python - Flask Python 按钮没有响应

Question

我有一个页面/contact.html。它有一个按钮，提交后会将我带到用户登录的第二页(algo.html)。在第二页上，我有两个按钮，但我无法响应。这是我的代码:

@app.route('/contact', methods = ['GET', 'POST'])
def contact():
    form = ContactForm()

    if request.method == 'POST':
        return render_template('algo.html')
    if request.method == 'POST' and request.form['submit'] == 'swipeleft':
        print "yes"

在 contact.html 上我有:

<form action="{{ url_for('contact') }}" method=post> 
{{ form.hidden_tag() }}
{{ form.name.label }}
{{ form.name }}
{{ form.submit }}

在 algo.html 上我有:

<input type = "submit" name = "submit" value = "swipeleft" method=post>
<input type = "submit" name = "submit" value = "swiperight" method=post>

Answer 1

在您的 algo.html 模板中，您需要将表单提交回同一网址 /contact，因为这是您检查 值的地方向左滑动:

<form action="{{ url_for('contact') }}" method="post">
   <input type = "submit" name = "submit" value = "swipeleft" />
   <input type = "submit" name = "submit" value = "swiperight" />
</form>
