如何将我的摇滚，纸张，剪刀游戏嵌入按钮？

<!DOCTYPE html>

<html>


<button onclick="rockPaperScissors()">Click me</button>



<script  type="text/javascript">
var rockPaperScissors(
var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
if (computerChoice < 0.34) {
    computerChoice = "rock";
} else if(computerChoice <= 0.67) {
    computerChoice = "paper";
} else {
    computerChoice = "scissors";
} console.log("Computer: " + computerChoice);


var compare = function(choice1, choice2) {
if (choice1 === choice2) {
    confirm("The result is a tie!";)
    }
    else if(choice1 === "rock") {
    if (choice2 === "scissors") {
        confirm("rock wins";)
    }
    else {
        confirm("paper wins";)
    }
}

//second one

    else if(choice1 === "paper") {
    if (choice2 === "rock") {
        confirm("paper wins";)
    }
    else {
        confirm("scissors wins";)
    }
}

//third one

    else if(choice1 === "scissors") {
    if (choice2 === "rock") {
        confirm("rock wins";)
    }
    else {
        confirm("scissors wins";)
    }
}
};

)

</script>

Answer 1

您的问题在这里：

var rockPaperScissors(

您需要rockPaperScissors作为函数，而不是变量。

尝试使用以下代码使rockPaperScissors成为一个函数：

function rockPaperScissors() {}

或

var rockPaperScissors = function() {}

然后将相关代码放在大括号内（{ }）。

Answer 2

您尚未正确声明rockPaperScissors功能。因此，当程序试图调用它时，它不起作用。

尝试

function rockPaperScissors() {
  // put your code in here
}

Answer 3

还有更多的拼写错误...更正后的代码包括脚本var rockPaperScissors = function(){的第一行，并且确认应始终如confirm("paper wins");

<!DOCTYPE html>

<html>


<button onclick="rockPaperScissors()">Click me</button>



<script  type="text/javascript">
var rockPaperScissors = function(){
var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
if (computerChoice < 0.34) {
	computerChoice = "rock";
} else if(computerChoice <= 0.67) {
	computerChoice = "paper";
} else {
	computerChoice = "scissors";
} console.log("Computer: " + computerChoice);


var compare = function(choice1, choice2) {
if (choice1 === choice2) {
    confirm("The result is a tie!");
    }
    else if(choice1 === "rock") {
    if (choice2 === "scissors") {
        confirm("rock wins");
    }
    else {
        confirm("paper wins");
    }
}

//second one

    else if(choice1 === "paper") {
    if (choice2 === "rock") {
        confirm("paper wins");
    }
    else {
        confirm("scissors wins");
    }
}

//third one

    else if(choice1 === "scissors") {
    if (choice2 === "rock") {
        confirm("rock wins");
    }
    else {
        confirm("scissors wins");
