Question

如何获取输入值？我用HTML编写了代码，

<form action="{% url 'app:top' %}" method="POST">
              <input type="radio" name="no" value="1">
              <label>No</label>
              <input type="radio" name="yes" value="1">
              <label>Yes</label>
<input class="disabled" type="submit" value="POST">
</form>

在views.py中；

def top(request):
    no = request.POST.get("no","0")
    yes = request.POST.get("yes","0")

    print(no)
    print(yes)

当我没有标签并放置发送按钮时，将打印0。放置是按钮是相同的。为什么会发生？为什么我不能打印出1？我该怎么办？
