60秒倒计时

 var wait = 60;
            function time(o) {
                if (wait == 0) {
                    o.removeAttribute("disabled");
                    o.value = "获取验证码";
                    wait = 60;
                } else {
                    o.setAttribute("disabled", true);
                    o.value = "重新发送(" + wait + ")";
                    wait--;
                    setTimeout(function() {
                            time(o);
                        },
                        1000);
                }
