基础 ​

now ​

ts
import { base } from "@binary-star/aencap";
const { now } = base;
const t = now();

includeKeys ​

ts
import { base } from "@binary-star/aencap";

const { includeKeys } = base;

const t = includeKeys({ name: "zhangsan", age: 15, gender: 1 }, [
  "name",
  "age",
]);

console.log(t); // { name: 'zhangsan', age: 15  }

each ​

ts
import { base } from "@binary-star/aencap";

const { each } = base;

each({ name: "zhangsan", age: 15, gender: 1 }, ({ key, value }: any) => {
  console.log(key, value);
});

// name zhangsan
// age 15
// gender 1

map ​

ts
import { base } from "@binary-star/aencap";

const { map } = base;

const t = map(
  { name: "zhangsan", age: 15, gender: 1 },
  ({ key, value }: any) => {
    if (key === "age") {
      return 20;
    }
    return value;
  }
);

console.log(t); // { name: 'zhangsan', age: 20, gender: 1 }

convertToChinaNum ​

将 数字转换为中文大写单位 如：1234567890 -> 十二亿三千四百五十六万七千八百九十

ts
import { base } from "@binary-star/aencap";
const { convertToChinaNum } = base;
convertToChinaNum(1234567890);

sleep ​

返回一个 Promise，等待指定的时间后 resolve

通常可以搭配 async / await 使用

ts
import { base } from "@binary-star/aencap";
const { sleep } = base;

const start = async () => {
  await sleep(3000);
  console.log("start");
};

start();

secondToString ​

时间戳转换为时间字符串

ts
import { base } from "@binary-star/aencap";
const { secondToString } = base;

console.log(secondToString(120)); // 120 -> 2 分钟

linkSet ​

使用 '.' 进行深度设置对象值

ts
import { base } from "@binary-star/aencap";

const { linkSet } = base;
const data = {
  user: {
    name: "John",
  },
};

linkSet(data, "user.name", "Alice");
console.log(data.user.name); // Alice

linkGet ​

使用 '.' 进行深度获取对象值

ts
import { base } from "@binary-star/aencap";

const { linkGet } = base;
const data = {
  user: {
    name: "John",
  },
};

console.log(linkGet(data, "user.name")); // John

toFixed ​

ts
import { toFixed } from "@binary-star/aencap/base";

console.log(toFixed(12.3444444, 2)); // 12.34

computeTwoNumber ​

两个数进行运算

ts
import { computeTwoNumber } from "@binary-star/aencap/base";

console.log(computeTwoNumber(1, 2, "+")); // 3

splitIgnoreQuotes ​

将字符串以 “,” 进行分割， 但不包括字符串中的 “,”

ts
import { splitIgnoreQuotes } from "@binary-star/aencap/base";

console.log(splitIgnoreQuotes('a,b,c,"d,e,f"')); // ['a','b','c','"d,e,f"']

callDispatch ​

返回将目标对象的指定方法给增加一层包装, 在某些不能及时获取到目标对象时做的一层转发函数

ts
import { callDispatch } from "@binary-star/aencap/base";

const target = {
  click() {},
};
// target 也可以为一个函数, 为: () => target
const t = callDispatch(target, "click");
t();

应用场景常见于 vue 的 defineExpose 中需要暴露其中 ref 的方法, 我们可以使用该方法来进行派发

parseTemplate ​

用于替换模板字符串功能 , 比如: "${username} 你好" 替换为具体的变量 : zhangsan 你好 , 或者用于表达式功能 , 比如 : "${flag} === true" 为: true === true

ts
import { parseTemplate } from "@binary-star/aencap/base";

const t = parseTemplate("Hello ${username}", { username: "zhangsan" });

console.log(t); // 'Hello zhangsan'

// 也可用于表达式
const t1 = parseTemplate(
  "${username} === 'zhangsan'",
  {
    username: "zhangsan",
  },
  true
);

console.log(t1); // 'zhangsan' === 'zhangsan'
