Question

我正在尝试创建一个引用生成器，但是当尝试读取变量时，它会一直返回undefined。我也使用了一个linter来帮助我，因为我在括号内走，这给了我同样的错误。

public class ItemsController
{
    IQueryHandler<PagedQuery<GetAllItemsQuery, Item>, Paged<Item>> handler;

    public ItemsController(
        IQueryHandler<PagedQuery<GetAllItemsQuery, Item>, Paged<Item>> handler)
    {
        this.handler = handler;
    }

    public ActionResult Index(PagedQuery<GetAllItemsQuery, Item> query)
    {
        return View(this.handler.Handle(query));
    }
}

var quote = document.getElementById("quote-here");
var creator = document.getElementById("subscript");
var quoteButton = document.getElementById("quote-btn");
var arr = [
    {"qoute": "Don't cry because it's over, smile because it happened.", "creater": "Dr.Seuss"},
    {"qoute": "Be yourself; everyone else is already taken.", "creater": "Oscar Wilde"},
    {"qoute": "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.", "creater": "Albert Einstein"},
    {"qoute": "So many books, so little time.", "creater": "Frank Zappa"},
    {"qoute": "Be who you are and say what you feel, because those who mind don't matter, and those who matter don't mind.", "creater": "Bernard M. Baruch"},
    {"qoute": "A room without books is like a body without a soul.", "creater": "Marcus Tullius Cicero"},
    {"qoute": "You only live once, but if you do it right, once is enough.", "creater": "Mae West"},
    {"qoute": "Be the change that you wish to see in the world.", "creater": "Mahatma Gandhi"},
    {"qoute": "If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals.", "creater": "J.K. Rowling, Harry Potter and the Goblet of Fire"},
    {"qoute": "Friendship ... is born at the moment when one man says to another 'What! You too? I thought that no one but myself . . .'", "creater": "C.S. Lewis, The Four Loves"},

];
 
function rando(min, max) {
    "use strict";
    return Math.floor(Math.random() * (max - min) + min);
}
 
function generate() {
    "use strict";
    var x = rando(0, 13);
    quote.innerHTML = arr[x].quote;
    creator.innerHTML = "- " + arr[x].quote;
}
 
quoteButton.addEventListener('click', generate);

Answer 1

这是一个错字，你在数组中写了qoute。

Answer 2

这是一个错误的错误。

var quote = document.getElementById("quote-here");
var creator = document.getElementById("subscript");
var quoteButton = document.getElementById("quote-btn");
var arr = [

];

function rando(min, max) {
    return Math.floor(Math.random() * (max - min) + min);
}

function generate() {
    var x = rando(0, 13);
    console.log(arr[x].qoute)
    quote.innerHTML = arr[x].qoute;
    creator.innerHTML = "- " + arr[x].creater;
}

quoteButton.addEventListener('click', generate);

document.getElementById返回undefined
