One option is, you can wrap the submit button with a form

Something like this:

<form action="{% url path.to.request_page %}" method="POST">
    <input id="submit" type="button" value="Click" />
</form>

(remove the onclick and method)

If you want to load a specific part of the page, without page reload – you can do

<input id="submit" type="button" value="Click" data_url/>

and on a submit listener

$(function(){
     $('form').on('submit', function(e){
         e.preventDefault();
         $.ajax({
             url: $(this).attr('action'),
             method: $(this).attr('method'),
             success: function(data){ $('#target').html(data) }
         });
     });
});

Assuming that you want to get a value from the user input in html textbox whenever the user clicks ‘Click’ button, and then call a python function (mypythonfunction) that you wrote inside mypythoncode.py. Note that “btn” class is defined in a css file.

inside templateHTML.html:

<form action="#" method="get">
 <input type="text" value="8" name="mytextbox" size="1"/>
 <input type="submit" class="btn" value="Click" name="mybtn">
</form>

inside view.py:

import mypythoncode

def request_page(request):
  if(request.GET.get('mybtn')):
    mypythoncode.mypythonfunction( int(request.GET.get('mytextbox')) )
return render(request,'myApp/templateHTML.html')

How about this:

<a class="btn btn-primary" href="{% url 'url-name'%}">Button-Text</a>

The class is including bootstrap styles for primary button.

you can put the input inside a form like this:-

<script>
    $(document).ready(function(){
        $(document).on('click','#send', function(){
            $('#hid').val(data)
            document.forms["myForm"].submit();
        })
    })
</script>

<form id="myForm" action="/request_page url/" method="post">
    <input type="hidden" id="hid" name="hid"/>
</form>
<div id="send">Send Data</div>

For deleting all data:

HTML FILE

  class="btn btn-primary" href="{% url 'delete_product'%}">Delete

Put the above code in an anchor tag. (the a tag!)

url.py

path('delete_product', views.delete_product, name='delete_product')]

views.py

def delete_product(request):
    if request.method == "GET":
        dest = Racket.objects.all()
        dest.delete()
        return render(request, "admin_page.html")

For example, a logout button can be written like this:

<button class="btn btn-primary" onclick="location.href={% url 'logout'%}">Logout</button>

Where logout endpoint:

#urls.py:
url(r'^logout/$', auth_views.logout, {'next_page': '/'}, name='logout'),
