对于在大多数情况下都有效的更简单的纯CSS解决方案，可以通过将子指针事件设置为none来删除它们

.parent * {
     pointer-events: none;
}

浏览器支持IE11+

在Angular 5、6和7上

<div (mouseout)="onMouseOut($event)"
     (mouseenter)="onMouseEnter($event)"></div>

然后在

import {Component,Renderer2} from '@angular/core';
...
@Component({
 selector: 'app-test',
 templateUrl: './test.component.html',
 styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit, OnDestroy {
...
 public targetElement: HTMLElement;

 constructor(private _renderer: Renderer2) {
 }

 ngOnInit(): void {
 }

 ngOnDestroy(): void {
  //Maybe reset the targetElement
 }

 public onMouseEnter(event): void {
  this.targetElement = event.target || event.srcElement;
  console.log('Mouse Enter', this.targetElement);
 }

 public onMouseOut(event): void {
  const elementRelated = event.toElement || event.relatedTarget;
  if (this.targetElement.contains(elementRelated)) {
    return;
  }
  console.log('Mouse Out');
 }
}

下面是一个基于下面内容的更优雅的解决方案。 它解释了从一个以上层次的孩子中冒出来的事件。 它还考虑了跨浏览器的问题。

function onMouseOut(this, event) {
//this is the original element the event handler was assigned to
   var e = event.toElement || event.relatedTarget;

//check for all children levels (checking from bottom up)
while(e && e.parentNode && e.parentNode != window) {
    if (e.parentNode == this||  e == this) {
        if(e.preventDefault) e.preventDefault();
        return false;
    }
    e = e.parentNode;
}

//Do something u need here
}

document.getElementById('parent').addEventListener('mouseout',onMouseOut,true);

var elem = $('#some-id');
elem.mouseover(function () {
   // Some code here
}).mouseout(function (event) {
   var e = event.toElement || event.relatedTarget;
   if (elem.has(e).length > 0) return;

   // Some code here
});

感谢阿姆贾德·马萨德，他激励了我。

我有以下解决方案，似乎在IE9, FF和Chrome和代码很短(没有复杂的闭包和横向子东西):

    DIV.onmouseout=function(e){
        // check and loop relatedTarget.parentNode
        // ignore event triggered mouse overing any child element or leaving itself
        var obj=e.relatedTarget;
        while(obj!=null){
            if(obj==this){
                return;
            }
            obj=obj.parentNode;
        }
        // now perform the actual action you want to do only when mouse is leaving the DIV
    }

使用onmouseleave。

或者，在jQuery中使用mouseleave()

这正是你要找的东西。例子:

<div class="outer" onmouseleave="yourFunction()">
    <div class="inner">
    </div>
</div>

或者，在jQuery中:

$(".outer").mouseleave(function(){
    //your code here
});

这里有一个例子。
