vue导入excel文件，vue导入多个sheets
用input 导入 excel ，然后生成表格，然后调用接口上传到后台
html 导入按钮和选择文件的弹框
导入
js 重中之重 导入 excel 开始啦
1.data里面的数据
excelImportShow: false, //导入文件的弹框
uploadArr: [], // 上传给后台的数据
realname: '', // 以下都是我要转换的数据，因人而异
gender: '',
age: '',
minzu: '',
wenhua: '',
shengfenzheng: '',
job: '',
mobile: '',
mark: ''2. 导入弹框
daoru() {
this.excelImportShow = true
},3. 导入方法
// 导入
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]]); //outdata就是你想要的东西
this.da = [...outdata]
let arr = []
let nameArr = outdata[1]
for (let v in nameArr) {
// 拿到 excel 里面的列名，根据列名得到里面的键名
let title = nameArr[v]
switch (title){
case '姓名':
console.log('这是姓名',nameArr[v]);
_this.realname = v
console.log('这是realname',v);
break;
case '性别':
console.log('这是性别',nameArr[v]);
_this.gender = v
console.log('这是gender',v);
break;
case '年龄':
console.log('这是年龄',nameArr[v]);
_this.age = v
console.log('这是age',v);
break;
case '民族':
console.log('这是民族',nameArr[v]);
_this.minzu = v
console.log('这是minzu',v);
break;
case '学历':
console.log('这是性别',nameArr[v]);
_this.wenhua = v
console.log('这是job',v);
break;
case '身份证号':
console.log('这是身份证号',nameArr[v]);
_this.shengfenzheng = v
console.log('这是shenfengzheng',v);
break;
case '工作单位/学校/社区':
console.log('"工作单位/学校/社区"',nameArr[v]);
_this.job = v
console.log('这是job',v);
break;
case '手机/电话':
console.log('这是手机/电话',nameArr[v]);
_this.mobile = v
console.log('这是mobile',v);
break;
case '备注':
console.log('这是备注',nameArr[v]);
_this.mark = v
console.log('这是mark',v);
break;
default:
break;
}
}
let obj
let uploadArr = []
// 这里是一个excel里面会有多个sheets，把里面的恶数据整个到这个数组里面一起上传
let leng = Object.keys(wb.Sheets).length
// 用for循环，leng 是sheets的个数，用来循环次数
for (var i = 0; i < leng+1; i++) {
XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[i]])
let arrr = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[i]])
arrr = arrr.slice(2) //如果从第三行开始是数据，那这里就是1，如果从第四行开始是数据，那这里就是2
uploadArr.push.apply(uploadArr,arrr)
_this.uploadArr = uploadArr
}
this.da.map(v => {
let obj = {}
obj.id = v.id
obj.status = v.status
arr.push(obj)
})
let para = {
withList: arr
}
_this.$message({
message: '请耐心等待导入成功',
type: 'success'
});
}
reader.readAsArrayBuffer(f);
}
if (rABS) {
reader.readAsArrayBuffer(f);
} else {
reader.readAsBinaryString(f);
}
},4.确认导入 （其实这里就是上传到后台接口的，存到数据库里面才能保存）
// 确认导入
submit() {
let uploadArr = this.uploadArr
this.excelImportShow = false
let obj
for (let v in uploadArr) {
obj = {realname:uploadArr[v][""+this.realname+""],
age:uploadArr[v][""+this.age+""],
gender: uploadArr[v][""+this.gender+""]=='男'?'MALE':'FEMALE',
minzu: uploadArr[v][""+this.minzu+""],
wenhua: uploadArr[v][""+this.wenhua+""],
shengfenzheng: uploadArr[v][""+this.shengfenzheng+""],
job: uploadArr[v][""+this.job+""],
wenhua: uploadArr[v][""+this.wenhua+""],
mobile:uploadArr[v][""+this.mobile+""],
mark:uploadArr[v][""+this.mark+""],
place: "00"}
// 这里的obj 就是后台需要的参数，用变量表示键名 [""+此处是你的变量+""]
createUser(obj).then((res) => {
这是后台添加的方法
if (res.data.return_code === '200') {
this.dialogFormVisible = false
} else {
this.$notify.error(res.data.return_msg)
}
})
if (parseInt(v) === parseInt(uploadArr.length)-1) {
console.log(v+'和'+uploadArr.length);
setTimeout(()=>{
this.$notify({
title: '成功',
message: '创建成功',
type: 'success',
duration: 2000
})
this.getList({ page: 1,limit: 20 })
// 添加成功之后调用list 接口，展示所添加的数据
},1500)
}
}
},才疏学浅，若有不足欢迎补充
