css用到了幾個運動處理了爪子的動效，如下方代碼所示

@keyframes run {
  0% {
    background-image: url(../images/dx-zhua3.png);
  }
  25% {
    background-image: url(../images/dx-zhua2.png);
  }
  50% {
    background-image: url(../images/dx-zhua1.png);
  }
  75% {
    background-image: url(../images/dx-zhua2.png);
  }
  100% {
    background-image: url(../images/dx-zhua3.png);
  }
}
@keyframes zhuashou {
  0% {
    top: 360px;
    background-image: url(../images/dx-zhua1.png);
  }
  100% {
    top: 360px;
    background-image: url(../images/dx-zhua2.png);
  }
}
@keyframes zhuadown {
  0% {
    top: 138px;
    background-image: url(../images/dx-zhua1.png);
  }
  100% {
    top: 360px;
    background-image: url(../images/dx-zhua1.png);
  }
}
@keyframes zhua-slideUp {
  0% {
    top: 360px;
    background-image: url(../images/dx-zhua2.png);
  }
  100% {
    top: 138px;
    background-image: url(../images/dx-zhua2.png);
  }
}
@keyframes img-slideUp {
  0% {
    top: 23px;
  }
  100% {
    top: -200px;
  }
}

js代碼創(chuàng)建了一個控制器類，處理事件以及動畫效果的交替等。

var Carousel = {
    data: {
    result: 1
},
init: function () {
    Carousel.control();
},
stop: function () {
    $(".zhua").removeClass("zhuamove").addClass("zhuadown");
    $(".zhua-zhu").addClass("zhudown");
    var timer01 = setTimeout(function () {
        $(".zhua").removeClass("zhuadown").addClass("zhuashou");
        var timer03 = setTimeout(function () {
            $(".zhua").removeClass("zhuashou").addClass("zhuaup");
            $(".zhua-zhu").removeClass("zhudown").addClass("zhuup");
            $(".poster-list .lw" + (Carousel.data.result + 1)).addClass("img-slideUp");
        clearTimeout(timer03);
        timer03 = null;
        }, 800);
        var timer02 = setTimeout(function () {
            $(".zhua").removeClass("zhuaup").removeClass("zhuaup1");
            $(".zhua-zhu").removeClass("zhuup");
            clearTimeout(timer02);
            timer02 = null;
            alert("恭喜您抽中一等獎~");
            Carousel.start();
        }, 2500);
        clearTimeout(timer01);
        timer01 = null;
    }, 1000);
},
start: function () {
    $(".zhua").addClass("zhuamove");
    $(".zhua").removeClass("zhuadown").removeClass("zhuaup1").removeClass("zhuaup");
    $(".poster-list .item").removeClass("img-slideUp").removeClass("img-slideOutUp");
},
zhuaMove: function (num) {
    switch (num) {
        case 0:
        $(".zhua-top").animate({
            left: -145,
        },300);
        break;
        case 1:
        $(".zhua-top").animate({
            left: 0,
        },300);
        break;
        case 2:
        $(".zhua-top").animate({
            left: 145,
        },300);
        break;
    }
},
control: function () {
    $("#left").on("click", function () {
        Carousel.data.result--;
    if (Carousel.data.result <= 0) {
        Carousel.data.result = 0;
    }
    Carousel.zhuaMove(Carousel.data.result);
    });
    $("#stop").click(Carousel.stop);  
        $("#right").on("click", function () {
            Carousel.data.result++;
            if (Carousel.data.result >= 2) {
                    Carousel.data.result = 2;
            }
            Carousel.zhuaMove(Carousel.data.result);
        });
    },
};
