@zinliao/handybox v0.4.3

Who am I ?

I am an ECMAScript toolbox like handybox.

What type of function I have ?

Provides APIs not found in native JavaScript, involving Object, Array, Number, String, Time, and common tools, as well as support for use in Node.js

How to own me ?

1、Download from npm

npm install -s @zinliao/handybox

2、Use in your code

let handybox = require('@zinliao/handybox');

3、Happy to use all APIs

Do I have documentation ?

Online: Github - handybox

zObject

• pickNeedKey(obj, keys, isKeepKey)

let zObject = require('../zObject/index');

let obj1 = {
  a: 'a',
  b: 'b',
  c: 'c'
};

// { a: 'a', c: 'c' }
zObject.pickNeedKey(obj1, ['a', 'c']);

// { a: 'a' }
zObject.pickNeedKey(obj1, ['a', 'd']);

// { a: 'a', d: '' }
zObject.pickNeedKey(obj1, ['a', 'd'], true);

• serialization(obj)

let zObject = require('../zObject/index');

let obj1 = {
  a: 'a',
  b: 'b',
  c: 'c'
};

// a=a&b=b&c=c
console.log(zObject.serialization(obj1));

a.deduplication(true);

• pushAndShift(item, max)

let handybox = require('../index');

let a = [1];

// [1,2]
a.pushAndShift(2);
// [2,3]
a.pushAndShift(3, 2);

• max & min

let handybox = require('../index');

let a = [5,7,3,9,1,11,0];

// 0
a.min();

• removeSpecItem(index, item)

let handybox = require('../index');

let a = [1, 2, 3],
    b = [1, 2, 3];

// [1, 3]
a.removeSpecItem(1);
// [1, 2]
a.removeSpecItem(null, 3);

• in(item, isBackInde)

let handy = require('../index');

let a = [1, '2', 3];

// false
console.log(a.in(2));
// false
console.log(a.in(4));
// true
console.log(a.in('2'));
// 1
console.log(a.in('2', true));

    _int2 = 123456.789,
    _int3 = -12345,
    _int4 = -12345.789;

// 123,456
_int1.currency();
// 123.46k
_int1.currency(true);
// 123.5k
_int1.currency(true, 1);
// 123,456.789
_int2.currency();
// -123,456
_int3.currency();
// -123,456.789
_int4.currency();

• midian(target)

let handybox = require('../index');

let start = 10, end = -5;

// 2.5
start.midian(end)
// 3
start.midian(end, 0)
// 0
start.midian('-5')

zString

• upperFirst

let handybox = require('../index');

let str1 = 'hello world';

// Hello world
str1.upperFirst();

• strBoolToBool

let str2 = 'false';

// boolean
typeof str2.strBoolToBool();

• strNumRangeToArray

let handybox = require('../index');

let str3 = '1,2,3-5';

// [ '1', '2', '3', '4', '5' ]
console.log(str3.strNumRangeToArray())

zTime

• getMyTime(format, timestamp, area)

format

area

let zTime = require('../index')['zTime'];

let time1 = zTime.getMyTime('YYYY-MM-DD HH:mm:ss 星期day', null, 'CN');

// 2018-11-26 21:56:46 星期一
time1;

let time2 = zTime.getMyTime('YYYY-MM-DD HH:mm:ss 星期day', 1514736000000, 'CN');

// 2018-01-01 00:00:00 星期一
time2;

zTool

• debounce(func, delay = 300)

let handybox = require('../index.js'),
    zTime = handybox.zTime,
    zTool = handybox.zTool;

// debounce
let count = 0, delay = 1000,
    debounceLog = zTool.debounce(log, delay);

function log() {
  let now = zTime.getMyTime('HH:mm:ss');

  console.log(`count：${count}`);
  console.log(`Time：${now}`);
}

function main() {
  count < 5 ? setTimeout(_ => {
    count++;
    debounceLog();
    main()
  }, 0) : console.log('====== Over ======');
