The event is onclick,onmouseover,onmouseout, and so on, the delegate event is an event that was added to an element, but added to someone else to complete the event.Principle: Using bubbling, the event is added to the parent, triggering the execution effect.Benefits: 1, improve performance, thereby improving the user experience.Example: Triggering each Li to change its background color: Adding mouse events on LiWindow.onload = function () { var Oul = document.getElementById ("ul"); var aLi = o

This article introduces the support for ExtJS4.1 shortcut keys. If you need a friend, refer to the following question. One page has two panels and each has a [add (F2)] button. How do you support shortcut keys? Image Diagram First implementationIt should be very simple. ExtJs provides "Ext. util. KeyMap", which is easy to support shortcut keys.Sample Code The Code is as follows: /// Ext. onReady (function (){Var viewport = Ext. create ('ext. container. viewport ',{Layout :{Type: 'vbox ',Align
