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);
}

其实就是这么简单

var dragged = false
window.addEventListener('mousedown', function () { dragged = false })
window.addEventListener('mousemove', function () { dragged = true })
window.addEventListener('mouseup', function() {
        if (dragged == true) { return }
        console.log("CLICK!! ")
})

老实说，您不希望添加允许小移动的阈值。以上是正确的，正常的，点击所有桌面界面的感觉。

试试吧。

如果愿意，可以轻松添加事件。

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)

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。

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
    }
  });

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");
});
