Question

我有一个程序，我在其中读取CSV文件并验证多个CSV文件标题列，其中列标题计数应相同，而列标题名称应相同（如果不匹配，则显示一些错误消息）< / p>

我已经在python中完成了验证，但是我不知道如何在javascript / jquery中进行验证。我想从HTML文件

进行操作

用于验证的Python程序：

from flask import Flask, render_template
import os
import csv
import pandas as pd
import numpy as np
app = Flask(__name__)

APP_ROOT = os.path.dirname(os.path.abspath(__file__))
@app.route("/")
def index():
    print("Loading the root file")
    return render_template("upload.html")
@app.route("/upload", methods=['POST'])
def upload():
    target = os.path.join(APP_ROOT, 'input/')
        print("target-",target)

        if not os.path.isdir(target):
            os.mkdir(target)

abs_path_files=[]
    for file in request.files.getlist("source_fileName"):
            print("file-",file)
            filename = file.filename
            print("filename-",filename)
            destination = "/".join([target, filename])
            print("destination-",destination)
            file.save(destination)
            print("file>",file)
            tempFile = os.path.abspath(destination)
            abs_path_files.append(tempFile)
            print("abs_path_files - " ,abs_path_files)
            global files_list
            files_list=abs_path_files
            print("files_list-",files_list)
    return redirect('/compute',)

@app.route("/compute")# Here we are performing the Header columns Validation 
def compute():
    dataFrames=[]
    for f in files_list:
        dataFrame=pd.read_csv(f)
        dataFrames.append(dataFrame)
    col_in_files = set([",".join(list(f.column.values)) for f in dataFrames])
    if len(col_in_files)==1:
       # After validation it will go for the other computations

HTML：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title> upload </title>
</head>
<body>
<div class="container">
    <h1>Large Data Generation</h1> 
<form id = "upload-form" action="{{ url_for('upload') }}" method="POST" enctype="multipart/form-data">
        <div id="file-selector">
            <p> 
                <strong>Source File: </strong>
                <input id="source_fileName" type="file" name="source_fileName" accept="csv/*" multiple />
            </p> 
        </div>
    <input type="submit" value="Generate Data" id="upload-button"  >
</form>
</div>
</body>
