AMP 中的事件

Events in JS

e.target = The thing under the mouse (as ben says… the thing that triggers the event).
e.currentTarget = The thing before the dot… (see below)

Event capturing is not supported in all browsers and rarely used. For instance, Internet Explorer prior to version 9.0 does not support event capturing.

Also, event capturing only works with event handlers registered with the addEventListener() method when the third argument is set to true. The traditional method of assigning event handlers, like using onclick, onmouseover, etc. won’t work here.

Events in Vue

Vue 还提供了事件修饰符，用以方便地处理一些非常常见的需求，从而把注意力集中到逻辑中去
