[英]Video Touch Slider with HTML, CSS & JavaScript
我最近在玩本教程中的代码展示: Touch Slider CodePen我想使用类似的东西,但使用视频而不是图像。
我交换了 HTML、JS 和 CSS 代码来处理标签。 有了这个,代码就可以工作了,你最初可以滚动一个视频,就像图像工作一样。 在此之后,似乎 js 'isDragging' 或 te JS 中的某些事件似乎冻结了,我无法滑动到另一个视频或图像。
任何人都可以玩这个 CodePen 中显示的 JS 并获得一个带有视频的工作滑块吗?
谢谢!
slides = Array.from(document.querySelectorAll('.slide'))
let isDragging = false,
startPos = 0,
currentTranslate = 0,
prevTranslate = 0,
animationID = 0,
currentIndex = 0
slides.forEach((slide, index) => {
const slideImage = slide.querySelector('video')
slideImage.addEventListener('dragstart', (e) => e.preventDefault())
// Touch events
slide.addEventListener('touchstart', touchStart(index))
slide.addEventListener('touchend', touchEnd)
slide.addEventListener('touchmove', touchMove)
// Mouse events
slide.addEventListener('mousedown', touchStart(index))
slide.addEventListener('mouseup', touchEnd)
slide.addEventListener('mouseleave', touchEnd)
slide.addEventListener('mousemove', touchMove)
})
// Disable context menu
window.oncontextmenu = function (event) {
event.preventDefault()
event.stopPropagation()
return false
}
function touchStart(index) {
return function (event) {
currentIndex = index
startPos = getPositionX(event)
isDragging = true
// https://css-tricks.com/using-requestanimationframe/
animationID = requestAnimationFrame(animation)
slider.classList.add('grabbing')
}
}
function touchEnd() {
isDragging = false
cancelAnimationFrame(animationID)
const movedBy = currentTranslate - prevTranslate
if (movedBy < -100 && currentIndex < slides.length - 1) currentIndex += 1
if (movedBy > 100 && currentIndex > 0) currentIndex -= 1
setPositionByIndex()
slider.classList.remove('grabbing')
}
function touchMove(event) {
if (isDragging) {
const currentPosition = getPositionX(event)
currentTranslate = prevTranslate + currentPosition - startPos
}
}
function getPositionX(event) {
return event.type.includes('mouse') ? event.pageX : event.touches[0].clientX
}
function animation() {
setSliderPosition()
if (isDragging) requestAnimationFrame(animation)
}
function setSliderPosition() {
slider.style.transform = `translateX(${currentTranslate}px)`
}
function setPositionByIndex() {
currentTranslate = currentIndex * -window.innerWidth
prevTranslate = currentTranslate
setSliderPosition()
} ```
将标签替换为和替换JS中的img引用
