求教育 这里的取消冒泡应该怎么写 这样写出来的不管用哇
window.onload=function(){
var aLi=document.getElementsByTagName('li');
for(var i=0; i<aLi.length; i++){
aLi[i].onmouseover=function(event){
var event = event || window.event
if(event.stopPropagation){
event.stopPropagation();}
else{event.cancelBubble = true;};
var aNav = this.getElementsByTagName('ul');
var animate = setInterval(function(){
aNav[0].style.height = aNav[0].offsetHeight + 5 + "px";
if(aNav[0].offsetHeight >= 120){
clearInterval(animate);
}
},10);
}
aLi[i].onmouseout=function(){
var aNav = this.getElementsByTagName("ul")[0];
aNav.style.height = 0;
}
}
}
</script>求教育。这样并不管用哇
