Read data from dynamically generated forms with Javascript

Question

so ive an HTML page that have multiple generated forms:

{% for row in data %}
    <form action="/aggiorna_pratica" method='POST' id="inserisci_app_{{ row[0][1] }}">
       <input name="id_pratica_{{ row[0][1] }}" type='hidden 'id="id_pratica_{{ row[0][1] }}" value="{{ row[0][1] }}"></input> 

       <button type="submit" class="btn btn-success aggiorna_app">
          <i class="fa fa-check"></i>
       </button>
    </form>
{% endfor %}

row[0][1] contains the id of the row.

Im trying to send ajax requests from every single one of them, but i get the same ID of the frist row from every row.

This is the Javascript

$(document).ready(function() { $(".aggiorna_app").click(function(event) { 
//prevent submit
event.preventDefault(); //Thx @alex

//do things on submit
$.ajax({
    data : {
        tipo_richiesta : "inserisci_intervento",
        id : $('#id_pratica').val(),
        data_int : $('#data_int').val(),
        ora_int : $('#ora_int').val()
    },
    type: "POST",
    url: "/aggiorna_pratica",
    beforeSend: function(){
        //Before send data
    },
    success: function(data){
        console.log(data);
    }
});

}); });

I know im a newbie but i could really use some help

Here is a working example to test your click event. The click event is on .aggoriorna_app buttons inside each form, but the id being passed into the ajax call looks to be grabbing the .val() every time, eg, $('#id_pratica').val() . You'll see in my example that when a button is clicked, find the nearest input value and set the ajax id to that value. I assume that's what you need.

 $(document).ready(function() { $(".aggiorna_app").click(function(event) { //prevent submit event.preventDefault(); //Thx @alex var id = $(this).parent().find('input').val(); alert(id); }); });

 form { margin-bottom: 3rem; }
