私はPythonとAJAXの初心者です。なぜapp.htmlでapp.pyを実行すると、表示したい結果がフォーム全体に置き換えられますか？ここでフォームを正しくAJAXでFlaskに送信するには？
私のコードです：
from flask import Flask, render_template, request
app = Flask(__name__,
template_folder='C:\\Users\\iyzadsyammil\\PycharmProjects\\PVT - Copy')
@app.route('/App',methods=['GET', 'POST'])
def showapp():
error = " "
finalpb= 0
x=0
logpb=0
if request.method == 'POST':
ingor = request.form['inGOR']
ingor = float(ingor)
try:
finalpb = ingor
except ValueError:
error = "Please enter an appropriate value!"
return render_template('app.html',error=error,finalpb=finalpb)
if __name__ == "__main__":
app.run(debug=True)
これは私のPythonのフラスコファイルです

これは私のhtml
である私のAJAXの一部でのみ
私はすでに両方のコードブロックを見ました、申し訳ありません！ ;） –
コマンドラインでcurlを使って 'http：// yourdomain/App'にアクセスするとどうなりますか？あなたのアプリの外に投稿をして、AJAX opが何をしているのかをエミュレートしてみてください。 – halfer
どこですか？私は理解していません – iyzad
