Javascript对象，我做错了什么？

Question

我在编码练习中有以下代码。当我尝试提交时，我得到了

  

SyntaxError：意外的字符串

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

你实际上只是错过了movieObj对象的第二项的逗号。用。替换第二行 "Finding Nemo": "Cool animation, and funny turtles.", /* Notice the comma */之后应该可以正常工作。

Answer 2

在“... turtles”对象属性与,

分隔后，您忘记了逗号

Answer 3

您movieObj "Finding Nemo"中遗漏了逗号;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!"

function forEach(array, action) {
    for (var i = 0; i< array.length; i++)
        action(array[i]); // array[i] is the argument
}
