使用 AJAX 获取 HTML 元素的文本并将其传递给 django 视图

Question

I have the following paragraph: <p>{{donation.pk}}</p> .

I want to pass the value of the paragraph into the view bellow as a pk

def acceptdonation(request, pk): #the `pk` should be the `pk` of the `p` element
    deleteitem = Donation.objects.filter(id = pk) 
    deleteitem.delete()
    return redirect('/dashboard/') 

I did research, and heard that you need to use AJAX.

How exactly can I achieve this. I am not to good with javascript so the easiest and most minimalist way would be helpful.

PLEASE NOTE: I already have a button that calls the view, I just want to pass the value of the p element into my function

Answer 1

Assuming that the path of your view is something like:

path('acceptdonation-path/<int:pk>/', views.acceptdonation, name='acceptdonation-view'),

You can use the name of the path to get the URL in your template:

<a href="{% url 'acceptdonation-view' pk=donation.pk %}">click</a>

Then just simply custom the link to look like a button with CSS, or if you really want to use a button, you can do something like:

<form action="{% url 'acceptdonation-view' pk=donation.pk %}">
    <button type="submit" value="click" />
</form>

No AJAX request is needed here, just because, at the end of your request, there is a redirection that is not commonly used in AJAX requests, so a simple request should fit good here.
