一、导入
0、关键代码
// 安装插件
npm i xlsx/yarn add xlsx
// 导入xlsx
import * as XLSX from 'xlsx';
点击提交的时候才整理数据。上传的时候文件保存在 state.form.file[0] 中的
// 定义字段映射关系
const fieldMap = {sheet2json: {技能名称: 'skill_name',技能等级: 'skill_level',技能描述: 'skill_desc',技能类型: 'skill_type',技能效果: 'skill_effect',技能消耗: 'skill_cost',技能持续时间: 'skill_duration',技能范围: 'skill_range',技能范围: 'skill_range',技能目标: 'skill_target'}
};// 提交 --- 点击提交的时候才整理数据。上传的时候文件保存的 state.form.file[0] 中的
const handleSummit = () => {formRef.value.validate().then(async () => {try {const data = await state.form.file[0].arrayBuffer(); // 使用 arrayBuffer 避免中文乱码const workbook = XLSX.read(data, { type: 'buffer' });const outdata = XLSX.utils.sheet_to_json(workbook.Sheets[workbook.SheetNames[0]]);// 映射字段名并过滤掉不符合预期的数据const mappedData = outdata.map(row => {return Object.keys(row).reduce((targetMap, key) => {const mappedKey = fieldMap.sheet2json[key];if (mappedKey) {targetMap[mappedKey] = row[key];}return targetMap;}, {});}).filter(item => Object.keys(item).length > 0); // 过滤空对象console.log('------- 导入的数据 -------', mappedData);emits('submit', mappedData);handleClose();} catch (error) {}});
};
1、template
<a-form :model="state.form" name="form" ref="formRef" :label-col="{ style: { width: '120px' } }" autocomplete="off" :rules="rules"><a-form-item label="导入文件上传" name="file" :rules="rules.file"><div class="file-warp" style="position: relative"><a-uploadstyle="margin-left: 20px":file-list="state.form.file"name="file":customRequest="upload":beforeUpload="beforeUpload"@remove="handleRemove"accept=".xlsx, .xls"><a-button type="primary"><upload-outlined></upload-outlined>上传文件</a-button></a-upload><a-button type="primary" ghost style="position: absolute; top: 0; left: 150px" @click="handleDownload"><VerticalAlignBottomOutlined></VerticalAlignBottomOutlined>模版下载</a-button></div></a-form-item>
</a-form>
2、script
import * as XLSX from 'xlsx';
import { reactive, ref } from 'vue';const state = reactive({form: {file: []}
});
const formRef = ref(null);
const open = ref(true);const rules = {file: [{ required: true, message: '请选择文件', trigger: ['blur', 'change'] }]
};// 定义字段映射关系
const fieldMap = {sheet2json: {技能名称: 'skill_name',技能等级: 'skill_level',技能描述: 'skill_desc',技能类型: 'skill_type',技能效果: 'skill_effect',技能消耗: 'skill_cost',技能持续时间: 'skill_duration',技能范围: 'skill_range',技能范围: 'skill_range',技能目标: 'skill_target'},json2sheet: {skill_name: '技能名称',skill_level: '技能等级',skill_desc: '技能描述',skill_type: '技能类型',skill_effect: '技能效果',skill_cost: '技能消耗',skill_duration: '技能持续时间',skill_range: '技能范围',skill_target: '技能目标'}
};// 上传文件之前检测
const beforeUpload = file => {const isXlsxOrXls = file.name.split('.')[1] == 'xlsx' || file.name.split('.')[1] == 'xls';if (!isXlsxOrXls) {message.error('只允许上传xlsx, xls格式的文件!');return false;}const isLt10M = file.size / 1024 / 1024 < 10;if (!isLt10M) {message.error('文件不得大于10MB!');return false;}return isXlsxOrXls && isLt10M;
};// 选择文件
const upload = file => {// 原本调用接口上传的// uplaodFile(file.file).then(res => {// fileList.value.push({ name: res.data.originalFilename, url: viteConfig.baseUrl + res.data.fileName, fileUrl: res.data.fileName });// formRef.value.clearValidate();// });state.form.file = [file.file];formRef.value.clearValidate();
};// 移除文件
const handleRemove = file => {state.form.file = [];
};// 提交 转换数据
const handleSummit = () => {formRef.value.validate().then(async () => {try {const data = await state.form.file[0].arrayBuffer(); // 使用 arrayBuffer 避免中文乱码const workbook = XLSX.read(data, { type: 'buffer' });const outdata = XLSX.utils.sheet_to_json(workbook.Sheets[workbook.SheetNames[0]]);// 映射字段名并过滤掉不符合预期的数据const mappedData = outdata.map(row => {return Object.keys(row).reduce((targetMap, key) => {const mappedKey = fieldMap.sheet2json[key];if (mappedKey) {targetMap[mappedKey] = row[key];}return targetMap;}, {});}).filter(item => Object.keys(item).length > 0); // 过滤空对象console.log('------- 导入的数据 -------', mappedData);emits('submit', mappedData);handleClose();} catch (error) {}});
};
二、模板下载
1、script
// 定义字段映射关系
const fieldMap = {json2sheet: {skill_name: '技能名称',skill_level: '技能等级',skill_desc: '技能描述',skill_type: '技能类型',skill_effect: '技能效果',skill_cost: '技能消耗',skill_duration: '技能持续时间',skill_range: '技能范围',skill_target: '技能目标'}
};// 模板数据
let templateData = [{skill_name: '大刀斩',skill_level: '5',skill_desc: '技能描述',skill_type: '大招',skill_effect: '亚瑟王那样的大招',skill_cost: '10000',skill_duration: '10',skill_range: '500',skill_target: '目标:亚瑟王'}
];// 模版下载
const handleDownload = () => {// 映射字段名并过滤掉不符合预期的数据const list = templateData.map(row => {return Object.keys(row).reduce((targetMap, key) => {const mappedKey = fieldMap.json2sheet[key];if (mappedKey) {targetMap[mappedKey] = row[key];}return targetMap;}, {});}).filter(item => Object.keys(item).length > 0); // 过滤空对象;const workSheet = XLSX.utils.json_to_sheet(list);const workBook = XLSX.utils.book_new();XLSX.utils.book_append_sheet(workBook, workSheet, '技能表');// 生成Excel文件并下载XLSX.writeFile(workBook, '技能表模板.xlsx');
};
