js判断左右滑动

let startX = 0;
let endX = 0;

const element = document.getElementById('yourElementId');

element.addEventListener('touchstart', function(event) {
    startX = event.touches[0].pageX;
});

element.addEventListener('touchend', function(event) {
    endX = event.changedTouches[0].pageX;
    handleSwipe();
});

function handleSwipe() {
    const threshold = 50; // 最小滑动距离阈值
    if (endX < startX - threshold) {
        console.log('向左滑动');
        // 执行向左滑动的操作
    } else if (endX > startX + threshold) {
        console.log('向右滑动');
        // 执行向右滑动的操作
    }
}
