微信小程序_石头剪刀布

昨天看 “微信小程序联盟” 这个网站上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
imageUserScr:'/pages/image/wenhao.png',
//电脑随机的图片
imageAiScr:'',
//石头剪刀布图片数组
srcs:[
'/pages/image/shitou.png',
'/pages/image/jiandao.png',
'/pages/image/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({
imageUserScr:this.data.srcs[e.currentTarget.id]
});
//清除计时器
clearInterval(timer);

//获取数据源
var user = this.data.imageUserScr;
var ai = this.data.imageAiScr;
var num = this.data.winNum;
var str = '0.0~\nYou Lost!';

//判断是否获胜
if( user == "/pages/image/shitou.png" && ai == "/pages/image/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/image/jiandao.png" && ai == "/pages/image/bu.png"){
num++;
str = 'Ho~\nYou Win!';
wx.setStorageSync('winNum', num);
};
if(user== "/pages/image/bu.png" && ai == "/pages/image/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。
imageAiScr: 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:'',
imageUserScr:'/pages/image/wenhao.png'
});
}
})
