Django: How can I call a view function from template?

Question

I have a question on how to call a view function from a template HTML button? Like an onclick function? Here is the template:

<input id="submit" type="button" onclick="xxx" method="post" value="Click" />

And the views.py is:

def request_page(request):
    ...do something...
    return render_to_response("/directory.html", {})

Thank you very much.

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')
