即使在页面刷新时也激活分页选项卡

Question

我希望这个分页选项卡在单击时处于活动状态，甚至在刷新时也应该处于活动状态。就像我在刷新页面时选择了选项卡3一样，它应该在选项卡3上，而不是转到一个。我不打算在HTML中使用onlClik事件，我只想用CSS或Javascript来做。我在本地存储中尝试过，但无法完成。我认为这可以通过本地存储来实现。

是的，可以用localStorage完成。以下是我如何处理它：-

const lastPage = localStorage.getItem('lastPage') || 1;
const lastPageElement = document.querySelector(`.paginate_button [data-dt-idx='${lastPage}']`);
lastPageElement.parentNode.classList.add('active');

const paginationFooter = document.querySelector('.pagination');
paginationFooter.addEventListener('click', (e) => {
const isPage = e.target.dataset.dtIdx;
if (isPage) {
const currentActivePageElement = document.querySelector('.paginate_button.active');
if (currentActivePageElement) currentActivePageElement.classList.remove('active');
e.target.parentNode.classList.add('active');
const currentPage = e.target.dataset.dtIdx;
localStorage.setItem('lastPage', currentPage);
}
})

尽管试着把你的方法也包括在内，这样人们就能告诉你你可能错过了什么。这是一把小提琴，你可以在那里看到演奏。
