0















I want to get .csv file from user and show as a table. And I need to do pagination for that table. I used for that react-pagination-table. First I get from .csv file from react-file-reader. I did but showing error.
Here is my Code:



import React, { Component } from 'react';

import axios from 'axios';

import ReactFileReader from 'react-file-reader';

import { TablePagination } from 'react-pagination-table';



const sampleData = ``;

var result = ;

var data;

const Header = ["Name", "Department", "Designation", "Salary", "Joining Date" 

];



class Main extends Component {



constructor(props) {

super(props);

this.state={

  //csvData: null

  data: 

  };

 }



 handleFiles = files => {

var reader = new FileReader();

reader.onload = function(e) {

  var csv = reader.result;

  var lines = csv.split("n");

  console.log(lines.length);

  var headers=lines[0].split(",");

  for(var i=1;i<lines.length;i++){

    var obj = {};

    var currentline=lines[i].split(",");

    for(var j=0;j<headers.length;j++){

      obj[headers[j]] = currentline[j];

    }

    result.push(obj);

  }  

  //return result; //JavaScript object

  result = JSON.stringify(result); //JSON

  console.log(result);

  // Use reader.result

  this.setState({

      //csvData: reader.result

      data: result

  })

  }.bind(this);

reader.readAsText(files[0]);

 }



 render() {

  return(

    <div className="Main">

      <h1>Upload Your CSV File</h1>

        <div>

          <ReactFileReader 

            multipleFiles={false}

            fileTypes={[".csv"]} 

            handleFiles={this.handleFiles}>

            <button className='btn'>Upload</button>

          </ReactFileReader>

          <TablePagination

        title="TablePagination"

        subTitle="Sub Title"

        headers={ Header }

        data={ data }

        columns="Name.Department.Designation.Salary.Joining Date"

        perPageItemCount={ 5 }

        totalCount={ data.length }

        arrayOption={ [["size", 'all', ' ']] }

    />

        </div>

  </div>

  );

 }



 }



 export default Main;
