老虎机数字抽奖(可控制结果)
作者:互联网
废话
本篇是一个原生js构造函数,加css3实现的抽奖,在app,h5,小程序,小游戏里都可以直接用,都兼容,先看下是不是你们想要的效果吧,h5,app,小程序里(当然也能自定义图片,不用数字)
普通js,html里
说一下,常用的几种抽奖(转盘,老虎机等),在微信小程序,小游戏,app里,现在到处可见,所以抽奖这个东西,不要抱有幻想中大奖,程序是人写的,我让你中啥你就中啥,
正文
附上代码
html
<div class="game_wrap">
<div class="game_item">
<ul></ul>
</div>
<div class="game_item">
<ul></ul>
</div>
<div class="game_item">
<ul></ul>
</div>
</div>
<div style="text-align: center;">
<button id="btn" class="startBtn" bindtap="start">开始抽奖</button>
</div>
css
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.game_wrap {
width: 240px;
height: 80px;
box-sizing: content-box;
border-radius: 15px;
border: 20px solid #F84438;
overflow: hidden;
margin: 10px auto;
box-shadow: 0px 0px 15px rgba(219, 71, 71, 0.5) inset
}
.game_item {
width: 33.333%;
height: 80px;
float: left;
border-left: 5px solid #F84438
}
.game_item:first-child {
border-left: none
}
.game_item li {
list-style: none;
width: 100%;
height: 80px;
line-height: 80px;
text-align: center;
position: relative;
font-size: 50px;
}
.startBtn{
background:#F84438;
border: none;
padding: 10px 20px;
color: #fff;
font-size: 16px;
cursor: pointer;
margin: 20px auto;
}
js
const LuckGame = (function(win,doc){
class Luck{
constructor(obj) {
this.setting = {
len : 5, //奖品个数
speed : 5000, //滚动时间
circle : 5, //循环几圈
};
this.extend( this.setting, obj );
this.$ul = doc.querySelectorAll('.game_wrap ul');
this.$height = doc.querySelector('.game_item').offsetHeight;
this.setList();
}
setList(){
//填充li
let html = '';
for(let n = 0;n < this.setting.circle;n++){
for(let i = 0;i< this.setting.len;i++){
html+='<li>'+i+'</li>'; //图片这里自己添加img以及修改样式
};
};
;[].forEach.call(this.$ul,(o,i)=>{
o.innerHTML = html;
//设置默认随机显示
o.style['transform']=o.style['-webkit-transform'] = 'translate(0px, -'+Math.floor(Math.random() * this.setting.len) * this.$height+'px) translateZ(0px)';
});
}
start(arr,fn){
let that = this,countNum = 0;
//开始抽奖
;[].forEach.call(that.$ul,(o,i)=>{
setTimeout(()=>{
var y=(arr[i]+that.setting.len *(that.setting.circle-1))*that.$height;
o.style['-webkit-transition'] = that.setting.speed+'ms ease';
o.style['-webkit-transform'] = 'translate(0px, -'+y+'px) translateZ(0px)'
},i * 300);
o.addEventListener('webkitTransitionEnd',function(){
this.style['-webkit-transition'] = '0ms ease';
this.style['-webkit-transform'] = 'translate(0px, -'+arr[i]*that.$height+'px) translateZ(0px)';
countNum++;
if(countNum == that.$ul.length){
fn && fn();
}
},false);
})
}
extend (n,n1){
for(let i in n1){n[i] = n1[i]};
}
}
return Luck;
})(window,document);
var game = new LuckGame({
len : 4,
speed : 3000,
circle : 5,
});
btn.onclick = function(){
game.start([1,1,1],function(){
alert('恭喜你中奖了')
})
}
如果是小程序html 绑定事件修改bingtap,vue同理,改成@click=“start”
html
<button id="btn" class="startBtn" bindtap="start">开始抽奖</button>
js
})(window, document);下加
this.setData({
LuckGame
})
start: function () {
LuckGame = this.data.LuckGame;
var game = new LuckGame({
len: 9,
speed: 3000,
circle: 5,
});
game.start([1, 2, 3], function () {
alert('恭喜你中奖了')
})
},
当然你也可以封装成组件使用,还有小程序,vue专用的一些抽奖组件
补充常用的ui自带的抽奖组件
滚动数字 老虎机抽奖
里面的api特别全
转盘抽奖
还有刮刮卡
里的抽奖组件就更多了,去插件市场一搜,一大把
本人写过一片博客《十分钟写一个好玩的app》用的是uniapp,里面有用到转盘抽奖
总结:
不能控制结果的抽奖组件不是抽奖组件,觉得有用的点个赞啊,谢谢
