如何将值从Django模板传递到视图

<form method="post" action="{% url 'your_view_name' %}">
    {% csrf_token %}
    <input type="text" name="user_input" />
    <button type="submit">Submit</button>
</form>

from django.shortcuts import render
from django.http import HttpResponse

def your_view(request):
    if request.method == 'POST':
        user_input = request.POST.get('user_input')
        # 处理 user_input
        return HttpResponse(f'You entered: {user_input}')
    return render(request, 'template.html')

from django.urls import path
from . import views

urlpatterns = [
    path('your-path/<str:param>/', views.your_view, name='your_view_name'),
]

<a href="{% url 'your_view_name' param='some_value' %}">Link with parameter</a>

from django.shortcuts import render

def your_view(request, param):
    # 使用 param 变量
    return render(request, 'template.html', {'param': param})

<button id="submit-button">Submit Data</button>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function(){
    $('#submit-button').click(function(){
        $.ajax({
            url: '{% url "your_view_name" %}',
            method: 'POST',
            data: { user_input: 'some_value', csrfmiddlewaretoken: '{{ csrf_token }}' },
            success: function(response){
                alert('Data sent successfully');
            }
        });
    });
});
</script>

from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def your_view(request):
    if request.method == 'POST':
        user_input = request.POST.get('user_input')
        # 处理 user_input
        return JsonResponse({'status': 'success', 'data': user_input})
    return render(request, 'template.html')
