Question

我正在努力让一个基本的刽子手游戏工作并继续回归Line 25 unexpected token '}'。

我看了看，我已经取出了括号。我刚刚有那个，但我无法得到任何工作。 }正上方的var remainingletters就是它所说的缺失的var answerArray = []; for (var i = 0; i < word.length; i++) { answerArray[i] = "_", } var remainingLetters = word.length;。

以下是几行：

    return  [self sharedInstances];
}
-(id)init{
    NSLog(@"Only first time Instances using Singleton:");
    self =[super init];
    if(self){

Answer 1

你有一个小错字 - 你在一行的末尾使用逗号，你需要一个分号 -

var answerArray = [];
for (var i = 0; i < word.length; i++) {
    answerArray[i] = "_";
}

var remainingLetters = word.length;

Answer 2

您必须更改此代码

answerArray[i] = "_ ,

到此;

answerArray[i] = "_" ;

我们总是要用分号结束行，你的代码有未完成的行，以逗号结尾，你会因为在结束行之前尝试关闭条件而得到错误。
