手机端转盘抽奖代码分享

演示效果如下:

不废话了,直接给大家贴代码了。

html部分

<div class="turntableWap top10">

<table border="0" cellspacing="0">

<tr>

<td tag="0"><img src="../images/4.png" alt="4元"></td>

<td tag="1" class="even"><img src="../images/6.png" alt="6元"></td>

<td tag="2"><img src="../images/8.png" alt="8元"></td>

<td tag="3" class="even"><img src="../images/11.png" alt="11元"></td>

</tr>

<tr>

<td tag="13" class="even"><img src="../images/13.png" alt="13元"></td>

<td colspan="2" rowspan="3" class="zpBtn"><img src="../images/zpBtn.jpg" /></td>

<td tag="4"><img src="../images/40.png" alt="40元"></td>

</tr>

<tr>

<td tag="12"><img src="../images/80.png" alt="80元"></td>

<td tag="5" class="even"><img src="../images/125.png" alt="125元"></td>

</tr>

<tr>

<td tag="11" class="even"><img src="../images/250.png" alt="250元"></td>

<td tag="6"><img src="../images/400.png" alt="400元"></td>

</tr>

<tr>

<td tag="10"><img src="../images/1000.png" alt="1000元"></td>

<td tag="9" class="even"><img src="../images/iphone6.png" alt="iphone6"></td>

<td tag="8"><img src="../images/Thank2.png" alt="谢谢惠顾"></td>

<td tag="7" class="even"><img src="../images/500.png" alt="500元"></td>

</tr>

</table>

</div>

css部分,由于做的这个转盘是手机端的,采用的响应式布局

.turntableWap{ padding:1rem; background:url(../images/zpTabBg.jpg) no-repeat center; background-size:100% 100%;}

.turntableWap table{ width:100%;}

.turntableWap table td{ vertical-align:middle; text-align:center; background-color:#ecd295;}

.turntableWap table td img{ width:100%; }

.turntableWap table td.even{background-color:#f6e8c5}

.turntableWap table td.active{ background-color:#ed9351;}

js部分

$(".turntableWap .table").css({"height":$(".turntableWap .table").width()});//做响应式布局,外table是等宽高

var isdo = true;

$(".zpBtn").on("click",function(){

var num = 13;//后台传入的奖品

var rotaNum = 14;//奖品数量

var count = -1;//高亮显示,旋转特效

var jishi = 0;//计时时间段

var speed = 50;//快速速度

var speedSlow = 200;//慢速速度

choujiang()//抽奖方法调用,在此处做判断调用choujiang(),并给num值

function choujiang(){

if(isdo){

isdo=false;

$(".turntableWap").css({"background-image":"url(../images/1.gif)"})

var c = setInterval(function(){

if(count >12){

count = -1;

}

count = count+1;

jishi = jishi+1;

$(".turntableWap td").removeClass("active");

$(".turntableWap td[tag="+count+"]").addClass("active");

if(jishi>rotaNum*2){

clearInterval(c);

c = setInterval(function(){

count = count+1;

jishi = jishi+1;

$(".turntableWap td").removeClass("active");

$(".turntableWap td[tag="+count+"]").addClass("active");

if(jishi>num+rotaNum*2){

clearInterval(c);

$(".turntableWap").css({"background-image":"url(../images/zpTabBg.jpg)"})

isdo = true;

var jp = $(".turntableWap td[tag="+count+"]").find("img").attr("alt")

alert("恭喜您获取"+jp)

}

},speedSlow)

}

},speed)

}else{

return;

}

}

})
