当悬停父绝对div的子元素而没有jQuery时，防止onmouseout

function onMouseOut(event) { //this is the original element the event handler was assigned to var e = event.toElement || event.relatedTarget; if (e.parentNode == this || e == this) {    return; }        alert('MouseOut');        // handle mouse event here!    }    document.getElementById('parent').addEventListener('mouseout',onMouseOut,true);

我制作了一个快速的JsFiddle演示，其中包含所有需要的CSS和HTML，请查看…

注意 ，这仅检查直接父级，如果父级div嵌套了子级，则您必须以某种方式遍历父级元素以寻找“原始元素”

function makeMouseOutFn(elem){    var list = traverseChildren(elem);    return function onMouseOut(event) {        var e = event.toElement || event.relatedTarget;        if (!!~list.indexOf(e)) { return;        }        alert('MouseOut');        // handle mouse event here!    };}//using closure to cache all child elementsvar parent = document.getElementById("parent");parent.addEventListener('mouseout',makeMouseOutFn(parent),true);//quick and dirty DFS children traversal, function traverseChildren(elem){    var children = [];    var q = [];    q.push(elem);    while (q.length > 0) {      var elem = q.pop();      children.push(elem);      pushAll(elem.children);    }    function pushAll(elemArray){      for(var i=0; i < elemArray.length; i++) {        q.push(elemArray[i]);      }    }    return children;}
