Event delegate: The event is onclick,onmouseover,onmouseout, and so is the event, the delegate, is to let others do, this event is added to some elements, but you add to others to do, complete this event. Principle: Use the bubbling principle to add events to the parent to promote the execution effect.Benefits: 1. Improve performanceWindow.onload = function () { var Oul = document.getElementById ("ul"); var aLi = oul.getelementsbytagname ("li"); for (var i=0; iIn this way, we can add mouse ev
