基于这个答案，我在React组件中这样做:

export default React.memo(() => {
    const containerRef = React.useRef(null);

    React.useEffect(() => {
        document.addEventListener('mousedown', handleMouseMove);

        return () => document.removeEventListener('mousedown', handleMouseMove);
    }, []);

    const handleMouseMove = React.useCallback(() => {
        const drag = (e) => {
            console.log('mouse is moving');
        };

        const lift = (e) => {
            console.log('mouse move ended');
            window.removeEventListener('mousemove', drag);
            window.removeEventListener('mouseup', this);
        };

        window.addEventListener('mousemove', drag);
        window.addEventListener('mouseup', lift);
    }, []);

    return (
        <div style={{ width: '100vw', height: '100vh' }} ref={containerRef} />
    );
})

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)

如果你已经在使用jQuery:

var $body = $('body');
$body.on('mousedown', function (evt) {
  $body.on('mouseup mousemove', function handler(evt) {
    if (evt.type === 'mouseup') {
      // click
    } else {
      // drag
    }
    $body.off('mouseup mousemove', handler);
  });
});

正如mrjrdnthms在他对接受的答案的评论中指出的那样，这不再适用于Chrome(它总是触发鼠标移动)，我已经改编了Gustavo的答案(因为我使用jQuery)来解决Chrome的行为。

var currentPos = [];

$(document).on('mousedown', function (evt) {

   currentPos = [evt.pageX, evt.pageY]

  $(document).on('mousemove', function handler(evt) {

    currentPos=[evt.pageX, evt.pageY];
    $(document).off('mousemove', handler);

  });

  $(document).on('mouseup', function handler(evt) {

    if([evt.pageX, evt.pageY].equals(currentPos))
      console.log("Click")
    else
      console.log("Drag")

    $(document).off('mouseup', handler);

  });

});

Array.prototype.equals函数来自这个答案

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>

这应该能很好地工作。类似于已接受的答案(虽然使用jQuery)，但只有当新的鼠标位置与mousedown事件上的位置不同时，isdrag标志才会重置。与公认的答案不同，这适用于最新版本的Chrome，无论鼠标是否移动，鼠标移动都会被触发。

var isDragging = false;
var startingPos = [];
$(".selector")
    .mousedown(function (evt) {
        isDragging = false;
        startingPos = [evt.pageX, evt.pageY];
    })
    .mousemove(function (evt) {
        if (!(evt.pageX === startingPos[0] && evt.pageY === startingPos[1])) {
            isDragging = true;
        }
    })
    .mouseup(function () {
        if (isDragging) {
            console.log("Drag");
        } else {
            console.log("Click");
        }
        isDragging = false;
        startingPos = [];
    });

你也可以在鼠标移动中调整坐标检查，如果你想增加一点公差(即将微小的移动视为点击，而不是拖动)。
