event-shadow v1.0.27
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('this is 1') 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"}
> taskQuene
