在Flask-WTF中填写表单并选择默认值

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField

class MyForm(FlaskForm):
    name = StringField('Name', default='John Doe')
    email = StringField('Email', default='john@example.com')
    submit = SubmitField('Submit')

from flask import Flask, render_template

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'

@app.route('/', methods=['GET', 'POST'])
def index():
    form = MyForm()
    if form.validate_on_submit():
        # 处理表单提交的数据
        name = form.name.data
        email = form.email.data
        # 其他逻辑处理
        return 'Form submitted successfully!'
    return render_template('index.html', form=form)

if __name__ == '__main__':
    app.run()

<form method="POST" action="/">
    {{ form.csrf_token }}
    {{ form.name.label }}: {{ form.name }}
    {{ form.email.label }}: {{ form.email }}
    {{ form.submit }}
</form>
