instructions

getting started

using npm

1- install package:

npm i jb-date-input

2- import package in one of your .js file:

import 'jb-date-input';

3- use it in your .html file like any other tag:

<jb-date-input label="date label"></jb-date-input>

using cdn

beware that jb-date-input umd build do not exclude external dependancy and bundled as a standalone module, so only use this way if you dont access npm in your app.

1- you can just add script tag to your html file and then use web component how ever you need.

<script src="https://unpkg.com/jb-date-input/dist/JBDateInput.umd.js"></script>

2- use it in your .html file like any other tag:

<jb-date-input label="date label"></jb-date-input>

format

default format of date input is 'YYYY-MM-DDTHH:mm:ss.SSS[Z]' that compatible and exact format of new Date().toISOString() you can change it however you need and [Z] mean the exact Z charecter that used in ISO standard format YYYY-MM-DDTHH:mm:ss.SSSZ[Z] => 2012-06-21T00:00:00.000+3:30Z you can change format by format attribute:

<jb-date-input label="تاریخ" format="YYYY/MM/DD" value="2020/08/14"></jb-date-input>

Value Type

we have 3 value type:

    <jb-date-input value="2020-08-01T14:05:39.530Z" value-type="GREGORIAN"/>
    <jb-date-input value="1596291030322" value-type="TIME_STAMP"/>
    <jb-date-input value="1399-05-01T12:05:39.530Z" value-type="JALALI"/>

by setting value type you can tell component what type of value you provideing to it and expecting from it. remember that value type is not effect input type, for example user input jalali date but you will get gregorian date when call e.target.value. you can also provide and get js Date type for more performance if you like see "get value" section for get and for set just set value like: element.value = new Date().

min and max date limit

you can set minimum date and maximum date range for your date input in 2 way:

1- by html attribute in string format of your value

 <jb-date-input label="تاریخ شروع " value="2020-08-10T08:51:23.176Z" min="2020-08-05T08:51:23.176Z" max="2020-08-15T08:51:23.176Z">
 </jb-date-input>

2- by call setMinDate and setMaxDate function and providing string or Date format:

const today = new Date();
document.querySelector('jb-date-input').setMinDate(today)
const max = new Date('2022-08-15T08:51:23.176Z');
document.querySelector('jb-date-input').setMaxDate(max);
// or string
document.querySelector('jb-date-input').setMinDate('2022-08-15T08:51:23.176Z');

placeholder

you can set placeholder to show it to user when input is empty. to doing so just set placeholder attribute in HTML DOM or placeholder in JavaScript:

 <jb-date-input placeholder="Enter Date Here">
 </jb-date-input>

document.querySelector('jb-date-input').placeholder = `Enter Date Here`;

custom validation

beside of min and max you can also set your own custom validation like any other jb web components family to achive this you must create a array of validations and assign them to component

const validationList = [
        {
            validator:/^13.*$/g,
            message:'تاریخ باید تنها در قرن 13 شمسی باشد'
        },
        {
            validator:({text, inputObject, valueObject, valueText})=>{
                //you can use raw imputed text or formatted text in expected value in arguments
                //you have access to both jalali and gregorian date object here in valueObject
                //inputObject is a object contain imputed day & month & year unprocessed base on format so it have value before date imputed completely
                // remember valueObject and valueText are both empty and null when date is incomplete
                //if you want to validate incomplete date you can use inputText
                return valueObject.jalali.day == 15;
            },
            message:'باید تاریخ حتما  15 ماه انتخاب شود'
        }
];
document.querySelector('jb-date-input').validation.list = validationList

remember your min and max date must be in the same format and valueType of your value. to trigger validation and check is the element has a valid value:

// if show error was false, in case of error component dont show error itself and function will return if data valid or not
const showError = true
const validationObj = dom.validation.checkValidity(showError)

events

//when default property are defined best time for impl your config like min and max date
document.querySelector('jb-date-input').addEventListener('init',this.onCalendarElementInitiated);

//when calendar init all property and function and dom created and bind successfully
document.querySelector('jb-date-input').addEventListener('load',this.onCalendarElementLoaded);
document.querySelector('jb-date-input').addEventListener('change',(e)=>{
    //value in string
    console.log(e.target.value)
    //value in js Date object
    console.log(e.target.valueInDate)
});

date input type

jb-calendar support both jalali and gregorian(miladi) calendar input type. like value-type that let you determine how you want to provide/expect data to/from jb-date-input you can specify how user must fill the date input. to achive this you have to set input-type attribute or set inputType object to component dom directly. to set it as attribute you can set value like this:

