有大佬遇到过这个问题吗：window.addEventListener如何判断某个节点之外?

Question

点击的元素不是该div以及该子孙节点,就能促发事件?这个怎么判断?

Answer 1

letbox=document.querySelector('#box')
window.addEventListener('click',(event)=>{
//兼容
constev=window.event||event;
constpath=event.path||(event.composedPath&&event.composedPath());
if(path.includes(box)){
console.log(1)
}else{
console.log(2)
}
})
                            

Answer 2

eventTarget.addEventListener("click",({target})=>{
if(div!==target&&!div.contains(target)){
...
}
});
