Introduction

• Support to obtain the current date and time, time difference, delay execution, customize multiple rotation training and other functions.

Features

• No matter how big the project is, only one timer is needed to reduce memory consumption and prevent application crash caused by too many timers.

Import

import timer from 'xbc-timer'

Methods

1、start(reset): start timing task

reset Boolean，Open single page task or not, that is, reset all timing tasks when entering a new page. The default is true, that is, open

timer.start()

2、remove(taskId): remove the task

// remove the task
timer.remove('test')
// remove multiple tasks
timer.remove(['test1', 'test2'])

3、clear(): remove all tasks

timer.clear()

4、delay(tasks): delayed task chain (each task is executed only once)

tasks: To delay the execution of tasks, it supports single (JSON) and multiple (jsonArray) at the same time. The parameters include：
func-Task name (special instructions, no parentheses)
delay-Latency in milliseconds
param-Task parameter, support legal format

// exec a single delayed task
timer.delay({
	func: this.test,
	delay: 5000
})
// exec multiple delayed task
timer.delay([
	{	// Delay execution by 5 seconds
		func: this.test1,
		delay: 5000
	},
	{	// Delay execution by 10 seconds
		func: this.test2,
		delay: 10000
	}
])

5、chain(tasks): timed task chain (each task circulates at specified intervals)

tasks: To circular the execution of tasks, it supports single (JSON) and multiple (jsonArray) at the same time. The parameters include：
id-TaskId
func-Task name (special instructions, no parentheses)
delay-Latency in milliseconds
param-Task parameter, support legal format
interval-Interval execution time, in milliseconds, default 1000
time-Timing execution time, support: yyyy-mm-dd hh:mm:ss、yyyy-mm-dd、hh:mm:ss

// Add multiple loop tasks at the same time
timer.chain([
	{
		id: 'test1',
		func: this.test1,
		delay: 2000,
		interval: 1000,
		param: 5
	},
	{
		id: 'test2',
		func: this.test2,
		interval: 1000,
		param: {name: 'test'}
	}
])
// Add multiple timed tasks at the same time
timer.chain([
	{	// Executed at a specified time (2 digits must be fixed for month, year, day, hour, minute and second)
		id: 'test1',
		func: this.test1,
		param: 5,
		time: '2021-05-22 12:00:00'
	},
	{	// Execute at the specified time of 00:00:00 on a specified date (when no time is passed in, 00:00:00 is the default)
		id: 'test2',
		func: this.test2,
		time: '2021-05-22'
	},
	{	// At a certain time point of every day (2 bits of time, minute and second must be fixed)
		id: 'test3',
		func: this.test3,
		time: '00:30:20'
	}
])

6、getYear(bool): get the current year

bool: Boolean, whether to get the complete year, true Yes (default), false no

timer.getYear()

7、getMonth(bool): get the current month

bool: Boolean, whether to get the complete month, true Yes (default), false no

timer.getMonth()

8、getDate(bool): get the current date

bool: Boolean，whether the fixed date is 2 digits, true Yes (default), false no

timer.getDate()

9、getYearMonth(bool, separ): get the current year-month

bool: Boolean，whether the fixed month is 2 digits, true Yes (default), false no
separ: The separation between year and year, default-

timer.getYearMonth()

10、getYearMonthDate(bool, separ): get the current year-month-date

bool: Boolean，whether the fixed month and date is 2 digits, true Yes (default), false no
separ: The separation between year and month, default-

timer.getYearMonthDate()

11、getDateTime(bool1, separ1, bool2, separ2): get the current datetime

bool1: Boolean，whether the fixed month and date is 2 digits, true Yes (default), false no
separ1: The separation between year month and date, default-
bool2: Boolean，whether the fixed houres minutes and seconds is 2 digits, true Yes (default), false no
separ3: The separation between houres minutes and seconds, default:

timer.getDateTime()

12、getTime(bool, separ): get the current time

bool: Boolean，whether the fixed houres minutes and seconds is 2 digits, true Yes (default), false no
separ: The separation between houres minutes and seconds, default:

timer.getTime()

13、getHours(bool): get the current hours

bool: Boolean，whether the fixed hours is 2 digits, true Yes (default), false no

timer.getHours()

14、getMinutes(bool): get the current minutes

bool: Boolean，whether the fixed minutes is 2 digits, true Yes (default), false no

timer.getMinutes()

15、getSeconds(bool): get the current seconds

bool: Boolean，whether the fixed seconds is 2 digits, true Yes (default), false no

timer.getSeconds()

16、getStamp(bool): get the current timestamp

bool: Boolean，set whether the unit is Ms. by default, the unit of time stamp returned when false is seconds

timer.getStamp()

17、getWeek(type): get the current week

type: Return the week format, optional values are：
0-周x，default
1-星期x

3-English
4-Short for English

timer.getWeek()

18、getDiff(timestamp): get the distance between a certain time and the current time

timestamp: timestamp，seconds or milliseconds

param.step: roll step number，default 1
param.start: start number，default 0
param.speed: roll speed，millisecond，default 10
param.formate: localeString，default false
param.change: listen roll number

timer.roll({
	number: 100,
	step: 1,
	change: number=>{
		console.log(number)
	}
});

20、countdown(param) count down

param.id: unique identifier
param.seconds: seconds
param.change: change callback, function
param.done: end callback, function return: return the currently instantiated countdown object

let oTimer = timer.countdown({
	id: 'test',
	seconds: 36,
	change: res=>{
		this.time = `${res.days}天${res.hours}时${res.minutes}分${res.seconds}秒`
	},
	done: ()=>{
		console.log('倒计时结束')
	}
});

contain methods：pause()、start(seconds)、restart(seconds)

1. pause() pause current countdown

oTimer.pause();

2. start(seconds) start current countdown
   seconds: optional, in seconds. If there is a value, the countdown will start from the current value

// the countdown will start from the pause value
oTimer.start();

// the countdown will start from the current value
oTimer.start(200);

3. restart(seconds) restart current countdown
   seconds: optional, in seconds. If there is a value, the countdown will restart from the current value

// the countdown will restart from the pause value
oTimer.restart();

// the countdown will restart from the current value
oTimer.restart(200);
