angular.js - angular directive link event binding problem

Question

1. Why does setting up to prevent bubbling result in an error

Why do you get an error when setting the third parameter (false, true) when adding event binding? It’s okay if you don’t set it

2. Why is the binding tap event triggered twice?

If you change it to click it will be normal

Answer 1

1 .on( events [, selector ] [, data ], handler )
on ​​method api, the last parameter represents the event callback
The method to prevent bubbling is
2 .on("tap",function(e){ e.stopPropagation();})
3 If you are not using IScroll, it is recommended to use click. If you are using ISroll, configure click:true