<jb-date-input input-type="GREGORIAN"></jb-date-input>
<jb-date-input input-type="JALALI"></jb-date-input>

and for doing it with direct DOM assignment you can use following js code:

//to show gregorian calendar
document.querySelector('jb-date-input').inputType = "GREGORIAN" 
document.querySelector('jb-date-input').inputType = "JALALI"

set default date for calendar when opened

when date input value is empty we show today year and month in opened calendar by default but you can change it to another date. for example you want user fill they birthdate you can set it to 20 years ago so user can pick his/her birthday easier and faster. to doing so all you have to do is to use setCalendarDefaultDateViewfunction like this:

const year = 1360
const month = 5
//just set year and month for current input-type date type
document.querySelector('jb-date-input').setCalendarDefaultDateView(year,month);
//set default year and month for gregorian input-type
document.querySelector('jb-date-input').setCalendarDefaultDateView(year,month,'GREGORIAN');
//set default year and month for jalali input-type
document.querySelector('jb-date-input').setCalendarDefaultDateView(year,month,'JALALI');

get value

you can get the selected date by using following method:

    // return string value base on your provided format and value type
    document.querySelector('jb-date-input').value   

    // return javascript Date value (or null)
    document.querySelector('jb-date-input').valueInDate

note that providing & getting value with Date is faster and more perfomant than using value string

show persian number

if you want to show persian number instead of English number char you just have to set show-persian-number attribute like this:

<jb-date-input show-persian-number></jb-date-input >
//or
<jb-date-input show-persian-number="true"></jb-date-input >

customize calendar button trigger

you can change calendar icon base on your own need to doing so you just have to put your custom html inside web component with slot="calendar-trigger-icon" like below:

<jb-date-input >
        <div slot="calendar-trigger-icon">
            <svg xmlns="http://www.w3.org/2000/svg" version="1.1" x="0px" y="0px" viewBox="0 0 610.398 610.398">

Change Month List

you may want to change the default month list for both of Jalali and Gregorian calendars base on your country month labels. here how you can do it:

document.querySelector('jb-date-input').setMonthList('JALALI',['حَمَل','ثَور','جَوزا','سَرَطان','اَسَد','سُنبُله','میزان','عَقرَب','قَوس','جَدْی','دَلو','حوت']);
document.querySelector('jb-date-input').setMonthList('GREGORIAN',['1','2','3','4','5','6','7','8','9','10','11','12']);

overflow handler

sometimes you place date input inside modal or end of the pages so when user open the input picker it overflow the page and some part of picker will be invisible.
to fix this we add a feature called overflowHandler by set this to SLIDE the picker will move, on mouse enter it's territory so user can easily pick date

document.querySelector('jb-date-input').elements.popover.overflowHandler = "SLIDE"

set custom style

in some cases in your project you need to change default style of web-component for example you need zero margin or different border-radius and etc.
if you want to set a custom style to this web-component all you need is to set css variable in parent scope of web-component.

usage example:

body{
/* if you need more margin */
  --jb-date-input-margin: 16px 32px;
/* if you dont want rounded corner */
  --jb-input-border-radius:0px;
/* if you want different text color*/
  --jb-input-value-color:red;
}

you can customize jb-date-input look by setting css variable in your app.
jb-date-input use jb-input and jb-calendar and jb-popover underneath so to change the styles of your component read custom style section of these components and set their css variable.
more than above here is the css variable that we use in jb-date-input itself:

variable list

css variable name	description
--jb-date-input-margin	web-component margin default is `0 0`
--jb-date-input-calendar-trigger-display	set it no none to hide calendar icon
--jb-date-input-calendar-trigger-width	set calendar icon width
--jb-date-input-calendar-trigger-height	set calendar icon height

add custom element in input box

in jb-input you can put icon or any other custom html DOM in input box. to doing so you just have to place custom DOM in jb-date-input tag and add slot="start-section" or slot="end-section" to place it before or after input field. example:

<jb-date-input>
    <div slot="end-section">after</div>
    <div slot="start-section">before</div>
</jb-date-input>
