    function stopBubble(e){
        if(e.stopPropgation){
            e.stopPropgation();
        }else{
            e.cancelBubble=true;
        }
    }

阻止系统自带功能

   function preDef(e){
        if(e.preventDefault){
            e.preventDefault();
        }else{
            e.returnValue==false;
        }
    }
