run above if swiperslides exist in page

To ensure the Swiper instance is initialized only if the `swiperslides` element exists on the page, you can use a conditional check for the element's existence. Here's the modified code:
document.addEventListener('DOMContentLoaded', function () {
var swiperContainer = document.querySelector(".swiperslides");
if (swiperContainer) { // Check if the element exists
var swiper = new Swiper(".swiperslides", {
slidesPerView: 3,
spaceBetween: 30,
pagination: false,
breakpoints: {
0: {
slidesPerView: 1.2,
spaceBetween: 10,
},
1024: {
slidesPerView: 3,
spaceBetween: 30,
}
}
});
}
});### Explanation:
1. `document.querySelector(".swiperslides")`: This checks if the `.swiperslides` element exists on the page.
2. `if (swiperContainer)`: Initializes Swiper only if the element is present, preventing unnecessary execution and potential errors.
This approach ensures your code runs efficiently and avoids errors on pages where the `swiperslides` element is absent.
