response to ajax (jquery) with variables

[Antonio Russoniello]

Hello,

i hope you can help me with this, I'm trying to send to an ajax (jquery from my html template) a response but i would like to send also a new variable.

in my html template I have:

    $("#init_date").click(function(){
        var some_date = {'init_date': init_date, 'end_date': end_date};
        $.post("/filter_dates/", some_date, function(response){
            if(response === 'success'){
                MAKE SOMETHING!!!
            else{ alert('error'); }
        });
    });

my django view look like:

def filter_date(request):
    if request.method == 'POST':
        example = ['A','B','C']
        init_date = request.POST['init_date']
        end_date = request.POST['end_date']
         MAKE SOMETHING!!
        return HttpResponse('success') AND HERE I WOULD LIKE TO SEND THE example ARRAY...
    else:
        return HttpResponse('error')

How can I send the array o some other variable as response?

Regards,
AR

Hi Antonio,

import simplejson as json

return HttpResponse(

    json.dumps({

        'array': example

    }),

    content_type="application/json"

)

That would do the trick. This is returned as JSON. Remember to set the content_type, otherwise the client can get confused.

Regards,

Andréas

Now I can read data from  ajax to my def but I have not idea to how send, for examle, an array to jquery and manage this from javascript...

I tried:

def json_prueba(request):
    arrg = [1,2,3,4]
    if request.method == 'POST':
        return HttpResponse(simplejson.dumps({'array': arrg}), content_type="application/json")
    return HttpResponse('FAIL!!!!!')

from the page side:

    function updateDB(){
        $.post("/sitioweb/json/", data, function(response){
            if(response){
                var data = JSON.parse(response); <--------- NOT SURE IF THIS IS CORRECT
                alert(data[0]); }              <----- I´m trying to put on an alert windows the first item of my array arrg
            else{ alert('Error! :(');}
        });
    }

Thanks in advande.

Hi again Antonio,

First of all, make sure you are using a good browser with debugging capabilities (I prefer Chrome), because you'll need it.

Secondly, I usually use the $.ajax request, instead of the post. Mainly because post is a wrapper around ajax and you can more finely change the settings of ajax.

So the post in your case would be:

$.ajax({

    type: 'POST',               // Make sure you post

    dataType: 'json',          // Use this so that you request json from the server

    url: "/sitioweb/json/",

    data: data,

    success: function(data) {

        // The data that is returned is your json data, already parser, so you don't have to parse it!

        alert(data.array[0]);     // Need to write "array" because that is what you are sending to the browser (your structure looks like that, check what the server is responding with)

    },

    error: function(xhr, textStatus, errorThrown) {

        console.log('AJAX communication failed:', textStatus, errorThrown);    // In case there is an error (for example a 500)

    }

});

Regards,

Andréas
