python - Javascript to Django views.py? -

this may sound simple, how send data javascript array in index.html template views.py?

when user clicks "recommend" button, code calls function accesses database , prints name on template.

def index(request):     if(request.get.get('recommend')):         sql_handler.recfunc()         context['name'] = sql_handler.name         return render(request, 'polls/index.html', context) 

i have array of checkbox values in javascript calculated after user presses "recommend". want send index view , use parameter function.

so:

def index(request):     if(request.get.get('recommend')):         sql_handler.recommend()         context['name'] = sql_handler.name         //something??         tags = check_array_javascript         context['tags'] = tags         return render(request, 'polls/index.html', context) 

how can this? i've been searching similar questions, i'm new django , web development in general, either did not understand answers or didn't me.

alright, sending data client (javascript) backend (your django app) need employ called ajax, stands asynchronous javascript , xml. allowing communicate backend services without need of having reload page, which, have using normal post or put form submission.

the easiest implementation using jquery. jquery first , foremost dom manipulation library since inception has grown encompass more that.

a jquery ajax call looks this.

$(document).ready(function() {     $.ajax({         method: 'post',         url: '/path/to/your/view/',         data: {'yourjavascriptarraykey': yourjavascriptarray},         success: function (data) {              //this gets called when server returns ok response              alert("it worked!");         },         error: function (data) {              alert("it didnt work");         }     }); }); 

this can checked in views.py

def index(request):     if request.is_ajax():         #do         request_data = request.post         return httpresponse("ok")
