<h2>抽奖软件</h2>
<p>在浏览器上运行的抽奖程序</p>
<h3>操作方便</h3>
<p>抽奖过程全键盘操作, 只需要按回车(Enter)键即可, 类似播放PPT幻灯片, 非常简单.</p>
<h3>配置灵活</h3>
<p>可配置的选项有: 活动标题, 奖项, 候选人, 摇奖时的跳转速度, 背景图片. 其中, 每一个奖项, 可以一次开完, 也可以一次只开一部分. 例如, 三等奖一共6个, 每次只开2个, 需要开3次才能开完三等奖, 增加娱乐性. 图片可以更换为带自己公司Logo的图片, 以便适应当前节日, 所以, 本抽奖程序任何节日的任何类似的抽奖节目都可使用.</p>
<h3>抽奖流程</h3>
<pre>
等待开始
开场(open): 奖项介绍
奖项循环: 如果多于一个奖项, 则循环
奖项开场(step_open)
摇奖循环: 如果不是一次开完一个奖项, 则循环
摇奖开始(rotate_start)
摇奖结束(rotate_stop)
奖项结束(step_close): 单项中奖名单
闭场(close)
