attachEvent 只能得到冒泡阶段 3- addEventListener(type, Listener [,userCapture]) // 第三个参数如果是 true,表示在事件捕获阶段调用事件处理程序;如果是 false(默认),表示在事件冒泡阶段调用事件处理程序 4- 实际开发中,我们很少使用事件捕获 5- 有些事件没有冒泡:onblue, onfocus, on
一、John Resig 所写的 addEvent() 函数:http://ejohn.org/projects/flexible-javascript-events/ functionaddEvent( obj, type, fn ) { if( obj.attachEvent ) { obj['e'+type+fn]=fn; obj[type+fn]=function(){obj['e'+type+fn]( window.event );} obj.attachEvent('on'+type, obj[type+fn...
}//删除事件绑定function unBindEvent(element, eventName, func) {varevents =this['the'+eventName];//如果不存在一个事件序列if(!events) {returnfalse; }//检测该函数是否存在该事件序列当中for(vari=0; i<events.length; i++) {if(func ===events[i]) { [].splice.call(events, i,1);returntr...
removeEventListener('click', fn); } DOM事件流 事件流描述的是从页面中接收事件的顺序。 事件发生时会在元素节点之间按照特定的顺序传播,这个传播过程即DOM事件流。 DOM事件流分为3个阶段: 捕获阶段 当前目标阶段 冒泡阶段 比如我们给一个div注册了点击事件: 事件冒泡:IE最早提出,事件开始时由最具体的元素...

借助共同创作功能,多个人可以共同协作,同时编辑同一个 Excel 工作簿。 对于可由共同创作者触发的事件(如onChanged),相应的Event对象会包含source属性,以指示事件是由当前用户在本地触发 (event.source == Local),还是由远程共同创作者触发 (event.source == Remote)。
elements like buttons or links because, by default, when you add aclickevent listener to them, this will also trigger the event when you use theEnter(for button and links) andSpacekeys (button only). Instead, the utility of thekeydownevent comes when you need to add functionality to ...
