Question

我正在为电视节目写一个随机引用生成器，我的功能有些麻烦。我遇到的问题在于如何在包含引号的对象数组中选择对象的一部分。

randomNum变量可能也有问题，我不确定。 HTML是正确的 - 当我将randomQuote和randomAuthor的变量更改为它们显示的字符串时（但我必须删除数组以使其工作。不确定为什么会这样？）。

我希望有人可以帮助我。谢谢！

$(document).ready(function(){

function getQuote(){
    var quotes = {
        {idNumber: 1, author: "Frank", quote: "I love eggs, Charlie. And I love crabs. And I love boiling denim and banging whores. And I don't care if anyone doesn't like that about me, they don't have to stick around.",}
        {idNumber: 2, author: "Mac", quote: "People change, Frank. Look at me: I went from a tiny twink to the muscle-bound freak you see before you.",}
        {idNumber: 3, author: "Mac", quote: "Hey, warm sun, cool ocean breezes, getting rip shit on ham.",}
        {idNumber: 4, author: "Mac", quote: "As a man who works very hard to maintain a certain level of physical excellence... I find shortcuts insulting.",}
        {idNumber: 5, author: "Dennis", quote: "Dude do you have a boner right now?",}
    }

    var randomNum = Math.floor((Math.random()*quotes.length));
    var randomQuote = "hey";
    var randomAuthor = "oy";


    $(".quote").text(randomQuote);
    $(".author").text(randomAuthor);
}
$(".btn").on("click", function(){
    getQuote();
});
});

Answer 1

以下解决方案是否适合您？

var randomQuote = quotes[randomNum][quote]; 
var randomAuthor = quotes[randomNum][author];

Answer 2

一些问题。您的引号变量必须是一个数组，每个元素需要用逗号分隔。否则，您可以使用quotes[randomNum]访问数组的选定元素。请参阅以下代码以了解功能结果。

$(document).ready(function(){

function getQuote(){
    var quotes = [
        {idNumber: 1, author: "Frank", quote: "I love eggs, Charlie. And I love crabs. And I love boiling denim and banging whores. And I don't care if anyone doesn't like that about me, they don't have to stick around.",},
        {idNumber: 2, author: "Mac", quote: "People change, Frank. Look at me: I went from a tiny twink to the muscle-bound freak you see before you.",},
        {idNumber: 3, author: "Mac", quote: "Hey, warm sun, cool ocean breezes, getting rip shit on ham.",},
        {idNumber: 4, author: "Mac", quote: "As a man who works very hard to maintain a certain level of physical excellence... I find shortcuts insulting.",},
        {idNumber: 5, author: "Dennis", quote: "Dude do you have a boner right now?",}
    ]

    var randomNum = Math.floor((Math.random()*quotes.length));
    var randomQuote = quotes[randomNum].quote;
    var randomAuthor = quotes[randomNum].author;


    $(".quote").text(randomQuote);
    $(".author").text(randomAuthor);
}
$(".btn").on("click", function(){
    getQuote();
});
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="quote"></p>
<p class="author"></p>
<a href="#" class="btn">Get Quote</a>
