尝试mouseleave ()

例子:

<div id="parent" mouseleave="function">
   <div id="child">

   </div>
</div>

;)

有两种方法可以处理这个问题。

1)检查事件。目标结果在你的回调，看看它是否匹配你的父div

var g_ParentDiv;

function OnMouseOut(event) {
    if (event.target != g_ParentDiv) {
        return;
    }
    // handle mouse event here!
};


window.onload = function() {
    g_ParentDiv = document.getElementById("parentdiv");
    g_ParentDiv.onmouseout = OnMouseOut;
};

<div id="parentdiv">
    <img src="childimage.jpg" id="childimg" />
</div>

2)或者使用事件捕获和调用事件。回调函数中的stopPropagation

var g_ParentDiv;

function OnMouseOut(event) {

    event.stopPropagation(); // don't let the event recurse into children

    // handle mouse event here!
};


window.onload = function() {
    g_ParentDiv = document.getElementById("parentdiv");
    g_ParentDiv.addEventListener("mouseout", OnMouseOut, true); // pass true to enable event capturing so parent gets event callback before children
};

<div id="parentdiv">
    <img src="childimage.jpg" id="childimg" />
</div>

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);

简单地，我们可以检查e.relatedTarget是否有子类，如果为真则返回函数。

    if ($(e.relatedTarget).hasClass("ctrl-btn")){
        return;
    }

这是为我工作的代码，我用于html5视频播放，暂停按钮切换悬停视频元素

element.on("mouseover mouseout", function(e) {

    if(e.type === "mouseout"){

        if ($(e.relatedTarget).hasClass("child-class")){
            return;
        }

    }

});

虽然你提到的解决方案使用jquery， Mouseenter和mouseleave是原生dom事件，所以你可以不使用jquery。
