问题描述
我有一个可以用于机票预订的程序，如果用户预订将其价值存储到变量 booking 的三张机票，我想根据该变量 booking的值进行循环表单输入.
像这样的表格，如果我预订三个股票，该表格也会显示三个输入表格.
I have a program that can use for ticket booking, if user booking three ticket it value stored to variable booking, i want to make looping form input based on value from that variable booking .
like this form, if i booking three ticker, the form also display three input form.
这是我的 app.py :
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def index():
booking = 3
return render_template('index.html')
if __name__ == "__main__":
app.run(host='0.0.0.0', debug=True)
index.html
<body>
<form action="">
{% for contact in booking %}
Name: <br>
<input type="text" value="{{ contact }}"><br>
Age: <br>
<input type="text" value="{{ contact }}">
{% endfor %}
</form>
</body>
那么..该怎么做..?
so.. how to do that..?
推荐答案
我测试了以下内容，这应该可以工作.将返回的渲染模板重写为此:
I tested the following, this should work. Rewrite your return render template to this:
return render_template('index.html', booking = booking)
并按如下所示重写您的html:
And rewrite your html as follows:
<body>
<form action="">
{% for i in range(booking) %}
Name: <br>
<input type="text" value="{{ contact }}"><br>
Age: <br>
<input type="text" value="{{ contact }}">
{% endfor%}
</form>
</body>
您确定要为姓名和年龄设置相同的值吗?
are you sure you want the same value for name and age btw?
