Flask Form Submit 什么都不做

Question

点击提交按钮实际上什么也没做。提交空白表单将触发对必填字段的验证，但按要求填写表单会导致表单不提交/提交按钮什么也不做。模板有CSRF_Token，提交按钮在form标签中，form标签有指向正确方向的action属性。 Chrome 不会出现任何错误，所以我不知道如何继续。

你写的东西看起来很复杂，为什么不尝试一些简单的东西呢-

@app.route("/connect",methods=['GET','POST'])
def connect():
    if request.method=='GET':
        return render_template('connect.html')
    if request.method=="POST":
        return render_template('Thankyou.html',name=request.form['name])

在你的 views.py 和你的 connect.html 表单中只写-

<form name="connect" method="post" action="{{ url_for('connect') }}">
        <input class="t1" type="text" id="email" name="email" placeholder="Your Email ID">
        <input class="t2" type="text"  id="name" name="name" placeholder="name">
        <button class="btn btn-primary but" type="submit">Send</button>
    </form>

最后一页，Thankyou.html可以是这个样子-

<p>Thanks for contacting me, {{ name }} </p>
