: center;width: 100%;height: 100%;color: #909399;font-size: 30px;}
}
</style>

父组件

 <ImagePreview:src="form.picUrl":width="150":height="150"></ImagePreview>

14.es6语法

map,filter

15.js逻辑关于党务工作清单的

第一步：要先判断是编辑还是新增。第二步：要确定传给后端的格式。第三步：展示数据的格式。第四步：删除的排序要判断是有id的还是直接删除。第五步：当导入进来的时候，相当于新增，要进行，说明新增的时候要进行判断，如果是数据还是对象。第六步：对于这种提交数据和展示数据不一样数据格式时候要注意操作。

第一步：

  getContentList(value) {// console.log("我收到子组件传递的值", value);let newData = [];let newAddData = [];if (value.addType === "edit") {// console.log("this.originalData", this.originalData);newData = this.originalData.map((item) => {if (item.No === value.No) {return value;}return item;});} else {if (Array.isArray(value)) {newData = [...this.originalData, ...value];} else {// 若 res.data 不是数组，将其包装成数组再进行合并newData = [...this.originalData, value];}}// console.log("value111", value);// console.log("更新后的newData:", newData);const sortData = this.groupAndMergeData(newData);// 赋值给真正的数组this.originalData = sortData;// console.log("sortData时间字段", sortData);// 赋值给展示数据this.showData = this.handleData(sortData);},

数据分类

   // 分类排序groupAndMergeData(arr) {// console.log("a2222", arr);let groupedData = {}; // 遍历newAddData，按workContent字段分类arr.forEach((item) => {//         const obj = {//             a: 1,//             b: 2,//             c: []//           }//           obj['c']就是数组，拿到的是obj.c的值，可以用pushif (!groupedData[item.workContent]) {// [item.workContent]表示键名groupedData[item.workContent] = [item];} else {groupedData[item.workContent].push(item);// groupedData[item.workContent].sort((a, b) => a.sort - b.sort);groupedData[item.workContent].sort((a, b) => {// 先按照sort字段降序排序if (a.sort !== b.sort) {return a.sort - b.sort;} // 如果sort相同，则按照time字段升序排序（转换为毫秒）else {return b.markTime - a.markTime;}});}});// console.log("arr11111", arr);// console.log("groupedData", groupedData);// 合并所有子数组let mergedData = [];for (let category in groupedData) {mergedData = [...mergedData, ...groupedData[category]];}// console.log("mergedData", mergedData);// 全部数据保存到这个真正的数据里const sortData = [...mergedData].map((item, index) => {return {...item,No: index + 1, //一开始就遍历加上序号};});return sortData;},

重点是对象键名变数组

  //         const obj = {//             a: 1,//             b: 2,//             c: []//           }//           obj['c']就是数组，拿到的是obj.c的值，可以用push

展示数据处理

 // 处理数据handleData(sourceData) {// 分类let classifyWorkContentList = []; //类别数组[...sourceData].forEach((item) => {// .includes()方法返回一个布尔值（true或false）if (classifyWorkContentList.indexOf(item.workContent) === -1) {classifyWorkContentList.push(item.workContent);}});console.log("classifyWorkContentList", classifyWorkContentList);// 按照表格样式修改数据结构// 例如[{workContent: 'xxx', workNormList: [{workItemId: 1111,workId: 11111 ,workContent:'xxx',sort: 1,workNorm:'xxx',No: 1,isDone: 0}]const handleData = classifyWorkContentList.map((item) => {return {workContent: item,workNormList: sourceData.filter((item2) => item2.workContent === item),};});return handleData;},

删除数据

    deleteFuc(No, data) {const filterData = this.originalData.filter((item) => {return item.No !== No;});const sortData = filterData.map((item, index) => {return {...item,No: index + 1, //一开始就遍历加上序号};});this.originalData = sortData;// 赋值给展示数据this.showData = this.handleData(sortData);},// 删除del(No, data) {// console.log("No", No, "DATA", data);if (data.workItemId) {delDetailList(data.workItemId).then((res) => {if (res.code == 200) {this.$message({message: "删除成功",type: "success",});this.deleteFuc(No, data);}});} else {this.deleteFuc(No, data);}},

导入文件

 // 导入文件handleUploadSuccess(res, file) {// console.log("res", res, "file", file);if (res.code == 200) {const tableData = [];let mArr = JSON.parse(JSON.stringify(tableData));// 页面操作  concat() 方法用于合并两个或多个数组。此方法不会更改现有数组，而是返回一个新数组。mArr = mArr.concat(res.data.workItemVos);mArr = mArr.map((item, index) => {return {...item,sort: item.sort + 1, //一开始就遍历加上序号markTime: new Date().getTime(),};});// console.log("mArr", mArr);this.getContentList(mArr);// this.workList = [];this.workList = this.workList.concat(res.data.workLabelVos);console.log("this.workList", this.workList);}},

16.树形下拉框

子组件

<template><div><a-tree-selectv-model="orgId"style="width: 100%"size="large":dropdown-style="{ maxHeight: '400px', overflow: 'auto', zIndex: 3000 }"placeholder="请选择"allow-cleartree-default-expand-all:disabled="disabled":tree-data="vorganTreeData":replaceFields="replaceFields"@change="onChange"></a-tree-select></div>
</template><script>
//注意！！！！！
//在modal弹窗组件中使用该组件需要在关闭弹窗方法里清空数据否则会报错
import { userdepList } from "@/api/user/user";
export default {name: "vorganTree",props: {value: {// 如果希望value可以接收int类型的值而不报错，可以将type类型修改为可以兼容字符串和整数的类型type: [String, Number],default: "",},disabled: {type: Boolean,default: false,},replaceFields: {type: Object,default: () => {return {children: "children",title: "label",key: "id",value: "id",};},},},data() {return {orgId: this.value,vorganTreeData: [],deptId: "",};},watch: {value: {handler(newVal) {this.orgId = newVal;},immediate: true,},},mounted() {// this.$bus.$on("id", (data) => {//   console.log("我是任务组件,收到了数据", data);//   this.deptId = data;// });this.deptId = this.$bus.id;this.userdepList();},methods: {userdepList() {userdepList({ ancestors: this.deptId }).then((res) => {console.log("res.data", res);this.vorganTreeData = res.data;});},selectClear() {this.orgId = undefined;},onChange(value, item, xx) {console.log(11111, value, item, xx);// this.$emit("update:value", value);this.$emit("getdep", value);},},
};
</script><style scoped lang="less">
</style>

父组件

      <orginTree v-model="form.deptId" @getdep="getdep"></orginTree>

17.时间的回显

this.$set(this.form, "date", [dayjs(data.startTime).format("YYYY-MM-DD"),dayjs(data.endTime).format("YYYY-MM-DD"),]);

18.富文本去除标签富文本组件事Editor

    <Editor v-model="form.requirement" :height="100"></Editor>// 提交数据时去除<p>标签const processedRequirement = that.form.requirement?.replace(/<\/?p>/g,"");

19.props接收兼容性写法

 props: {value: {// 如果希望value可以接收int类型的值而不报错，可以将type类型修改为可以兼容字符串和整数的类型type: [String, Number],default: "",},disabled: {type: Boolean,default: false,},replaceFields: {type: Object,default: () => {return {children: "children",title: "label",key: "id",value: "id",};},},},

20.文本的总体代码
