原創：微信小程序源碼解說：石頭剪刀布（附源碼下載）

昨天看有個石頭剪刀布的練習，就拿出來作了一下，佈局的代碼浪費了不少時間，果真CSS這塊的還不是很熟練,下面直接上圖上代碼了。

 

 

JS：

var numAi = 0
var timer
Page({
  data:{
    //控制按鈕是否可點擊
    btnState:false,
    //記錄獲勝次數
    winNum:0,
    //中間的話「Ho~ You Win」
    gameOfPlay:'',
    //用戶選擇的圖片
    imageUserScr:'/pages/image/wenhao.png',
    //電腦隨機的圖片
    imageAiScr:'',
    //石頭剪刀布圖片數組
    srcs:[
      '/pages/image/shitou.png',
      '/pages/image/jiandao.png',
      '/pages/image/bu.png'
    ]
  },
  
  //生命週期，剛進來
  onLoad: function () {
    //獲取本地緩存「已經獲勝的次數」
    var oldWinNum = wx.getStorageSync('winNum');
    //若是有緩存，那麼賦值，不然爲0
    if(oldWinNum != null && oldWinNum !=''){
       this.data.winNum = oldWinNum;
    }
    this.timerGo();
  },
  
  //點擊按鈕
  changeForChoose(e){
    console.log();
      if(this.data.btnState == true){
        return;
      }
  
      //獲取數組中用戶的，石頭剪刀布相應的圖片。
      this.setData({
          imageUserScr:this.data.srcs[e.currentTarget.id]
      });
      //清除計時器
      clearInterval(timer);
  
      //獲取數據源
      var user = this.data.imageUserScr;
      var ai = this.data.imageAiScr;
      var num = this.data.winNum;
      var str = '0.0~\nYou Lost!';
  
      //判斷是否獲勝
      if( user == "/pages/image/shitou.png" && ai == "/pages/image/jiandao.png"){
         //獲勝後增長次數、改變文字內容、重新緩存獲勝次數
         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);
      };
  
      //若是平局
      if(user == ai){
         str = 'Game Draw!';
      }
  
      //刷新數據
      this.setData({
          winNum:num,
          gameOfPlay:str,
          btnState:true
      });
  },
  
  //開啓計時器
  timerGo(){
    timer = setInterval(this.move,100);
  },
  
  //ai滾動方法
  move(){
    //若是大於等於3，重置
    if(numAi>=3){
      numAi=0;
    }
    this.setData({
        //獲取數組中Ai的，石頭剪刀布相應的圖片。
        imageAiScr: this.data.srcs[numAi],
    })
    numAi++;
  },
  
  again(){
      //控制按鈕
      if(this.data.btnState == false){
        return;
      }
      //重新開始計時器
      this.timerGo();
      //刷新數據
      this.setData({
          btnState:false,
          gameOfPlay:'',
          imageUserScr:'/pages/image/wenhao.png'
      });
  }
})
