这种需求还是有的。比如多级页面里某个”消息红点“的传递，假设一个三级页面里某个item要显示小红点，然后它post出一个红点的事件，其中tag标识了自己所在的位置，然后二级页面根据tag中的位置将对应入口item也显示红点，然后一级页面也要根据tag中的位置将对应入口item显示出红点，可以想象，这种情况下实际一级页面入口item显示红点是响应收到多种tag的（因为二级里有若干个item，每个item点开的三级页里又有若干个item，而item发红点事件时为了标明自己的位置，不同item发的tag不能相同，所以此时一级页面对应item是应该要响应所有它内部页面发来的所有tag）
除非三级页面里给二级和一级各post一个他们对应tag的事件，但显然不优雅，当页面有五级、六级怎么办？难道还去post N个不同tag的红点事件？我希望是多级页面里只需post一个事件就能将红点一层一层的传递到外面去
