Question

var movie = prompt("Type the movie title you want reviewed");
var getReview = function(movie){
switch(movie){
    case 'Matrix':
        return "good trip out";
        break;
    case 'Princess Bride':
        return "awesome date night movie";
        break;
    case 'Welcome to America':
        return "Amjad's favorite";
        break;
    case 'Remember the Titans':
        return "love the sports";
        break;
    case 'Why do I look like I'm 12?':
        return "The Ryan and Zach story";
        break;
    case 'Fighting Kangaroos in the wild':
        return "Token Australian movie for Leng";
        break;
    default:
        return "I don't know!";
    }
};

当我提交上面的代码时，我收到错误消息：SyntaxError - missing：在case标签之后。语法有什么问题？

Answer 1

更改

case 'Why do I look like I'm 12?':

到

case 'Why do I look like I\'m 12?':

Answer 2

引用'Why do I look like I'm 12?':至'Why do I look like I\'m 12?':。此外，返回后您不需要break

Answer 3

case 'Why do I look like I'm 12?':

将其改为：

case 'Why do I look like I\'m 12?':

你有引用问题

Answer 4

JS认为你正在关闭Why do I look like I'的字符串。为避免这种情况，您必须使用\：

来转义撇号

case 'Why do I look like I\'m 12?':

嵌套在函数中的JavaScript switch语句
