Question

function displayNewsPanel() {
console.log('here')
// Create a variable named 'newsItems' that is a handle to the element with the ID of 'newsPanel'
const newsItems = document.querySelector('#newsPanel')
// This is the array of news that you are to use. Note that it is an array of arrays.
const news =
[

// Use this variable to build the output string that you will then use for the news
let output = ''
// Loop through the news array of arrays. No need for nested loops.
for (let i = 0; i < news.length; i++) {
// Generate the HTML code that you will need to build the news string
// Your code goes here
// Add the output to the newsItem element
newsItems.innerHTML = output

这是javascript。我陷入了生成构建新闻字符串所需的HTML代码的困境，我需要output = output + new[I][0]

它应该按这样的格式显示：

命名日，

Lorem ipsum 颜色...，

Answer 1

首先，您需要为如何布局数组中的元素创建一种格式，例如将日期放在段落标签中等等。

稍后您可以创建相同版本的 html 字符串格式，例如。<p>Date, Title, Lorem Ipsum</p> <a href='someusefullink.com'>Sample Link</a>，然后将其附加到输出字符串并设置所请求元素的 innerHTML。上面的代码应如下所示：

let output = '';
for (let i = 0; i < news.length; i++) {
output += `<p>${news[i][0]}, ${news[i][1]} ${news[i][2]}</p> <a href='${news[i][3]}'>${news[i][3]}</a>`; 
}
newsItems.innerHTML = output;

Answer 2

必须这样写的循环

for (let i = 0; i < news.length; i++) {
output += `${news[i][0]} - ${news[i][1]} - ${news[i][3]}`;
}
