Answer 1

setInterval("CountDown()", 1000);是延时1秒执行CountDown方法，所以你需要这之前先调用CountDown一次

Answer 2

if (event.keyCode == 32) {
                    if ($("#timertag").val() == 0) {
                        clearInterval(timer);
                        $("#timertag").val("1");
                        maxtime = parseInt($("#timerhidden").val());
                        CountDown();
                        timer = setInterval("CountDown()", 1000);
                    } else {
                        clearInterval(timer);
                        $("#timerhidden").val(maxtime)
                        $("#timertag").val("0");
                    }
                }
