嘿朋友们,当页面为 1700 像素或更小时,我正在尝试window.matchMedia("(max-width: 1700px)")
在 html 中添加一些元素。现在我只是想通过在屏幕上显示一个功能警报“哟”来测试它。这和我试图改变的其他事情一样不起作用?有任何想法吗?

const ham = document.querySelector('.nav-box');
const menu = document.querySelector('.menu');
const menuClose = document.querySelector('#menu-close');
const leftArrow = document.querySelector('#left');
const rightArrow = document.querySelector('#right');
const img = document.querySelector('.image-slider');
var x = window.matchMedia("(max-width: 1700px)");
let num = 1;
x.addEventListener(adjustMenuDesign);
adjustMenuDesign(x);
ham.addEventListener('click', function() {
ham.classList.add('ham-open');
menu.style.marginLeft = '50px';
})
menuClose.addEventListener('click', function() {
ham.classList.remove('ham-open');
menu.style.marginLeft = '-700px';
})
leftArrow.addEventListener('click', function() {
num--;
if(num > 0) {
img.style.backgroundImage = 'url(img/fam-' + num + '.jpeg)';
console.log(num);
console.log(img.style.backgroundImage);

num = 4;
img.style.backgroundImage = 'url(img/fam-' + num + '.jpeg)';
