xms-basic-util/src/ringCenter/sequence.js

js基础工具类集合,集成方便后期调用，通过webpack编译，支持多种平台，如es6、node、浏览器引入等 ## 使用 ### es6方法 - 安装 ``` npm install xms-basic-util ``` - 导入 ``` import xmsBasicUtil from 'xms-basic-util' //日期转换工具对象 const dateFormat = xmsBasicUtil.dateFormat; //数字处理工具对象 const mathUtil = xmsBasicUt

// 默认值
const SequenceConfig = {
  idx: 0
}

// 主键生成器
class Sequence {
  constructor (incr = 1) {
    this.incr = incr
    this.config = SequenceConfig
  }

  increaseIdx () {
    this.config['idx'] += this.incr
    return this.config['idx']
  }

  next () {
    const idx = this.increaseIdx()
    return idx
  }
}

// 测试
const sequence1 = new Sequence()
const sequence3 = new Sequence()
const sequence2 = new Sequence()
console.log(sequence1.next())
console.log(sequence2.next())
console.log(sequence3.next())
console.log(sequence1.next())
console.log(sequence2.next())
console.log(sequence3.next())
console.log(sequence1.next())
