當我在函數外部定義函數時，無法訪問 glide 參數：export const setFocusListenersForKeyboardNavigation = (glide) => {    const slides = glide._c.Html.slides;    for (let i = 0; i < slides.length; i++) {        const currentSlide = slides[i];        const slideButton = currentSlide.querySelector(".js-slide-button");        const slideLink = currentSlide.querySelector(".js-slide-link");        slideButton && slideButton.addEventListener('focus', focusListener);        slideLink && slideLink.addEventListener('focus', focusListener);    }};const focusListener = (event) => {    const activeIndex = glide._i;    const buttonIndex = event.target.dataset.slideIndex;    if (activeIndex !== parseInt(buttonIndex)) {        glide.go(`=${buttonIndex}`);    }};因此，我做了類似的事情：export const setFocusListenersForKeyboardNavigation = (glide) => {    const focusListener = (event) => {        const activeIndex = glide._i;        const buttonIndex = event.target.dataset.slideIndex;        if (activeIndex !== parseInt(buttonIndex)) {            glide.go(`=${buttonIndex}`);        }    };    const slides = glide._c.Html.slides;    for (let i = 0; i < slides.length; i++) {        const currentSlide = slides[i];        const slideButton = currentSlide.querySelector(".js-slide-button");        const slideLink = currentSlide.querySelector(".js-slide-link");        slideButton && slideButton.addEventListener('focus', focusListener);        slideLink && slideLink.addEventListener('focus', focusListener);    }};我想知道這是黑客還是好的做法？有沒有更方便的方法來做到這一點。
