微信小程序源码解说：石头剪刀布（附源码下载）

2025-02-11 技术教程

昨天看有个石头剪刀布的练习，就拿出来做了一下，布局的代码浪费了很多时间，果然CSS这块的还不是很熟练,下面直接上图上代码了。

JS：

var numAi = 0
var timer
Page({
data:{
//控制按钮是否可点击
btnState:false,
//记录获胜次数
winNum:0,
//中间的话“Ho~ You Win”
gameOfPlay:'',
//用户选择的图片
p_w_picpathUserScr:'/pages/p_w_picpath/wenhao.png',
//电脑随机的图片
p_w_picpathAiScr:'',
//石头剪刀布图片数组
srcs:[
'/pages/p_w_picpath/shitou.png',
'/pages/p_w_picpath/jiandao.png',
'/pages/p_w_picpath/bu.png'
]
},
//生命周期，刚进来
onLoad: function () {
//获取本地缓存“已经获胜的次数”
var oldWinNum = wx.getStorageSync('winNum');
//如果有缓存，那么赋值，否则为0
if(oldWinNum != null && oldWinNum !=''){
this.data.winNum = oldWinNum;
}
this.timerGo();
},
//点击按钮
changeForChoose(e){
console.log();
if(this.data.btnState == true){
return;
}
//获取数组中用户的，石头剪刀布相应的图片。
this.setData({
p_w_picpathUserScr:this.data.srcs[e.currentTarget.id]
});
//清除计时器
clearInterval(timer);
//获取数据源
var user = this.data.p_w_picpathUserScr;
var ai = this.data.p_w_picpathAiScr;
var num = this.data.winNum;
var str = '0.0~\nYou Lost!';
//判断是否获胜
if( user == "/pages/p_w_picpath/shitou.png" && ai == "/pages/p_w_picpath/jiandao.png"){
//获胜后增加次数、改变文字内容、从新缓存获胜次数
num++;
str = 'Ho~\nYou Win!';
wx.setStorageSync('winNum', num);
};
if(user == "/pages/p_w_picpath/jiandao.png" && ai == "/pages/p_w_picpath/bu.png"){
num++;
str = 'Ho~\nYou Win!';
wx.setStorageSync('winNum', num);
};
if(user== "/pages/p_w_picpath/bu.png" && ai == "/pages/p_w_picpath/shitou.png"){
num++;
str = 'Ho~\nYou Win!';
wx.setStorageSync('winNum', num);
};
//如果平局
if(user == ai){
str = 'Game Draw!';
}
//刷新数据
this.setData({
winNum:num,
gameOfPlay:str,
btnState:true
});
},
//开启计时器
timerGo(){
timer = setInterval(this.move,100);
},
//ai滚动方法
move(){
//如果大于等于3，重置
if(numAi>=3){
numAi=0;
}
this.setData({
//获取数组中Ai的，石头剪刀布相应的图片。
p_w_picpathAiScr: this.data.srcs[numAi],
})
numAi++;
},
again(){
//控制按钮
if(this.data.btnState == false){
return;
}
//从新开始计时器
this.timerGo();
//刷新数据
this.setData({
btnState:false,
gameOfPlay:'',
p_w_picpathUserScr:'/pages/p_w_picpath/wenhao.png'
});
}
})
