Answer 1

You need to use the clearInterval function

    var interval = setInterval()....
    clearInterval(interval);

Answer 2

var interval = setInterval(function() {
    $.ajax({
        url: "test.php",
        success: function(result) {
            $("#results").append(result);
        }
    });
}, 1000);

clearInterval(interval);
