移动端原生js使用touch事件监听滑动方向
let box = document.querySelector('body') // 监听对象 let startTime = '' // 触摸开始时间 let startDistanceX = '' // 触摸开始X轴位置 let startDistanceY = '' // 触摸开始Y轴位置 let endTime = '' // 触摸结束时间 let endDistanceX = '' // 触摸结束X轴位置 let endDistanceY = '' // 触摸结束Y轴位置 let moveTime = '' // 触摸时间 let moveDistanceX = '' // 触摸移动X轴距离 let moveDistanceY = '' // 触摸移动Y轴距离 box.addEventListener("touchstart", (e) => { startTime = new Date().getTime() startDistanceX = e.touches[0].screenX startDistanceY = e.touches[0].screenY }) box.addEventListener("touchend", (e) => { endTime = new Date().getTime() endDistanceX = e.changedTouches[0].screenX endDistanceY = e.changedTouches[0].screenY moveTime = endTime - startTime moveDistanceX = startDistanceX - endDistanceX moveDistanceY = startDistanceY - endDistanceY console.log(moveDistanceX, moveDistanceY) // 判断滑动距离超过40 且 时间小于500毫秒 if ((Math.abs(moveDistanceX) > 40 || Math.abs(moveDistanceY) > 40) && moveTime < 500) { // 判断X轴移动的距离是否大于Y轴移动的距离 if (Math.abs(moveDistanceX) > Math.abs(moveDistanceY)) { // 左右 console.log(moveDistanceX > 0 ? '左' : '右') } else { // 上下 console.log(moveDistanceY > 0 ? '上' : '下') } } })
