jalali date input react component
npm install jb-date-input-react1400/12/08 or 1400_12_08
esm import build for modern ECMA Script nodejs app.
command
npm i jb-date-input-react
`
2- import package in your jsx file:
`js
import {JBDateInput} from 'jb-date-input-react';
`
3- use it in your jsx file like any other tag:
`jsx
`
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 character 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:
`jsx
`
valueType
we have 3 value type:
`jsx
`
min and max date limit
you can set minimum date and maximum date range for your app in string or Date type
`jsx
`
placeholder
you can set placeholder to show it to user when input is empty. to doing so just set placeholder attribute in JSX DOM:
`jsx
`
custom validation
beside of min and max you can also set your own custom validation like any other jb react components family to achive this you must create a array of validations and pass it to validationList props.
`js
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'
}
];
`
`jsx
`
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:
`jsx
// if in triggerInputValidation(showError) show error was false, in case of error,component wont show the error itself and the function will return if the data is valid or not
const MyForm = (props) => {
const dateElementRef = useRef(null);
const [validationResult, setValidationResult] = useState();
return(
)
};
`
events
- onSelect
`js
{console.log(event.target.value)}}>
`
- onChange
`js
{console.log(event.target.value)}}>
`
- onKeyup
`js
{console.log(event.target.value)}}>
`
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 JBDateInput you can specify how user must fill the date input.
to achive this you have to set inputType props or set inputType object to component directly using your elements ref.
to set it as props you can set value like this:
`jsx
`
and for doing it with direct DOM assignment you can use following js code:
`js
//to show gregorian calendar
const elementRef = React.createRef();
//set ref to element ...
elementRef.current.inputType = "GREGORIAN"
elementRef.current.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 calendarDefaultDateViewfunction like this:
`jsx
`
show persian number
if you want to show persian number instead of English number char you just have to set showPersianNumber prop like this:
`jsx
`
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 the react component with slot="calendar-trigger-icon" like below:
`jsx
`
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:
`jsx
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
`jsx
//if you want to check your overflow base on another dom and not window for example when you put date input in a modal
`
$3
in some cases in your project you need to change defualt style of react-component for example you need zero margin or different border-radius and etc.
if you want to set a custom style to this react-component all you need is to set css variable in parent scope of react-component.
#### usage example:
`css
body{
/ if you need more margin /
--jb-date-input-margin: 16px 32px
/ if you dont waant rounded corner /
--jb-date-input-border-radius:0px;
/ if you want different text color/
--jb-date-input-value-color:red;
}
`

`jsx
after
before
