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)

使用jQuery和5像素x/y暂停来检测拖动:

var dragging = false;
$("body").on("mousedown", function(e) {
  var x = e.screenX;
  var y = e.screenY;
  dragging = false;
  $("body").on("mousemove", function(e) {
    if (Math.abs(x - e.screenX) > 5 || Math.abs(y - e.screenY) > 5) {
      dragging = true;
    }
  });
});
$("body").on("mouseup", function(e) {
  $("body").off("mousemove");
  console.log(dragging ? "drag" : "click");
});

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>

如果你想使用Rxjs:

var element = document; Rx.Observable .merge( Rx.Observable.fromEvent(element, 'mousedown').mapTo(0), Rx.Observable.fromEvent(element, 'mousemove').mapTo(1) ) .sample(Rx.Observable.fromEvent(element, 'mouseup')) .subscribe(flag => { console.clear(); console.log(flag ? "drag" : "click"); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://unpkg.com/@reactivex/rxjs@5.4.1/dist/global/Rx.js"></script>

这是@wong2在他的回答中所做的直接克隆，但转换为RxJs。

样本的使用也很有趣。示例操作符将从源(mousedown和mousemove的合并)中获取最新的值，并在内部观察对象(mouseup)发出时发出它。

所有这些解决方案要么在微小的鼠标移动上失效，要么过于复杂。

下面是一个使用两个事件侦听器的简单适应性解决方案。Delta是您必须在上下事件之间水平或垂直移动的距离(以像素为单位)，以便代码将其归类为拖拽而不是单击。这是因为有时你会在抬起鼠标或手指之前移动几个像素点。

const delta = 6;
let startX;
let startY;

element.addEventListener('mousedown', function (event) {
  startX = event.pageX;
  startY = event.pageY;
});

element.addEventListener('mouseup', function (event) {
  const diffX = Math.abs(event.pageX - startX);
  const diffY = Math.abs(event.pageY - startY);

  if (diffX < delta && diffY < delta) {
    // Click!
  }
});

对于OSM地图上的公共操作(单击时放置标记)，问题是:1)如何确定鼠标向下的持续时间->向上(您无法想象为每次单击创建一个新的标记)2)鼠标向下移动期间->向上(即用户正在拖动地图)。

const map = document.getElementById('map');

map.addEventListener("mousedown", position); 
map.addEventListener("mouseup", calculate);

let posX, posY, endX, endY, t1, t2, action;

function position(e) {

  posX = e.clientX;
  posY = e.clientY;
  t1 = Date.now();

}

function calculate(e) {

  endX = e.clientX;
  endY = e.clientY;
  t2 = (Date.now()-t1)/1000;
  action = 'inactive';

  if( t2 > 0.5 && t2 < 1.5) { // Fixing duration of mouse down->up

      if( Math.abs( posX-endX ) < 5 && Math.abs( posY-endY ) < 5 ) { // 5px error on mouse pos while clicking
         action = 'active';
         // --------> Do something
      }
  }
  console.log('Down = '+posX + ', ' + posY+'\nUp = '+endX + ', ' + endY+ '\nAction = '+ action);    

}
