我认为区别在于，在拖拽中，mousedown和mouseup之间有一个鼠标移动，但在点击中没有。

你可以这样做:

const element = document.createElement('div') element.innerHTML = 'test' document.body.appendChild(element) let moved let downListener = () => { moved = false } element.addEventListener('mousedown', downListener) let moveListener = () => { moved = true } element.addEventListener('mousemove', moveListener) let upListener = () => { if (moved) { console.log('moved') } else { console.log('not moved') } } element.addEventListener('mouseup', upListener) // release memory element.removeEventListener('mousedown', downListener) element.removeEventListener('mousemove', moveListener) element.removeEventListener('mouseup', upListener)

很简单，

el = document.getElementById("your_id"); var isDown = false; 埃尔。addEventListener('mousedown'， function () { isDown = true; })； 埃尔。addEventListener('mouseup'， function () { isDown = false; })； 埃尔。addEventListener('鼠标移动'，函数(){ if (isDown) { //你的代码在这里 ｝ })；

如果只是为了过滤掉拖动的情况，这样做:

var moved = false;
$(selector)
  .mousedown(function() {moved = false;})
  .mousemove(function() {moved = true;})
  .mouseup(function(event) {
    if (!moved) {
        // clicked without moving mouse
    }
  });

另一个基于类的香草JS使用距离阈值的解决方案

private initDetectDrag(element) {
    let clickOrigin = { x: 0, y: 0 };
    const dragDistanceThreshhold = 20;

    element.addEventListener('mousedown', (event) => {
        this.isDragged = false
        clickOrigin = { x: event.clientX, y: event.clientY };
    });
    element.addEventListener('mousemove', (event) => {
        if (Math.sqrt(Math.pow(clickOrigin.y - event.clientY, 2) + Math.pow(clickOrigin.x - event.clientX, 2)) > dragDistanceThreshhold) {
            this.isDragged = true
        }
    });
}

在类内部添加(SOMESLIDER_ELEMENT也可以是document为global):

private isDragged: boolean;
constructor() {
    this.initDetectDrag(SOMESLIDER_ELEMENT);
    this.doSomeSlideStuff(SOMESLIDER_ELEMENT);
    element.addEventListener('click', (event) => {
        if (!this.sliderIsDragged) {
            console.log('was clicked');
        } else {
            console.log('was dragged, ignore click or handle this');
        }
    }, false);
}

我认为区别在于，在拖拽中，mousedown和mouseup之间有一个鼠标移动，但在点击中没有。

你可以这样做:

const element = document.createElement('div') element.innerHTML = 'test' document.body.appendChild(element) let moved let downListener = () => { moved = false } element.addEventListener('mousedown', downListener) let moveListener = () => { moved = true } element.addEventListener('mousemove', moveListener) let upListener = () => { if (moved) { console.log('moved') } else { console.log('not moved') } } element.addEventListener('mouseup', upListener) // release memory element.removeEventListener('mousedown', downListener) element.removeEventListener('mousemove', moveListener) element.removeEventListener('mouseup', upListener)

如果您希望检查特定元素的单击或拖动行为，则无需监听主体即可执行此操作。

$(document).ready(function(){ let click; $('.owl-carousel').owlCarousel({ items: 1 }); // prevent clicks when sliding $('.btn') .on('mousemove', function(){ click = false; }) .on('mousedown', function(){ click = true; }); // change mouseup listener to '.content' to listen to a wider area. (mouse drag release could happen out of the '.btn' which we have not listent to). Note that the click will trigger if '.btn' mousedown event is triggered above $('.btn').on('mouseup', function(){ if(click){ $('.result').text('clicked'); } else { $('.result').text('dragged'); } }); }); .content{ position: relative; width: 500px; height: 400px; background: #f2f2f2; } .slider, .result{ position: relative; width: 400px; } .slider{ height: 200px; margin: 0 auto; top: 30px; } .btn{ display: flex; align-items: center; justify-content: center; text-align: center; height: 100px; background: #c66; } .result{ height: 30px; top: 10px; text-align: center; } <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.3.4/owl.carousel.min.js"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.3.4/assets/owl.carousel.min.css" /> <div class="content"> <div class="slider"> <div class="owl-carousel owl-theme"> <div class="item"> <a href="#" class="btn" draggable="true">click me without moving the mouse</a> </div> <div class="item"> <a href="#" class="btn" draggable="true">click me without moving the mouse</a> </div> </div> <div class="result"></div> </div> </div>
