js模拟手机屏幕滑动事件

function simulateSwipe(element, startY, endY, duration) {
    const touchStartEvent = new TouchEvent('touchstart', {
        bubbles: true,
        cancelable: true,
        touches: [new Touch({ identifier: Date.now(), target: element, clientY: startY })]
    });
    element.dispatchEvent(touchStartEvent);

    setTimeout(() => {
        const touchMoveEvent = new TouchEvent('touchmove', {
            bubbles: true,
            cancelable: true,
            touches: [new Touch({ identifier: Date.now(), target: element, clientY: endY })]

        element.dispatchEvent(touchMoveEvent);

        const touchEndEvent = new TouchEvent('touchend', {

}

// 使用示例
const elementToSwipe = document.getElementById('swipeElement');
simulateSwipe(elementToSwipe, 100, 300, 500); // 从Y=100滑动到Y=300，持续时间为500毫秒
