关于取消冒泡的问题~请教大家了
JScript code<script type="text/javascript"> var oDiv=document.getElementById('div1'); function addEvent(obj, ev, fn){ if(obj.attachEvent){ obj.attachEvent('on'+ev, fn); }else{ obj.addEventListener(ev, fn, false); } } function cancelBub(ev){ var ev=ev||window.event; if(ev.cancelBubble){ ev.cancelBubble=true; }else{ ev.stopPropagation(); } } function aa(){ alert('aa'); } function bb(){ alert('bb'); } function cc(){ alert('cc'); }; addEvent(document, 'click',aa) addEvent(document, 'click',bb) addEvent(oDiv, 'click',cc)</script>
cancelBub是取消冒泡的函数，那我如何只取消addEvent(oDiv, 'click',cc)这个的冒泡呢？请教了~~

------解决方案--------------------
<script type="text/javascript">
var oDiv=document.getElementById('div1');
function addEvent(obj, ev, fn){
if(obj.attachEvent){
obj.attachEvent('on'+ev, fn);
}else{
obj.addEventListener(ev, fn, false);
}
}
function cancelBub(ev){
var ev=ev||window.event;
if(!ev.cancelBubble){
ev.cancelBubble=true;
}else{
ev.stopPropagation();
}
}

function aa(){
alert('aa');
}

function bb(){
alert('bb');
}

function cc(){
cancelBub();
alert('cc');
}

addEvent(document, 'click',aa);
addEvent(document, 'click',bb);
addEvent(oDiv, 'click',cc);
</script>
------解决方案--------------------
我改了两处，一处cancelBub函数
if(!ev.cancelBubble)
另一处function cc()里加上cancelBub();------解决方案--------------------
如果ev.cancelBubble为假才需要把它设为true啊
------解决方案--------------------
因为cancelBubble默认是false
