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
    }
  });

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);
  });
});

清洁ES2015

Let drag = false; 文档。addEventListener('mousedown'， () => drag = false); 文档。addEventListener('mousemove'， () => drag = true); 文档。addEventListener('mouseup'， () => console.log(拖动?'拖动':'点击'));

正如其他人评论的那样，没有遇到任何bug。

来自@Przemek的回答，

函数listenClickOnly(元素，回调，阈值=10){ 让拖动= 0; 元素。addEventListener('mousedown'， () => drag = 0); 元素。addEventListener('mousemove'， () => drag++); 元素。addEventListener('mouseup'， e => { 如果(拖动<阈值)回调(e); })； ｝ listenClickOnly ( 文档, () => console.log('click')， 10 ）;

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");
});
