Question

我像这样写了forms.py

# -*- coding: utf-8 -*-

from django import forms

class InputForm(forms.Form):
  name = forms.CharField(max_length=100)
  select1 = forms.ChoiceField(widget=forms.RadioSelect,required=False)
  select2 = forms.ChoiceField(widget=forms.RadioSelect,required=False)

以html

<div>
    {{ f.select1 }}
     <label　for="select1" dataGoTo="7">select１</label>
    {{ f.select2 }}
     <label for="select2">select２</label>
</div>

在views.py

中

def get_data(request):
    if request.method == "POST":
        form = InputForm(data=request.POST)
        if form.is_valid():
            name = form.cleaned_data['name']

我想获取选择了select1或select2的值。我应该如何写在views.py中？

您可以使用Ajax在Javascript中完成此操作。右键单击浏览器中的页面，然后选择“查看源代码”。找出您的表单是什么，然后选择元素的ID或类。然后在您的Javascript（jQuery）中执行以下操作：

"use strict";
$(document).ready(function() {
$('form#form_id').on('submit', function(){
  // your option elements must have a 'value' attribute
  var selectedValue = $('select#select_id').val();

  $.ajax({
    type:'POST',
    url:'your/view/url',
    data:{
        'selected': selectedValue,
    },
    dataType: 'json',
    success:function(data){
        // error handling
        if (data['status']==='ok') {
            // display success message
        } else {
            console.log(data);
        }
    }, // success
  }); //ajax
}); // on form submit
}); // document ready

然后在您的views.py：

from django.views.generic import View
from django.contrib.auth.mixins import LoginRequiredMixin
from django.http import JsonResponse


class SomeAjaxView(LoginRequiredMixin, View):
    def post(self, request, *args, **kwargs):
        if request.user.is_authenticated:
            selected = request.POST.get('selected', None)

            if selected:
                # do something here

                return JsonResponse({'status':'ok'})
            else:
                return JsonResponse({'status':'ko', 'error': 'Value missing'})

        return JsonResponse({'status':'ko', 'error': 'Not authenticated'})

使用Ajax的好处是不会在提交时刷新整个页面。这是当今行业标准的做法。
