注意:vue中要实现表格的导入与导出,首先要install两个依赖,
npm install -S file-saver xlsx 和 npm install -D script-loader。其次,在项目src目录下新建一个文件夹vendor(名字随意),在此文件夹下放置两个文件Blob.js和Export2Excal.js(下载地址:http://files.cnblogs.com/files/luyuefeng/vendor.rar)。之后就可以愉快的导入导出了。
1、导入
<input id="upload" type="file" @change="importfxx()" accept=".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" />
importfxx(obj) { let _this = this; let inputDOM = this.$refs.inputer; // 通过DOM取文件数据 this.file = event.currentTarget.files[0]; var rABS = false; //是否将文件读取为二进制字符串 var f = this.file; var reader = new FileReader(); FileReader.prototype.readAsBinaryString = function(f) { var binary = ""; var rABS = false; //是否将文件读取为二进制字符串 var pt = this; var wb; //读取完成的数据 var outdata; var reader = new FileReader(); reader.onload = function(e) { var bytes = new Uint8Array(reader.result); var length = bytes.byteLength; for(var i = 0; i < length; i++) { binary += String.fromCharCode(bytes[i]); } var XLSX = require('xlsx'); if(rABS) { wb = XLSX.read(btoa(fixdata(binary)), { //手动转化 type: 'base64' }); } else { wb = XLSX.read(binary, { type: 'binary' }); } outdata = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]); let importList = _this.dateTransition(outdata); } reader.readAsArrayBuffer(f); } if(rABS) { reader.readAsArrayBuffer(f); } else { reader.readAsBinaryString(f); } };
// 将对应的中文key转化为自己想要的英文key dateTransition(outdata) { let list = []; var obj = {}; for(var i = 0; i < outdata.length; i++) { obj = {}; for(var key in outdata[i]) { if(key == '工号') { obj['jobNumber'] = outdata[i][key]; } else if(key == '姓名') { obj['name'] = outdata[i][key]; } else if(key == '部门') { obj['department'] = outdata[i][key];
}
}
list.push(obj); } return list; };
例如:现有一张excel表格需要导入。
导入后,获取到的outdata为
outdata = [
{
"姓名": "张三",
"工号": "1001",
"部门": "技术部"
},
{
"姓名": "李四",
"工号": "1002",
"部门": "技术部"
},
];
这里获取到outdata的json格式的key值对应的是导入的excel表格中的表头名称,往往都是中文的,要想把中文key转化为自己想要的英文key就需要用到dateTransition函数了。
通过dateTransition函数转化后对应的importList变为
importList = [
{
"name": "张三",
"jobNumber": "1001",
"department": "技术部"
},
{
"name": "李四",
"jobNumber": "1002",
"department": "技术部"
}
];
2、导出
<input type="button" value="导出" @click="exportExcel" />
exportExcel() { //兼容ie10哦! require.ensure([], () => { const { export_json_to_excel } = require('../../vendor/Export2Excel'); //引入文件 const tHeader = ['姓名', '工号', '部门']; //将对应的属性名转换成中文 //const tHeader = []; const filterVal = ['name', 'jobNumber', 'department'];//table表格中对应的属性名 const list = exportData; //想要导出的数据 const data = this.formatJson(filterVal, list); export_json_to_excel(tHeader, data, '列表excel'); }) },
formatJson(filterVal, jsonData) { return jsonData.map(v => filterVal.map(j => v[j])); }
这里的exportData就是你想要导出的数组
exportData = [
{
"name": "张三",
"jobNumber": "1001",
"department": "技术部"
},
{
"name": "李四",
"jobNumber": "1002",
"department": "技术部"
}
];
