Modal + form + values (bootstrap and javascript)

From the following link

http://getbootstrap.com/javascript/#live-demo

I created the following modal

https://github.com/rg3915/front_end/blob/master/javascript/modal_form.html

In the modal I fill a value and it will update this value in the form of the page (which will have more fields...)

Question: how do I do this using only Javascript, Jquery and Ajax?

<html>
<head>
    <meta charset="utf-8">

  <title>Modal</title>

  • I don’t understand very well what it will update. O input price? A database? A variable for calculations? What exactly?

Take a look at this example: http://jsfiddle.net/emirdeliz/bbqmm3dt/

In html:

 <!-- Button trigger modal -->
    <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
        Atualizar valores
    </button>

    <div class="container">
        <form class="form-horizontal col-sm-2" action="." method="POST">
            <div class="form-group">
                <label for="id_price">Preço</label>
                <input type="text" id="id_price" name="movie" class="form-control">
            </div>

            <div class="form-group">
                <div class="">
                    <button type="submit" id="id_submit" class="btn btn-primary">Salvar</button>
                </div>
            </div>
        </form>
    </div>


    <!-- Modal -->
    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title" id="myModalLabel">Atualizar valores</h4>
                </div>
                <div class="modal-body">
                    <input id="novoValor" type="text" placeholder="Digite o valor">
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Fechar</button>
                    <button id="btAtualizarValor" type="button" class="btn btn-primary" data-dismiss="modal">Atualizar</button>
                </div>
            </div>
        </div>
    </div>

No js:

$(function(){
    $("#btAtualizarValor").click(function(){
        $("#id_price").val($("#novoValor").val());
    });
});
