yzhang921 opened a new issue #10551: 绑定事件能够给定一个明确id
URL: https://github.com/apache/incubator-echarts/issues/10551
 
 
   ### What problem does this feature solve?
   目前echartsInstance.off, 事件解绑方法，两种格式一种是全部类型的事件都解绑，另外一种传递function，文档上说有function传递的情况下能够只解绑传递的function，但是测试了一下没有效果；不知道内部是通过什么机制追踪eventHanlder的，觉得如果能够让用户绑定事件的时候给定一个明确的id，这样在绑定多个不同的事件，如click、click alt，click ctrl多个不同的事件，能够精确解绑。
   
   ### What does the proposed API look like?
   echartsInstance.on('click', id, function() {})
   echartsInstance.off('click', id)
