再加上这个答案。这个增加了对鼠标事件的支持，用于桌面测试:

<!--scripts-->
class SwipeEventDispatcher {
    constructor(element, options = {}) {
        this.evtMap = {
            SWIPE_LEFT: [],
            SWIPE_UP: [],
            SWIPE_DOWN: [],
            SWIPE_RIGHT: []
        };

        this.xDown = null;
        this.yDown = null;
        this.element = element;
        this.isMouseDown = false;
        this.listenForMouseEvents = true;
        this.options = Object.assign({ triggerPercent: 0.3 }, options);

        element.addEventListener('touchstart', evt => this.handleTouchStart(evt), false);
        element.addEventListener('touchend', evt => this.handleTouchEnd(evt), false);
        element.addEventListener('mousedown', evt => this.handleMouseDown(evt), false);
        element.addEventListener('mouseup', evt => this.handleMouseUp(evt), false);
    }

    on(evt, cb) {
        this.evtMap[evt].push(cb);
    }

    off(evt, lcb) {
        this.evtMap[evt] = this.evtMap[evt].filter(cb => cb !== lcb);
    }

    trigger(evt, data) {
        this.evtMap[evt].map(handler => handler(data));
    }

    handleTouchStart(evt) {
        this.xDown = evt.touches[0].clientX;
        this.yDown = evt.touches[0].clientY;
    }

    handleMouseDown(evt) {
        if (this.listenForMouseEvents==false) return;
        this.xDown = evt.clientX;
        this.yDown = evt.clientY;
        this.isMouseDown = true;
    }

    handleMouseUp(evt) {
        if (this.isMouseDown == false) return;
        const deltaX = evt.clientX - this.xDown;
        const deltaY = evt.clientY - this.yDown;
        const distMoved = Math.abs(Math.abs(deltaX) > Math.abs(deltaY) ? deltaX : deltaY);
        const activePct = distMoved / this.element.offsetWidth;

        if (activePct > this.options.triggerPercent) {
            if (Math.abs(deltaX) > Math.abs(deltaY)) {
                deltaX < 0 ? this.trigger('SWIPE_LEFT') : this.trigger('SWIPE_RIGHT');
            } else {
                deltaY > 0 ? this.trigger('SWIPE_UP') : this.trigger('SWIPE_DOWN');
            }
        }
    }

    handleTouchEnd(evt) {
        const deltaX = evt.changedTouches[0].clientX - this.xDown;
        const deltaY = evt.changedTouches[0].clientY - this.yDown;
        const distMoved = Math.abs(Math.abs(deltaX) > Math.abs(deltaY) ? deltaX : deltaY);
        const activePct = distMoved / this.element.offsetWidth;

        if (activePct > this.options.triggerPercent) {
            if (Math.abs(deltaX) > Math.abs(deltaY)) {
                deltaX < 0 ? this.trigger('SWIPE_LEFT') : this.trigger('SWIPE_RIGHT');
            } else {
                deltaY > 0 ? this.trigger('SWIPE_UP') : this.trigger('SWIPE_DOWN');
            }
        }
    }
}

// add a listener on load
window.addEventListener("load", function(event) {
    const dispatcher = new SwipeEventDispatcher(document.body);
    dispatcher.on('SWIPE_RIGHT', () => { console.log('I swiped right!') })
    dispatcher.on('SWIPE_LEFT', () => { console.log('I swiped left!') })
});

在这里的建议之上，我将跟踪手指号码，因为如果你同时用两个手指触摸，它将获得X位置，而不会导致一个奇怪的行为，而且，你可能想要设置一个“距离”最小值，这样用户在通过你的网站或应用程序触摸时就不会错误地触发滑动。

//Swipe 
let touchstartX = 0
let touchendX = 0
let fingerCount = 0
    
const checkDirection = () => {

  const distance = 50 //Minimum distance for the swipe to work

  //left
  if (touchendX < touchstartX && (touchstartX - touchendX) > distance ){

  //Do something cool
   
  } 
  //right
  if (touchendX > touchstartX && (touchendX - touchstartX) > distance){

    //Do something cooler
}

document.addEventListener('touchstart', e => {

    fingerCount = e.touches.length
    touchstartX = e.changedTouches[0].clientX  
     
})

document.addEventListener('touchend', e => {

    touchendX = e.changedTouches[0].clientX
    if(fingerCount === 1){ 
        checkDirection() 
    }

