使用Ajax获取已发布的json数据的值

Question

When I make an ajax call, I get the ID of my input and I add the id to my json data.

I need to get this id to use it id my success function.

IE : In data id = 1, i need in success to get .qte1

If you have any idea... :)

$('#action-button').click(function() {
    $.ajax({
        type: 'POST',
        url: 'get_qty.php',
        data: {
            'id': $('input[name=qte]').val(),
        },
        success: function(data) {
            $(".qte").html("");
            $(".qte").append(data);

        }
    });
    return false;
});

If I understood you correctly you can just concat the value as such

var data = JSON.parse(data);
var $div = "#qte" + data.id;
$($div).html("test");

I have converted to json object because if you don't have access to the php file this at least converts from string to object. Make sure you are using a #to call a specific div not a class.

This is my PHP:

header('Content-type: application/json');
$arr = array("id"=> $_POST['id'],"qty"=> "1");
echo json_encode($arr);
