Enums利用类组件实现枚举

class Enums {
  constructor(enumsName) {
    this.enumsName = enumsName;
    this.data = {};
    this.alias = []; //别名
  }

  //
  set(name, value) {
    this.data[name] = value + "";
    return this;
  }

  // 根据name得到value
  get(name) {
    return this.data[name];
  }

  //根据value得到name
  searchName(value) {
    return Object.keys(this.data).find((name) => this.get(name) === value + "");
  }

  getData() {
    return this.data;
  }

  setData(data) {
    this.data = data;
    return this;
  }

  getFirstValue() {
    const data = this.getData();
    return data[Object.keys(data)[0]];
  }

  setAlias(name) {
    //设置别名
    this.alias.push(name);
    return this;
  }

  is(nameOrAlias) {
    return this.enumsName === nameOrAlias || this.alias.includes(nameOrAlias);
  }

  clone() {
    const cloneEnums = new Enums(this.enumsName);
    const data = this.getData();
    Object.keys(data).forEach((key) => {
      cloneEnums.set(key, data[key]);
    });
    this.alias.forEach((aliasItem) => cloneEnums.setAlias(aliasItem));
    return cloneEnums;
  }
}

enums.js

import Enums from "util/Enums";

const enums = [
  new Enums("是否").set("是", "1").set("否", "0"),
  new Enums("性别").set("男", "1").set("女", "0"),
  new Enums("启用禁用")
    .setAlias("禁用启用")
    .set("启用", "1")
    .set("禁用", "0"),
];
export default (enumsName) => {
  return enums.find((item) => item.is(enumsName));
};

export const getEnumsOption = (enumsName) => {
  const data = enums.find((item) => item.is(enumsName)).data;
  const option = [];
  Object.keys(data).forEach((key) => {
    option.push({ label: key, value: data[key] });
  });
  return option;
};

使用enums

import getEnums from "enums";
const settingTypeEnum = getEnums("启用禁用");
