插件描述:很实用的大转盘插件,配置简单易用,各种回调,方便快捷
<div id="box" class="box">
<div class="outer KinerLottery KinerLotteryContent"><img src="./imgs/lotteryContent.png"></div>
<!-- 大专盘分为三种状态:活动未开始(no-start)、活动进行中(start)、活动结束(completed),可通过切换class进行切换状态,js会根据这3个class进行匹配状态 -->
<div class="inner KinerLotteryBtn start"></div>
</div>
js部分
/**
* 根据转盘旋转角度判断获得什么奖品
* @param deg
* @returns {*}
*/
var whichAward = function(deg) {
if ((deg > 330 && deg <= 360) || (deg > 0 && deg <= 30)) { //10M流量
return "三网通流量 10M";
} else if ((deg > 30 && deg <= 90)) { //IPhone 7
return "iPhone7";
} else if (deg > 90 && deg <= 150) { //30M流量
return "三网通流量 30M";
} else if (deg > 150 && deg <= 210) { //5元话费
return "话费5元";
} else if (deg > 210 && deg <= 270) { //IPad mini 4
return "ipad mini4";
} else if (deg > 270 && deg <= 330) { //20元话费
return "话费20元";
}
}
var KinerLottery = new KinerLottery({
rotateNum: 8,
//转盘转动圈数
body: "#box",
//大转盘整体的选择符或zepto对象
direction: 0,
//0为顺时针转动,1为逆时针转动
disabledHandler: function(key) {
switch (key) {
case "noStart":
alert("活动尚未开始");
break;
case "completed":
alert("活动已结束");
break;
}
},
//禁止抽奖时回调
clickCallback: function() {
//此处访问接口获取奖品
function random() {
return Math.floor(Math.random() * 360);
}
this.goKinerLottery(random());
},
//点击抽奖按钮,再次回调中实现访问后台获取抽奖结果,拿到抽奖结果后显示抽奖画面
KinerLotteryHandler: function(deg) {
alert("恭喜您获得:" + whichAward(deg));
} //抽奖结束回调
});
