- 事件流
e.stopPropagation()/return false(只能使用在jq中)
阻止默认事件:return false
- 事件监听
function (obj, eventType, fn) {
if (obj.attachEvent) {
obj.attachEvent('on' + eventType, fn);
} else {
obj.addEventListener(eventType, fn, false);
}
}
- 事件委托
oUl.onmouseover = function (event) {
var event = event || window.event;
var target = event.target||event.srcElement;
var nodeName=target.nodeName;
if(nodeName.toLowerCase()=='li'){
target.style.background = 'green';
}
}
