Time range in EJ2 TypeScript Timepicker control
26 Apr 202310 minutes to read
TimePicker provides an option to select a time value within a specified range by using the min and max properties. The min value should always be lesser than the max value.
When the min and max properties are configured and the selected time value is out-of-range or invalid, then the model value will be set to out of range time value or null respectively with highlighted error class to indicates the time is out of range or invalid.
The value property depends on the min/max with respect to strictMode property.
The following example allows you to select a time value within a range of 9:00 AM to 11:30 AM.
import { TimePicker } from '@syncfusion/ej2-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
//creates a timepicker with min and max property
let timeObject: TimePicker = new TimePicker({
//sets the min value
min: new Date('3/8/2017 9:00 AM'),
//sets the max value
max: new Date('3/8/2017 11:30 AM'),
//sets the value
value: new Date('3/8/2017 11:00 AM')
});
timeObject.appendTo('#element');<!DOCTYPE html>

Time Range customization using two TimePicker components
Here, two TimePicker components are used to select the start and end time. The below sample illustrates the appointment time selection scenario with the start and end time option.
Before the start time selection, the end time TimePicker is in disable state. When the start time is selected, then you will be able to select the end time or else, need to select the entire business hours 9:00 to 18:00 from the Business Hours option. Once the options are checked, both the TimePicker components goes to readonly state.
import { TimePicker, ChangeEventArgs } from '@syncfusion/ej2-calendars';
import { CheckBox, ChangeEventArgs as checkboxChange } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';
//enable ripple style
enableRipple(true);
let value: Date;
let isStartTimeChange: Boolean = true;
let startTime: TimePicker = new TimePicker({
change: onEnableEndTime
});
startTime.appendTo('#start');
let endTime: TimePicker = new TimePicker({
enabled: false
});
endTime.appendTo('#end');
let checkboxObject: CheckBox = new CheckBox({ label: 'Business Hours', change: changeTime });
checkboxObject.appendTo('#dayRange');
let endInput: HTMLInputElement = <HTMLInputElement>document.getElementById('end');
function changeTime(args: checkboxChange): void {
/*To determine whether we have selected business hours or not*/
isStartTimeChange = false;
if (args.checked) {
/*Business hours*/
startTime.value = new Date('9/6/2017 9:00');
endTime.enabled = true;
endTime.value = new Date('9/6/2017 18:00');
startTime.readonly = true;
endTime.readonly = true;
} else {
endTime.value = null;
startTime.value = null;
endInput.value = '';
startTime.readonly = false;
endTime.readonly = false;
endTime.enabled = false;
}
}
function onEnableEndTime(args: ChangeEventArgs): void {
/*Enables end time if start time is selected*/
if (isStartTimeChange) {
endTime.enabled = true;
endTime.value = null;
endInput.value = '';
value = new Date(+args.value);
value.setMinutes(value.getMinutes() + endTime.step);
endTime.min = value;
} else {
isStartTimeChange = true;
}
