引入抽奖插件lottery.js

<script type="text/javascript" src="js/lottery.js"></script>

开始抽奖函数start_lottery()

function start_lottery(){ 
    if(flag){ 
        //alert('正在抽奖,请等待抽奖结果!'); 
        //return false; 
        return void(0); 
    } 
    flag=true; 
    index = 1;              //当前选中对象的位置 
    fast  = rand(3,6);      //在哪个位置开始加速 
    cycle = rand(3,5);      //转动多少圈 
    speed = 300;            //开始时速度 

    $.ajax({ 
        url: 'lottery.php', 
        type: "post", 
        data:null, 
        dataType: "json", 
        timeout: 20000, 
        cache: false, 
        beforeSend: function(){// 提交之前 
        }, 
        error: function(){//出错 
            flag=false; 
        }, 
        success: function(res){//成功 
            if(typeof(res.award_id)!='undefined'){ 
                lucky = res.award_id;    //中奖号码 
                award = res.award_name;  //奖品名称 
                show_lottery(); 
            }else{ 
                flag=false; 
                alert(res.err); 
            } 
        } 
    }); 
}

PHP里奖品配置

//奖品配置 $award = array( 
    // 奖品ID => array('奖品名称',概率) 
    1 => array('悟空公仔',0.1), 
    2 => array('小乖虎公仔',0.1), 
    3 => array('神秘大礼包',0.1), 
    4 => array('智能游戏手柄',0.1), 
    5 => array('小角鹿公仔',0.1), 
    6 => array('豆蛙抱枕',0.1), 
    7 => array('游戏耳机',0.2), 
    8 => array('雷蛇键盘',0.2), 
); 

$r =rand(1,100);
