js：

$(function() {
    var $btn = $('.playbtn');
    var $btn02 = $('.g-lottery-img');
    var $tan=$('#info');
    var playnum = 1; //初始次数，由后台传入
    $('.playnum').html(playnum);
    var isture = 0;
    var clickfunc = function() {
        var data = [1, 2, 3, 4, 5];
        //data为随机出来的结果，根据概率后的结果
        data = data[Math.floor(Math.random() * data.length)];
        switch(data) {
            case 1:
                rotateFunc(1, 36, '01');
                break;
            case 2:
                rotateFunc(2, 108, '02');
                break;
            case 3:
                rotateFunc(3, 180, '03');
                break;
            case 4:
                rotateFunc(4, 252, '04');
                break;

                break;

        }
    }
    if(playnum>0)
    {
        $('.playbtn').addClass("playbtn02");

    }

    $btn.click(function() {
        if(isture) return; // 如果在执行就退出
        isture = true; // 标志为 在执行
        //先判断是否登录,未登录则执行下面的函数
        if(1 == 2) {
            $('.playnum').html('0');
            alert("请先登录");
            isture = false;
        } else { //登录了就执行下面
            if(playnum <= 0) { //当抽奖次数为0的时候执行
                alert("没有次数了");

                $('.playnum').html(0);
                isture = false;
            } else { //还有次数就执行

                playnum = playnum - 1; //执行转盘了则次数减1
                if(playnum <= 0) {
                    playnum = 0;
                }
                $('.playnum').html(playnum);
                clickfunc();
            }
        }
    });
    var rotateFunc = function(awards, angle, text) {
        isture = true;
        $btn.stopRotate();
        $btn02.rotate({
            angle: 0,
            duration: 4000, //旋转时间
            animateTo: angle + 1440, //让它根据得出来的结果加上1440度旋转
            callback: function() {
                isture = false; // 标志为 执行完毕
                $('#info'+text).show();
                if(playnum <= 0) { //当抽奖次数为0的时候执行
                    $('.playbtn').removeClass("playbtn02");
                }

            }
        });
