Question

控制台声明我的代码中有一个意外的{。我多次查看语法，似乎无法找到它。

var userChoice = prompt("Do you choose rock, paper, or scissors?");

var computerChoice = Math.random(1);

if (computerChoice <= 0.33){
    computerChoice = "rock";
} elseif (computerChoice <= 0.67 && computerChoice >= 0.34) {
    computerChoice = "paper";
} else {
    computerChoice = "scissors";
}

Answer 1

它应该是else if（不在一起）

编辑：这是工作代码

var userChoice = prompt("Do you choose rock, paper, or scissors?");

var computerChoice = Math.random(1);

if (computerChoice <= 0.33){
    computerChoice = "rock";
} else if (computerChoice <= 0.67 && computerChoice >= 0.34) {
    computerChoice = "paper";
} else {
    computerChoice = "scissors";
}

Answer 2

elseif之间应该有空格。

var userChoice = prompt("Do you choose rock, paper, or scissors?");

var computerChoice = Math.random(1);

if (computerChoice <= 0.33){
    computerChoice = "rock";
} else if (computerChoice <= 0.67 && computerChoice >= 0.34) {
    computerChoice = "paper";
} else {
    computerChoice = "scissors";
}

Answer 3

问题在于您构成了关键字elseif，可能打算else if。

为了将来参考，控制台还会告诉您错误所在的行;之后调查每一项技术（检查你的拼写，查找含义等）来发现你做错了什么，这相当容易。在这种情况下，非常快速的谷歌搜索＆＃34; javascript elseif＆＃34;得到你there。

哪里出现意外的语法错误？
