Javascript 对象，我做错了什么？

Question

我有以下来自编码练习的代码。当我尝试提交时，我得到

SyntaxError: Unexpected string

var movieObj = {
"Toy Story 2": "Great story. Mean prospector.",
"Finding Nemo": "Cool animation, and funny turtles."
"The Lion King": "Great songs."
};

var getReview = function (movie) {
    if (movie in movieObj) {
        return movieObj[movie]
    } else {
        return "I don't know!"
    }
};

getReview("Toy Story 2") //expected = "Great story. Mean prospector."
getReview("Toy Story") //expected = " don't know!"

我做错了什么？

Answer 1

您实际上只是缺少 movieObj 对象的第二项的逗号。将第二行替换为 "Finding Nemo": "Cool animation, and funny turtles.", /* Notice the comma */ 之后它应该可以正常工作。

Answer 2

您忘记在“... turtles”之后用逗号分隔对象属性 ,

Answer 3

您在 movieObj 中遗漏了 "Finding Nemo" 的逗号此外，您还遗漏了一些分号 ;

var movieObj = {
    "Toy Story 2": "Great story. Mean prospector.",
    "Finding Nemo": "Cool animation, and funny turtles.",
    "The Lion King": "Great songs."
};

var getReview = function (movie) {
    if (movie in movieObj) {
        alert(movieObj[movie]);
    } else {
        alert("I don't know!");
    }
};

getReview("Toy Story 2"); //expected = "Great story. Mean prospector."
getReview("Toy Story"); //expected = " don't know!"
