你能帮帮我吗?我做错了什么,所以我无法在不加载页面的情况下检查正确的文章。
我将这行代码标记为可修复。这是部分(/* [FIX THIS?!] 使用选择器('href' 属性的值)找到正确的文章 */
const targetArticle = document.querySelector("href");
console.log("kliknieto: ", targetArticle);) 在此先感谢您的帮助:
"use strict";
function titleClickHandler(event) {
event.preventDefault();
const clickedElement = this;
/* [DONE] remove class 'active' from all article links */

for (let activeLink of activeLinks) {

}
/* [DONE] add class 'active' to the clicked link */

console.log("clickedElement:", clickedElement);
/* [DONE] remove class 'active' from all articles */