})

简单的JS代码示例:

document.addEventListener('touchstart', handleTouchStart, false);        
document.addEventListener('touchmove', handleTouchMove, false);

var xDown = null;                                                        
var yDown = null;

function getTouches(evt) {
  return evt.touches ||             // browser API
         evt.originalEvent.touches; // jQuery
}                                                     
                                                                         
function handleTouchStart(evt) {
    const firstTouch = getTouches(evt)[0];                                      
    xDown = firstTouch.clientX;                                      
    yDown = firstTouch.clientY;                                      
};                                                
                                                                         
function handleTouchMove(evt) {
    if ( ! xDown || ! yDown ) {
        return;
    }

    var xUp = evt.touches[0].clientX;                                    
    var yUp = evt.touches[0].clientY;

    var xDiff = xDown - xUp;
    var yDiff = yDown - yUp;
                                                                         
    if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
        if ( xDiff > 0 ) {
            /* right swipe */ 
        } else {
            /* left swipe */
        }                       
    } else {
        if ( yDiff > 0 ) {
            /* down swipe */ 
        } else { 
            /* up swipe */
        }                                                                 
    }
    /* reset values */
    xDown = null;
    yDown = null;                                             
};

Android测试。

简单的水平滑动JS示例:

let touchstartX = 0
let touchendX = 0
    
function checkDirection() {
  if (touchendX < touchstartX) alert('swiped left!')
  if (touchendX > touchstartX) alert('swiped right!')
}

document.addEventListener('touchstart', e => {
  touchstartX = e.changedTouches[0].screenX
})

document.addEventListener('touchend', e => {
  touchendX = e.changedTouches[0].screenX
  checkDirection()
})

垂直滑动也可以使用相同的逻辑。

我将这里的一些答案合并到一个脚本中，该脚本使用CustomEvent在DOM中触发滑动事件。添加0.7k的swiped-events.min.js脚本到你的页面，并监听滑动事件:

刷卡

document.addEventListener('swiped', function(e) {
    console.log(e.target); // the element that was swiped
    console.log(e.detail.dir); // swiped direction
});

swiped-left

document.addEventListener('swiped-left', function(e) {
    console.log(e.target); // the element that was swiped
});

swiped-right

document.addEventListener('swiped-right', function(e) {
    console.log(e.target); // the element that was swiped
});

swiped-up

document.addEventListener('swiped-up', function(e) {
    console.log(e.target); // the element that was swiped
});

swiped-down

document.addEventListener('swiped-down', function(e) {
    console.log(e.target); // the element that was swiped
});

你也可以直接附加到一个元素:

document.getElementById('myBox').addEventListener('swiped-down', function(e) {
    console.log(e.target); // the element that was swiped
});

可选配置

您可以指定以下属性来调整页面中的滑动交互功能(这些是可选的)。

<div data-swipe-threshold="10"
     data-swipe-timeout="1000"
     data-swipe-ignore="false">
      Swiper, get swiping!
</div>

要在应用程序范围内设置默认值，请在最顶部的元素上设置配置属性:

<body data-swipe-threshold="100" data-swipe-timeout="250">
    <div>Swipe me</div>
    <div>or me</div>
</body>

一些mod的顶部回答(不能评论…)来处理短滑动

document.addEventListener('touchstart', handleTouchStart, false);        
document.addEventListener('touchmove', handleTouchMove, false);
var xDown = null;                                                        
var yDown = null;                                                        
function handleTouchStart(evt) {                                         
    xDown = evt.touches[0].clientX;                                      
    yDown = evt.touches[0].clientY;                                      
};                                                
function handleTouchMove(evt) {
    if ( ! xDown || ! yDown ) {
        return;
    }

    var xUp = evt.touches[0].clientX;                                    
    var yUp = evt.touches[0].clientY;

    var xDiff = xDown - xUp;
    var yDiff = yDown - yUp;
    if(Math.abs( xDiff )+Math.abs( yDiff )>150){ //to deal with to short swipes

    if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
        if ( xDiff > 0 ) {/* left swipe */ 
            alert('left!');
        } else {/* right swipe */
            alert('right!');
        }                       
    } else {
        if ( yDiff > 0 ) {/* up swipe */
            alert('Up!'); 
        } else { /* down swipe */
            alert('Down!');
        }                                                                 
    }
    /* reset values */
    xDown = null;
    yDown = null;
    }
};
