How to show input (name + value) in textarea?

I'm working on this project where I need to have the value of a textarea change when one of the input values in the same form changes.

HTML:

<form id="form" action="" method="">
<textarea readonly class="overview"></textarea>
<input type="text" class="add" name="product1" />
<input type="text" class="add" name="product2" />
<input type="text" class="add" name="product3" />
<input type="text" class="add" name="product4" />
</form>

The customer is allowed to change the input.class. The textarea-value should change whenever one of the inputs changes.

The textarea should show something like:
3 x product1
1 x product3
4 x product4

Anybody got an idea?

Thanks in advance,

Joel

var fd = new FormData()
fd.append('csrfmiddlewaretoken', document.getElementsByName('csrfmiddlewaretoken')[0].value)
fd.append('field_name', $("input[name='field_name']").serialize())

will return

['field_name=9&field_name=15&field_name=10']

you will then have to parse the info in your view

$('input').keyup(function () {
    var inputedValue = $(this).val();
    var name = $(this).attr('name');
    $(".overview").text(inputedValue+name);
});

  $(".add").keyup(function () {
 var app=""
 $(".add").each(function () {
       if( $(this).val() ) {
     var value=$(this).val();
     var name=$(this).attr('name');
     app +=value+"*"+name+ "\n" ;     
       }
 });
  $(".overview").text(app);

});

Watch this.

Hope this will give you some solution.

This will do what you want...

$("input.add").keyup(function() {
    var msg = "";
    $("input.add").each( function() {
        if( $(this).val() ) {
            msg += $(this).val() + "x " + $(this).attr("name") + "\n";
        }
    });
    $("textarea.overview").text(msg)
});

I used this with your HTML here: http://jsfiddle.net/XYXpp/

<textarea readonly class="overview" id="mytxtarea"></textarea>
   $("#product1").blur(function(){
   if($("#product1").val()!='')
     {
      $("#mytxtarea").val('test value');
     }
});
