touchcancel事件不触发scrollEnd事件

[chenyulun]

Version

2.1.1

Reproduction link

https://github.com/chenyulun/better-scroll/blob/dev/packages/shared-utils/src/dom.ts

Steps to reproduce

Android 设备滚动的时候，有机会不触发hooks.on('end',hander)事件

What is expected?

希望touchcancel触发end流程

What is actually happening?

Android 设备滚动的时候，，有机会触发touchstart->touchmove->touchcancel;
这种情况下绑定‘end’事件不触发；

---

其实项目中监听了touchcancel的事件执行end钩子函数，但是eventTypeMap里面没有配置touchcancel事件为触摸事件;

export const eventTypeMap: {
  [key: string]: number
  touchstart: number
  touchmove: number
  touchend: number
  mousedown: number
  mousemove: number
  mouseup: number
} = {
  touchstart: 1,
  touchmove: 1,
  touchend: 1,

  mousedown: 2,
  mousemove: 2,
  mouseup: 2,
}

添加touchcancel: 1事件即可
