Detailed explanation of mouseup event attribute loss in jquery

I am writing js recently, ah, js cross-browser Events are lost too much, and jquery is the same. .

The author recently wrote a demo... This problem has troubled me for a week. . .

The code explains the reason:

$("#div1").mouseup(function(e) {  
    alert(e.target.id);  
});

I really hope to get the ie of the dom object triggered by the object after the mouse is released. ..All elements on the page have ids. . .

Finally solved

$("#div1").mouseup(function(e) {  
    var oEvent=e||event;  
    alert(oEvent.target.id);  
});

Ah, annoying js

document.elementFromPoint(oEvent.pageX,oEvent.pageY).id;//获取di  
  
document.elementFromPoint(oEvent.pageX,oEvent.pageY).tagName;//获取节点tag name
