本次我们来开发石头剪刀布小游戏呀，主要是通过if进行逻辑判断，然后随机函数将值进行随机判断，然后对比输赢，然后统计次数，接下来我们一起来实现实现吧：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 | <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title></title> <link rel="stylesheet" href=""> <script type="text/javascript"></p> <p> var YouWin = 0;</p> <p> function result(You)<br /> {<br /> var Pc = Pc_result(); //获取电脑的选择</p> <p> if(You == Pc)<br /> {<br /> alert("没有输赢,你们出的都是" + Pc);<br /> }</p> <p> else if(You == "剪刀" && Pc == "石头")<br /> {<br /> alert("你输了,电脑出的是" + Pc);<br /> }<br /> else if(You == "布布" && Pc == "石头")<br /> {<br /> alert("你赢了,电脑出的是" + Pc);<br /> YouWin++;<br /> }</p> <p> else if(You == "布布" && Pc == "剪刀")<br /> {<br /> alert("你输了,电脑出的是" + Pc);<br /> }<br /> else if(You == "石头" && Pc == "剪刀")<br /> {<br /> alert("你赢了,电脑出的是" + Pc);<br /> YouWin++;<br /> }</p> <p> else if(You == "石头" && Pc == "布布")<br /> {<br /> alert("你输了,电脑出的是" + Pc);<br /> }<br /> else if(You == "剪刀" && Pc == "布布")<br /> {<br /> alert("你赢了,电脑出的是" + Pc);<br /> YouWin++;<br /> }<br /> document.getElementById("YouWin_text").value = YouWin;<br /> }</p> <p> // 随机电脑出的选择<br /> function Pc_result()<br /> {</p> <p> v1 = Math.random()*3;<br /> v1 = Math.round(v1)+1;</p> <p> if(v1 == 1)<br /> {<br /> return "石头";<br /> }</p> <p> else if(v1 == 2)<br /> {<br /> return "剪刀";<br /> }</p> <p> else if(v1 == 3)<br /> {<br /> return "布布";<br /> }<br /> }</p> <p> </script> <hr> <input type="button" value="石头" onclick="result('石头')"> <input type="button" value="剪刀" onclick="result('剪刀')"> <input type="button" value="布布" onclick="result('布布')"> <hr> <span>你赢的次数:</span> <input type="text" id="YouWin_text"> <span>电脑赢的次数:</span> <input type="text" id="PcWin"> |
