Question

I have the following ajax call

function update_ledger_amount(id) {
    $.ajax({
        type: "POST",
        url: "/ledgeritems/UpdateAmount",
        data: "Id=" + id + "&Amount=" + $('#ledger_edit_amount_input_' + id).val(),
        success: function (str) {
            var result = str.split('|');
            alert(str);
            if (result[0] == 'success') {
                set_display_message('Item updated', 'success');
                load_ledger_month($('#BankAccountId').val(), $('#StartDate').val());
            }
            else {
                alert('bad');
                set_display_message(result[1], 'error');
            }
        },
        error: function (request, status, error) {
            alert(error);
        }
    });
}

The problem I’m having is that I get no alerts on success or error. Watching the traffic via firebug I can see the response is a simple

success

I believe the problem could have to do with the content-type of the response, it shows as text/javascript. I’m thinking maybe I need to do something different to handle that content type.

Answer 1

use dataType as json and send the response as json in your controller(php).. you can do that by …echo json_encode(array('success'=>'success'))

JQUERY

$.ajax({
    type: "POST",
    url: "/ledgeritems/UpdateAmount",
    data: "Id=" + id + "&Amount=" + $('#ledger_edit_amount_input_' + id).val(),
    dataType:'json',
    success: function (str) {
        alert(str.success);  //in mycase.. you can do your stuff here
        /*var result = str.split('|');
        alert(str);
        if (result[0] == 'success') {
            set_display_message('Item updated', 'success');
            load_ledger_month($('#BankAccountId').val(), $('#StartDate').val());
        }
        else {
            alert('bad');
            set_display_message(result[1], 'error');
        }*/
    },
    error: function (request, status, error) {
        alert(error);
    }
});

PHP

.....
echo json_encode(array('success'=>'success'));

this sends success as json and you can get that in success function of ajax
