Get the click event from a button in a django view

Question

i think the title is pretty clear. I want to know when the user clicks the button to run a piece of code in a function in my views.py. lets say i have this html:

You should create this function in your views.py, map it to the url in your urls.py and add event handler using JavaScript (pure JS or using jQuery as shown below):

JS (using jQuery):

$('#buttonId').click(function() {    
    $.ajax({
        url: your_url,
        method: 'POST', // or another (GET), whatever you need
        data: {
            name: value, // data you need to pass to your function
            click: true
        }
        success: function (data) {        
            // success callback
            // you can process data returned by function from views.py
        }
    });
});

HTML:

<div>
    <input type="button" id="buttonId" name="_mail" value="Enviar Mail">  
</div>

Python:

def verFactura(request, id_factura):

    ...    

    if request.POST.get('click', False): # check if called by click
        # send mail etc.        

    ...

Note that if you're going to use POST method you should care about csrf (cross-site request forgery) protection as described HERE
