在FireFox浏览器上，用stopImmediatePropagation阻止冒泡鼠标滚动事件

楔子

是不是在火狐用stopPropagation不太满意很久没有笑过又不知为何既然不快乐又不喜欢这里不如一路向西用stopImmediatePropagation（其实我对浏览器的兼容性看不顺眼已经很久了，殊不知浏览器对我的想法更不顺眼，甚至嗤之以鼻）

注释

言归正传，让我解释一下stopImmediatePropagation的用法：如果多个监听器连接到同一事件类型的同一元素，则按添加监听器的顺序调用它们。如果在一个这样的调用中调用了event. stopimmediatePropagation()，将不会调用剩余的监听器。

实例

我将用DOMMouseScroll事件类型，滚动鼠标轮就触发事件，此事件类型非常兼容FireFox浏览器，其它主流浏览器不支持，再重复一遍，在FireFox运行有效果，其它主流浏览器则没有。

不添加stopImmediatePropagation时，体会冒泡一下。

        console.log("我是外面");
     });
     document.getElementById("lw").addEventListener("DOMMouseScroll",function(e){
        //不添加stopImmediatePropagation，如果我滚动鼠标，事件触发，控制台输出“我是里面”的字符，由于此节点的父节点也有相同事件类型的事件，并且符合触发条件，因此，打印输出“我是里面”后，也会打印输出“我是外面”，姑且称它为冒泡。为啥这样？此博不侧重讲这个问题，只注重讲解标题。
        console.log("我是里面");
     })
  </script>
 </body>

添加stopImmediatePropagation后，体会冒泡怎么就阻止了？
