幸运⼤转盘抽奖抽奖算法程序实现逻辑近期碰到的⼀个需求，实现⼀个类似⼤转盘抽奖的功能，需⾃定义奖项，各奖项中奖概率，当⽇抽奖最⼤次数，抽奖成本等。

分享⼀个简单的java代码的实现的思路，有不⾜之处感谢各位指正。

初步⽅法⾸先要定义⼏个奖品，例如：iphone 中奖机率 10%100元购物卷中奖机率 30%10元购物卷中奖机率 50%总的中奖机率是 10%+30%+50%=90%剩余10%是谢谢惠顾，不中奖的设计思路这个是把所有商品按照概率分配到数组⾥⾯A[0] = iphoneA[1] = iphoneA[2] = iphone...A[10] = iphoneA[11] = 100元购物卷A[12] = 100元购物卷...然后随机⼀个0到99的数字，例如现在随机的数字是2那么A[2]就是中奖的商品A[2] = iphone//定义中奖率分母百分之int probabilityCount = 100;String[] prizesId = new String[probabilityCount];//获取商品列表List<AdPrizeInfo> prizeInfoList = prizeInfoService.getPrizeInfo();int num = 0;//循环所有商品for (AdPrizeInfo prize : prizeInfoList) {Integer probability = prize.getOdds();//循环商品概率for (int i = 0; i < probability; i++) {prizesId[num] = prize.getId();num ++;}}//随机⼀个数字int index = (int) (Math.random() * probabilityCount);//获取到随机商品IDString prizeId = prizesId[index];优化⽅法设计思路以上⽅法如果⼤概率的话，是很吃内存的，整理优化为⼀下⽅法：使⽤范围算法//定义中奖率分母百分之int probabilityCount = 100;//最⼩概率值String min = "min";//最⼤概率值String max = "max";Integer tempInt = 0;//待中奖商品数组Map<String,Map<String,Integer>> prizesMap = new HashMap<>(); //获取商品列表List<AdPrizeInfo> prizeInfoList = prizeInfoService.getPrizeInfo(); for (AdPrizeInfo prize : prizeInfoList) {Map<String,Integer> oddsMap = new HashMap<>();//最⼩概率值oddsMap.put(min,tempInt);tempInt = tempInt + prize.getOdds();//最⼤概率值oddsMap.put(max,tempInt);prizesMap.put(prize.getId(),oddsMap);}//随机⼀个数字int index = (int) (Math.random() * probabilityCount);AdPrizeInfo prizeInfo = null;Set<String> prizesIds = prizesMap.keySet();for(String prizesId : prizesIds){Map<String,Integer> oddsMap = prizesMap.get(prizesId);Integer minNum = oddsMap.get(min);Integer maxNum = oddsMap.get(max);//校验index 再哪个商品概率中间if(minNum <= index && maxNum > index){prizeInfo = prizeInfoService.selectByPrimaryKey(prizesId);break;}}//如果为空，则没中奖if(prizeInfo == null){prizeInfo = null;}。

javascript实现随机抽奖功能javascript实现随机抽奖，供⼤家参考，具体内容如下⾸先创建⼀个数组⽤于存放抽奖的参与者：var arr=['张三','波波','kk','莉莉','张三丰','刘德华','周杰困','你那⼉','zhere','好的'];给开始和结束按钮div添加点击事件：//添加点击开始则开始循环播放document.getElementById("start").addEventListener("click",va);//点击停⽌则停⽌播放并显⽰恭喜中奖document.getElementById("end").addEventListener("click",function (){count++;clearTimeout(i);var name=arr[thisone];arr.splice(thisone,1);var get=document.getElementById("get");get.innerHTML=get.innerHTML+'<br>';get.innerText=get.innerText+`${count}. `+name;})⽤setTimeout实现循环事件，每隔100毫秒就执⾏⼀次循环，随机得到存放参与者的数组的长度之间的随机数，不断修改innerText实现⽤户滚动效果：//循环事件function va(){let num=arr.length;console.log(num);if(num===0){clearTimeout(i);//移除开始事件document.getElementById("start").removeEventListener("click",va);document.getElementById("show").innerText="没有了";return;}setTimeout("show()",100);}//获得当前名字下标function getindex() {return parseInt(Math.random()*arr.length);}//循环播放列表function show(){thisone=getindex();document.getElementById("show").innerText=arr[thisone];i=setTimeout("show()",100);}实现的最终效果图如下：当点击开始时：当点击暂停时：以上就是本⽂的全部内容，希望对⼤家的学习有所帮助，也希望⼤家多多⽀持。

用JavaScript编程语言编写随机选择抽奖程序示例文章标题：用JavaScript编程语言编写随机选择抽奖程序示例介绍内容：抽奖活动是一种常见的活动形式，而编程语言可以帮助我们实现自动化的随机选择抽奖程序。

本文将介绍如何使用JavaScript 编程语言编写一个简单而实用的随机选择抽奖程序示例。

首先，我们需要在HTML页面中创建一个抽奖按钮和一些候选人的列表，如下所示：```html<!DOCTYPE html><html><head><title>随机选择抽奖程序示例</title></head><body><h1>随机选择抽奖程序示例</h1><button onclick="selectWinner()">抽奖按钮</button><ul id="candidates"><li>候选人1</li><li>候选人2</li><li>候选人3</li><li>候选人4</li><!--可以继续添加更多候选人--></ul><h2 id="winner"></h2><script src="script.js"></script></body></html>```在上述HTML页面中，我们创建了一个抽奖按钮，并在<ul>标签中列出了一些候选人的姓名。

点击抽奖按钮后，我们将在JavaScript代码中编写逻辑来随机选择一个候选人作为获奖者，并将结果显示在<h2>标签中。
