Question

我想把一个摇滚，纸张，剪刀游戏作为JavaScript的初学者。

我的游戏计划是：

用户点击选项（摇滚，纸张，剪刀）后，将显示他们的分数和计算机分数。它会显示结果。一旦他们的分数达到一定数量，他们就可以输入他们的名字并将其记录在某处。

有人可以告诉我如何做到这一点，我是初学者，如果有人能告诉我如何做到这一点会很好。请在JS Fiddle网页上查看; l。我正在整合HTML和CSS。

我是在JSFiddle上做的：https://jsfiddle.net/y3qu7pzz/

由于

enter code here: This is the JS
function playgame (x){

var options = ["rock", "paper", "scissors"]

var playerChoice = x

var randomNumber = Math.floor(Math.random()*options.length)

var computerChoice = options[randomNumber]

function determineWinner(){
	//
	if (playerChoice == computerChoice) {
  	//
  	$("#results").html("You selected " + playerChoice + " and the computer selected " + computerChoice + ". Game tied.<br />")
  } 
  //
  else if (playerChoice == "rock" && computerChoice == "paper" || playerChoice == "scissors" && computerChoice == "rock" || playerChoice == "paper" && computerChoice == "scissors") {
  	//
  	$("#results").html("You selected " + playerChoice + " and the computer selected " + computerChoice + ". You lost. <br />")  	
  } 
  //
  else if (playerChoice == "rock" && computerChoice == "scissors" || playerChoice == "scissors" && computerChoice == "paper" || playerChoice == "paper" && computerChoice == "rock") {
  	//
    $("#results").html("You selected " + playerChoice + " and the computer selected " + computerChoice + ". You won. <br />") 
	} 
  //
  else {
  	//
  	alert("Please enter rock, paper or scissors")
  }
}
//
determineWinner()

} 

$(".start").click(function (){
var choice = $(this).attr("id")
playgame(choice)
})

Answer 1

看起来您的代码正在运行。你说你想把分数存储在某个地方。第一部分将包括适当的分数和增量。您可以存储一个全局变量，其中包含计算机赢得的次数和玩家赢得的次数

var computerWins = 0;
var playerWins = 0;
var draws = 0;

在determineWinner()

//computer wins conditional
computerWins++;
...
//player wins conditional
playerWins++;
//..etc

最终计算得分百分比得分：

var percentageWins = (playerWins / (computerWins + playerWins + draws)) * 100;

向用户显示等。

您可能希望将分数存储在localstorage中，因此如果用户离开页面并返回，则仍然会持续存在。见https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API/Using_the_Web_Storage_API

您想要从localstorage设置/获取胜出/抽奖变量。或者，您可以将数据发布到某个端点并检索它，但这需要额外的服务器。
