代码如下：
var br={};
br.eventRouter = {};
br.eventRouter.addListen = function(el,eventType,func){
if(!el.eventObjs){
el.eventObjs = {};
}
if(!el.eventObjs[eventType]){
el.eventObjs[eventType]=[];
br.eventRouter.bindListen(el,eventType);
}
el.eventObjs[eventType].push(func);
};
br.eventRouter.removeListen = function(el,eventType,func){
if(el.eventObjs && el.eventObjs[eventType]){
for(var i=0,len=el.eventObjs [eventType].length;ivar item = el.eventObjs[eventType][i];
if(func==item){
el.eventObjs[eventType].splice(i,1);
참을 반환합니다.
}
}
}
false를 반환합니다.
};
br.eventRouter.bindListen = function(el,eventType){
if(el.eventObjs && el.eventObjs[eventType]){
el[eventType] = function(e){
for (var i=0,len=el.eventObjs[eventType].length;ivar f = el.eventObjs[eventType][i];
f.call(el,e);
}
};
}
};
代码比较简单, 不做过多解释。
