九方格抽奖插件

自己编写的九方格抽奖插件

参考网址http://demo.qpdiy.com/all/plugins/Lottery/lottery--horse3/h/index.html

关键代码：

var num = 0; //当前点亮的灯
  var circle = 0; //至少转跑马灯的圈数
  var t; //定时器
  var len;//奖品个数
  function lightChange($prizes, changeClass, prizeArr, prizeNum){
      var self = this;
      len = $prizes.length;

      $prizes.removeClass(changeClass);
      $prizes.eq(prizeArr[num]).addClass(changeClass);
      if(num == len-1){
        num = 0;
        circle ++;
      } else {
        num ++;
      }

      if(circle == 2 && num == prizeNum){
        circle = 0;
        clearTimeout(t);
      } else {
        t = setTimeout(function(){lightChange($prizes, changeClass, prizeArr, prizeNum)},300); 
      }
    }
