PyPI now supports digital attestations, enhancing security and trust by allowing package maintainers to verify the authenticity of Python packages.
:cake: 不到1k, 一个mini的事件管理器, 希望能在您的代码中做一块砖.
npm i -S any-event
import EventEmitter from 'any-event';
const emitter = new EventEmitter();
emitter.on('add', data=>{
console.log(data) // 1
});
emitter.emit('add', 1);
绑定事件
名称 | 类型 | 数据类型 | 是否必填 | 说明 |
---|---|---|---|---|
eventName | 参数 | String/Symbol | 是 | 事件名称 |
listener | 参数 | Function | 是 | 对应的回调函数 |
emitter | 返回值 | EventEmitter | --- | 实例 |
解除绑定, 如果不填写listener
, 那么eventName
对应的listener
都会被移除.

const callback = data=>{
alert(data)
};
emitter.on('add', callback);
// 解除绑定
emitter.off('add', callback);
// add事件不会触发
emitter.emit('add', 1);
触发事件, 支持任意数量参数
名称 | 类型 | 数据类型 | 是否必填 | 说明 |
---|---|---|---|---|
eventName | 参数 | String/Symbol | 是 | 事件名称 |
args | 参数 | Any | 是 | 数据 |
emitter | 返回值 | Boolean | --- | 实例 |
const callback = (a,b,c,d)=>{
console(a,b,c,d); // 1,2,3,4
};
emitter.once('add', callback);
// add事件触发
emitter.emit('add', 1,2,3,4);
销毁实例
const callback = (a,b,c,d)=>{
console(a,b,c,d); // 1,2,3,4
};
emitter.once('add', callback);
emitter.destroy();
// add事件不会触发
emitter.emit('add', 1,2,3,4);
