ProxyEvent

Install

npm i event-shadow

use

import { ProxyEvent } from 'event-shadow'
const proxyEvent = new ProxyEvent()
proxyEvent.addAfterGuard = function (ev) {
  // do something....
}

Info

new ProxyEvent(options)

options

• beforeGuard | 全局event前守卫 | 每次都会触发
• afterGuard | 全局event后守卫 | 每次都会触发
• node | 被代理元素 默认 HTMLElement.prototype

Event

• onBeforeGuard | 全局event前守卫
• onAfterGuard | 全局event后守卫

被代理的元素 new ProxyEvent({node: [document]})

Add Methods

• getEventListenerList(type) | type 事件类型
• firstGuard(type, callback) | type 时间类型 | callback 回调函数事件在所有事件之前执行 只会执行一次
• addBeforeGuard(callback) | callback 回调函数事件在所有事件之前执行 | 每次都会触发
• addAfterGuard(callback) | callback 回调函数事件在所有事件之前执行 | 每次都会触发

noShadow

new ProxyEvent({node: [document]})
document.addEventListener('click', function (e) { }, {noShadow: true})
document.removeEventListener('click', function (e) { }, {noShadow: true})

noShadow 开启影子模式 则firstGuard、 addBeforeGuard、 addAfterGuard、 onBeforeGuard、 onAfterGuard 将不会触发

taskQuene

import { taskQuene } from 'event-shadow'
const list = [function (evt, next) {

  console.log(evt)
  console.log(this)
  next()
}, function (evt, next) {
  console.log('this is 2')
  console.log(evt)
  console.log(this)
  next()
}]
const param = {value: '123'}
const obj = {name: 'obj'}
const a = taskQuene(list, param, obj)
a()

// this is 1
// {value: "123"}
// {name: "obj"}
// this is 2
// {value: "123"}
// {name: "obj"}
