我真的是Java语言的新手,我需要有关如何使用Javascript表显示书籍封面缩略图及其标题和价格的帮助。这是我到目前为止所拥有的。
var bookImages = new Array ('images/animals-116x150.jpg', 'images/dog-loves-counting-125x150.jpg', ...);
var bookTitle = new Array ('Animals And Their Families', 'Dog Loves Counting', ...);
var bookDescr = new Array ('...','....');
var authors = new Array ('By Barbara Nascimbeni', 'By Louise Yates', ...);
var coverPrice = new Array ('Hardcover, <b>Price: $5.99 CDN</b></style>; 'Hardcover, <b>Price: $5.99 CDN</b>', ...);
var books = document.getElementById("bookSales");
var a;
var bookContent = '<table>'; *this part contains open table tag, just not showing for some reason*
for (a = 0; a < bookImages.length; a++) {
bookContent += "<tr><td><img src='" + bookImages[a] + "</td>";
bookContent += "<td>" + "<b>" + bookTitle[a] + "</b>" + "<br>" + bookDescr[a] + "<br>" + authors[a] + "<br>" + coverPrice[a] +
"<br><br><br><br><br><br><br><br>" + "</td></tr>";
}
bookContent += "</table>"; *this contains end table tag*
books.innerHTML = bookContent;
最佳答案
您应该只使用一个包含对象的数组。每个对象将代表一本书及其所有属性。然后,您可以在迭代数组时简单地调用book.description
以获得一本书的描述
let books = [{
image: 'image/A.png',
title: 'Mysterious Book',
description: 'foo..faa.',
authors: ['John McFee', 'Jack McGordon'],
coverPrice: 5.99
}, {
image: 'image/B.png',
title: 'What a Book',
description: 'descriptio is life',
authors: ['Gipsy Guy'],
coverPrice: 10.95
}];
let bookSales = document.getElementById('bookSales');
let list = "";
books.forEach(book => {
list += "<tr>";
list += "<td><img src='" + book.image + "'></td>";
list += "<td>" + "<b>" + book.title + "</b>" + "<br>" + book.description + "<br>" + book.authors.join(',') + "<br>" + book.coverPrice + "</td>";
list += "</tr>";
});
bookSales.innerHTML += list;
table,
th,
td {
border: 1px solid black;
}
<table>
<tbody id="bookSales">
</tbody>
</table>
