一、HTML

<template><div class="taskInfo"><el-form:model="generateParams":rules="formRules"ref="formRef"class="taskInfoForm"label-width="100px"><ul class="taskInfoSearch"><li><el-form-item label="类型" prop="type"><el-selectv-model="generateParams.type"placeholder="请选择类型"><el-option :value="1" label="aaa"></el-option><el-option :value="2" label="bbb"></el-option></el-select></el-form-item></li><li><el-form-item label="开始" prop="start"><el-inputv-model="generateParams.start"placeholder="请输入开始值"></el-input></el-form-item></li><li><el-form-item label="结束" prop="end"><el-inputv-model="generateParams.end"placeholder="请输入结束值"></el-input></el-form-item></li><li><el-form-item label="开始时间" prop="startTime"><el-date-pickerv-model="generateParams.startTime"type="datetime"placeholder="请选择开始时间"format="YYYY/MM/DD hh:mm:ss"value-format="YYYY-MM-DD h:m:s" /></el-form-item></li><li><el-form-item label="结束时间" prop="endTime"><el-date-pickerv-model="generateParams.endTime"type="datetime"placeholder="请选择结束时间"format="YYYY/MM/DD hh:mm:ss"value-format="YYYY-MM-DD h:m:s" /></el-form-item></li></ul><div class="taskInfoAddBtn"><el-button type="primary" @click="addRowData">新增表格数据</el-button></div><div class="taskInfoTab"><el-table:data="generateParams.studentInfo":cell-class-name="cellClassName":row-class-name="rowClassName"@cell-click="cellClick"><el-table-column label="姓名"><template #default="{ row, column }"><el-form-item:prop="'studentInfo.' + row.index + '.name'":rules="formRules.name"v-if="row.index == rowIndex && column.index == columnIndex"><el-inputv-model.number="row.name"type="number"@blur="hideInput"v-focus></el-input></el-form-item><span v-else>{{ row.name }}</span></template></el-table-column><el-table-column label="年龄"><template #default="{ row, column }"><el-form-item:prop="'studentInfo.' + row.index + '.age'":rules="formRules.age"v-if="row.index == rowIndex && column.index == columnIndex"><el-inputv-model.number="row.age"type="number"@blur="hideInput"v-focus></el-input></el-form-item><span v-else>{{ row.age }}</span></template></el-table-column><el-table-column label="性别"><template #default="{ row, column }"><el-form-item:prop="'studentInfo.' + row.index + '.sex'":rules="formRules.sex"v-if="row.index == rowIndex && column.index == columnIndex"><el-inputv-model.number="row.sex"type="number"@blur="hideInput"v-focus></el-input></el-form-item><span v-else>{{ row.sex }}</span></template></el-table-column><el-table-column label="操作" width="100"><template #default="{ row }"><el-button type="danger" link @click="delRowData(row)">删除</el-button></template></el-table-column></el-table></div></el-form><div class="generate"><el-button type="primary" @click="generate(formRef)">任务信息生成</el-button></div><!-- 任务信息生成信息模态框 --><TaskInfoModel ref="TaskInfoModelRef"></TaskInfoModel></div>
</template>

二、JS

<script setup>
// -------------------<<模块引入>>-------------------
import { ref, reactive, onMounted, nextTick } from "vue";
import { ElMessage } from "element-plus";
// -------------------<<变量声明>>-------------------
// 生成参数
const generateParams = reactive({type: 1, // 类型start: 1000000000, // 开始end: 2000000000, // 结束startTime: "2024-08-05 15:33:55", // 开始时间endTime: "2024-08-15 15:33:55", // 结束时间studentInfo: [// 任务区域{name: 123.1122331, // 姓名age: 80.12345621, // 年龄sex: 1200.1, // 性别},{name: 114.1122331, // 姓名age: 80.12345621, // 年龄sex: 1200.1, // 性别},{name: 114.1122331, // 姓名age: 80.12345621, // 年龄sex: 1200.1, // 性别},],
});
// form表单规则
const formRules = reactive({type: [{ required: true, message: "请选择类型", trigger: "change" }],start: [{ required: true, message: "请输入开始", trigger: "blur" }],end: [{ required: true, message: "请输入结束", trigger: "blur" }],startTime: [{ required: true, message: "请选择开始时间", trigger: "change" }],endTime: [{ required: true, message: "请选择结束时间", trigger: "change" }],name: [{ required: true, message: "请输入姓名", trigger: "blur" }],age: [{ required: true, message: "请输入年龄", trigger: "blur" }],sex: [{ required: true, message: "请输入性别", trigger: "blur" }],
});
// 获取form表单ref
const formRef = ref();
// 行列index
const rowIndex = ref(null);
const columnIndex = ref(null);
// 是否允许编辑
const isEdit = ref(true);// -------------------<<函数定义>>-------------------
// 生成
const generate = (formEl) => {if (!formEl) return;formEl.validate((valid) => {if (valid) {console.log(generateParams);TaskInfoModelRef.value.openWin();} else {console.log("error submit!");//当验证失败跳转到空白的所在区域nextTick(() => {let isError = document.getElementsByClassName("is-error");isError[0].scrollIntoView({// 滚动到指定节点// 值有start,center,end，nearestblock: "center",// 值有auto、instant,smooth，缓动动画behavior: "smooth",});});return false;}});
};
// 表格单元格className回调方法
const cellClassName = ({ column, columnIndex }) => {column.index = columnIndex;
};
// 表格行className回调方法
const rowClassName = ({ row, rowIndex }) => {row.index = rowIndex;
};
// 表格单元格点击事件
const cellClick = (row, column) => {if (isEdit.value) {rowIndex.value = row.index;columnIndex.value = column.index;}
};
// input框失去焦点事件
const hideInput = (e) => {if (e.target.value) {rowIndex.value = null;columnIndex.value = null;isEdit.value = true;} else {isEdit.value = false;}
};
// 新增数据
const addRowData = () => {generateParams.studentInfo.push({name: "",age: "",sex: "",});
};
// 删除本行数据
const delRowData = (row) => {if (generateParams.studentInfo.length > 1) {generateParams.studentInfo.splice(row.index, 1);} else {ElMessage.warning("最少保留1条数据");}
};
// -------------------<<函数执行>>-------------------
onMounted(() => {});
</script>

三、CSS

<style lang="less" scoped>
.taskInfo {width: 100%;height: 100%;:deep(.taskInfoForm) {width: 100%;height: calc(100% - 80px);.taskInfoSearch {width: 100%;height: 120px;display: flex;align-items: center;flex-wrap: wrap;li {width: 25%;height: 50%;.el-form-item__label {color: #fff;}.el-form-item {width: 100%;height: 100%;margin-bottom: 0px;display: flex;align-items: center;.el-date-editor.el-input,.el-input,.el-select {width: 100% !important;}}}}.taskInfoAddBtn {width: 100%;height: 50px;display: flex;align-items: center;justify-content: flex-end;}.taskInfoTab {width: 100%;height: calc(100% - 170px);position: relative;.el-table {width: 100%;height: 100%;background: transparent !important;position: absolute;.el-form-item {width: 100%;margin-bottom: 0px;.el-form-item__content {margin-left: 0px !important;display: flex;align-items: center;justify-content: center;.el-input,.el-select {width: 80% !important;}}}td,th {text-align: center;}}}}.generate {width: 100%;height: 80px;display: flex;align-items: center;justify-content: center;}
}
</style>
